Welcome to the Leftfield Games, we're

basically going to start now. So pretty

much I'll explain the rules how it went.

So everyone was given 31 days to

complete their project, right? By March

31st, March 31st now. The requirement

was you had to create a full-scale

application from front end all the way

to back end to qualify and you had to

host and deploy your app. The top three

people that we believe have the most

completed project and it doesn't matter

if you like what level you are, right?

We're going to critique it to your

level. Mhm. experience. So that the top

three people will get like a mini

one-day mentorship from the Leftfield

team and will get a customized road map

to be able to hopefully use that to

break through into tech. Uh Phil, do you

have any words to say, any words of

wisdom, advice to everyone who

participated?

Yeah, I mean like like I said earlier,

like you know, it's like the it's hard

work, like it's like a piece of art. I

always think of it like a piece of art

that you're putting out, so it's like

your passion. And

you put it out there for everybody to

use and you know, if it's not complete,

but if it's working, that's totally fine

cuz it's like you can always update it

and keep working on it. But I want to

thank you and like on behalf of like

Leftfield or whatever, like uh thank you

for participating and let's get the game

started. All right, guys. The first one

is actually uploaded this morning from I

think your friend Phil Matos. He did

something really cool. I don't I do want

to give a lot of love to it. I'm not

exactly sure how he made this, but maybe

you'll have a better idea. I'll just

link this in the chat room here in the

community post. You guys can all click

on it, look at it. Take a look. There's

like any login or anything like that,

but I found I found that this is really

cool. Yeah, um this is a this is the

Seoul like subway train station um app.

So there's a lot of cool stuff here.

He's using um

some kind of map API with some polygons

drawn to show like um Seoul and then

Gyeonggi-do and then like all the

provinces and stuff like that and where

the train station goes. Uh Matos was

talking to me a little about about a

little bit and um

I guess from where you are at City Hall

the blue takes 15 minutes to get to.

Um the orange takes 30 minutes to get to

and the 60 this takes like an hour to

get to. It's pretty cool. It's hooked

into the Seoul API. I think he scraped

it and I think whenever Matos comes to

South Korea he always gets a lot of

he wants to come back all the time.

And

taking the subway and the train at in

Korea is like it's an experience in

itself. Everything is so connected and

it's always really fun. But this is

really cool. If you actually like take a

look

let's take a look at the inspector here.

So

let's refresh. See how it's working.

He has some kind of

API that he's running called

uh and then he's passing in some kind of

thing here.

Uh let's see what the response is.

Okay, that's pretty cool. Um

these are all the tiles I guess from the

map.

There's keys all here, but okay.

And

so he's using this map tiler

um to get the map shown. I guess it's

the Korean API cuz it has all the Korean

stuff. Who knows?

Looks pretty good and then the GeoJSON

for the polygons.

Awesome. It's coming into.

Which is which are just coordinates to

draw the polygons. They're pretty cool.

Um

I think when he's

you know, working with these map stuff

and all this kind of stuff is uh

pretty interesting. It's cool that he's

not doing live requests and he actually

put in his own like database. Mhm. Um

So like if you actually look here, this

is probably his GeoJSON

file that he has statically put that he

already collected

in his website and if you you know, you

can put pop this in any map API and it

could draw the polygons for

whatever it is. It's probably pretty

heavy cuz

what's going to probably going to happen

is if I put myself at a different place

right?

Let's put

my uh

I don't know. Um

I don't know if you guys ever heard of

Hongdae.

It's going to show you a different

polygon for every single station, right?

From what you can get to from in 15

minutes 30 minutes and 60 minutes and

that's going to have a different uh

GeoJSON file for every single one. And

it's a huge file, I think.

Mhm, yep. But this looks cool. It looks

like people would use it. And it's

pretty useful cuz then uh we I think

I'll send this to Damian cuz then you

can figure out you know, how long

something could takes to get to.

Pretty cool. Um let's move on to the

next app, shall we? Yeah. So welcome to

next panel. So it's for Korean manhuas,

so like Korean animes, right? Your

personal space to track uh manga, manhua

and manhua. Build your library, keep up

with your uh so I guess you just um

I guess they really like solo leveling

and they've um you know, there's so many

of these animes and manhuas like

you have to keep track of which number

you're on, what which ones you've read

and all this kind of stuff. It's pretty

cool.

Um let me see. Let me browse series.

It's pretty cool. So he's hooking up

into some API

to get all these

animes somewhere.

So next panel API

and then he has a response and you have

all these APIs that he scraped

to get these

What is this called? Animes? Yep. Yeah.

It's pretty cool. I like that he made

his own API and

I really

think that's cool. I guess the main main

thing is called onrender.com.

But he has a back end that's running on

onrender.com. That's pretty cool.

Librarie, do you have any comments about

this one?

Let's see the cache. I'll I'll let you

take it

a look at it and it was

it's pretty good and I also noticed it

was very fast as well, which was

not something you would see any just

anywhere. Yeah. It

calls real quick. It's real good. It's

it's very check the responsiveness of

it.

Mhm.

Mhm.

>> [clears throat]

>> It's pretty good.

>> Yeah. Um It's very responsive.

Just uh

I think it's pretty good, but I I would

I don't know if there's any caching

system here.

But um

seems to be making this request pretty

fast and let's see his

See this uh

>> Oh man. dragon Okay. All right, there

you go. There you go. It needs the

space. So

maybe I don't know how he's doing the

searching, but um

that's maybe some other stuff can be

implemented here to kind of help that.

Some kind of rejects or something like

that. Uh and have some matching score.

But that's pretty it's pretty good. I

like it a lot. And um

I like I like anime a lot like One Piece

and Dragon Ball and um

Do you? What is an uh

>> [laughter]

>> And I mean if you actually wanted to

make this better and like my suggestion

is like looking at Elasticsearch. That's

going to like

help this searching part a lot more.

my opinion

and I guess there is some kind of use

debounce kind of thing here

cuz I see it right now.

And um

I like that.

So it's probably making a request on use

debounce. So you see this.

But

how it should work is you should

probably use like

you know, an index search index kind of

thing like Elasticsearch or I know that

there's like a open source one called

MeiliSearch. I always really wanted to

use it.

But I really

I think it's really well built and this

one seems really good. So you just like

add all your databases that you all your

items or documents that you want to

actually search for inside of a search

index kind of database and um

and then it and then there's like some

kind of things where like it uses

rejects or something and it gets you the

hits of like what's similar and then you

show those

on your

on your subject. Thank you guys for

you know,

helping out and also um

you know, if you guys still have apps

that you haven't uploaded yet, please

you know, drop it in there. We're going

to do this you know, quite frequently.

So don't be afraid to share.

It's always good. For sure, for sure. I

just want to see one more thing.

Um

>> Oh, the guy is here. Oh, he's here?

Yeah, RXD. Oh, hey RX uh

G

GVN

RXD uh amazing. Mhm. Uh

uh we there's a new anime guy that I'd

like to connect you to. What's his um

Who's the new mentee from last week?

Remember? Mini

or

I forget.

>> That

West? Yeah, yeah, I think so.

Let me let me just check. Let me let me

connect you with him. I think he's

really into anime, too.

But um Just looked at your app and we

just talked about like how you can

improve it and like how you did great.

What what things you did also. Um just

watch the video for it. It's pretty

cool. I like it. I like it a lot.

Awesome. Awesome. Thank you.

GNV GVN, how how long have you been

coding for?

And after that a year ago, that's that's

amazing, man. For just a year. Mhm.

Really good.

Good app.

Good work. Keep up the good work, man.

All right, the next This is pretty

interesting.

By this guy 59463.

So and automated invoice reminders for

freelancers and small businesses.

Hello 5946

3

Remite, so like remittance for like

movie move money something. Now in early

access stop chasing later invoices.

Keep cash moving. Pretty cool automated

reminder emails for freelancers and

consultants.

That's cool.

So I like the landing page a lot, right?

I like that it's like a full product.

Cuz like whenever you think about a

product, you know, everybody thinks

about building the app or whatever, but

you need to build a landing page.

You need to build the app. You need to

build the admin panel, the server. And

those four things are going to equal um

a business online.

Mhm. Those four.

Not just the app. But uh how Remints

works, you create an invoice, set the

schedule.

So for subscription or payment plan.

And it sends follow up emails when an

invoice is marked un uh

and stops when the invoice is marked

paid.

Okay, that is cool. I like it a lot.

He probably saw a problem in his um in

their space.

And try to figure it out. Let me let me

try the demo real quick. Can I Can I

drop an invoice in here or something or

invoices So what if I want to

I like that they did a demo too. That's

awesome.

>> man.

Schedule

and 3 days before due date.

Set two due dates, set three five days

after. So these are the sequence I have

I guess.

And then 25 days after due date. It'd be

kind of cool if

you know, if it's you added some late

fees as well or something like that if

you could include that in your contract.

Who knows? But that's cool like reminder

frequency. So I could do like a 14-day

reminder. Oh, and it uses AI to like

make the messages a little bit That's

cool, too. That's cool.

Turn that off.

That's cool, man.

I like it a lot. I think I think it

solves a real problem, right? But when I

actually

I can mark it as paid, but do I have to

How do I upload the invoice?

That's the one thing I'm I'm looking

for.

Invoices. No emails are sent, that's

fine, but how do I create the invoice?

Let's check the search.

So this this is It says that we we

import them from exterior. Ex- Excuse

me? It says to import them for invoices

from exterior.

Okay, okay.

Or add them manually in minutes. So you

basically have to create it yourself and

then this is the the software to remind

them.

Okay, okay.

That's [snorts] a

Acme Corpis.

Kind of an huh?

But uh

Okay, that's cool. And um

Wait,

maybe in the search this invoice search

that's kind of the same thing that we

have with the next panel, right? And

there's no use the balance here either.

But I guess it is just filtering through

the already stuff. Like it's not making

a request, so that's totally fine.

All right, that's uh I like this. I

think it solves a real problem.

Cool. Yeah.

All right,

the next one we're going to do

[clears throat] I think it's actually

deployed on Google. Wait.

Okay, instantly instantly know the true

value of everything. Point your camera

at any object or AI identifies instantly

and scans thousands of marketplaces to

give you the real price.

That's freaking awesome. That's

Yeah. So

um

especially for like it's I think if you

make it really well, like um

it's really good to incorporate into

like a used marketplace cuz I think in

Singapore they created this in like 2000

They tried to create this in 2019 at a

startup.

And they did really well and it got

incorporated into um

into Tangent Market or Carrot Market.

It's like a Korean news market app.

And when you actually

post like some used market item um you

can ask for a price suggestion. And

one other thing is you can create like

the

the actual post

with AI.

So it helps you make the post and like

the price as well.

But I mean that's that's pretty cool.

um

Is there any way we You don't have an

Android, right, Phil? I do not have an

Android. Wait, wait, I do have one on my

tablet, but I think it's out of

batteries.

Uh hey, um

But like wait, do you have an Android by

any chance?

No, I used to have an Android. Okay.

Is it only Is it only on the

um Android Marketplace? It's not like

APK file

that you can download as well. No, no,

it's uh

Well,

I think on the iOS it's on the wait

list, but they just made it on Android.

That's cool though. I I I like that it's

taking into account like location.

Mhm. [clears throat]

um

And it's taking into account like um

I guess like

all their scan history stuff. So the

more people use it, the more it's going

to get better. So instead of just

relying on open AI

and real-time conversion, that's cool.

um

I think

one other thing that you could add is

like the you could make AI descriptions

as well, which is would be pretty cool,

too.

Just make that like just take a photo

and upload it and then maybe you could

hook it up to like the second hand

market, too, like where you could put

like

I don't know. Facebook Marketplace,

zero radius or something like this. I

don't remember at all. But you like you

hook up and then like in one picture you

could upload it to like several

marketplaces and manage it from there.

Who knows? But that's cool. I like it.

Yeah.

Okay, price it. If anybody has a

Android, please check it out. I guess of

you.

Our gentleman here. And

I guess like like a tea dude,

I think it'd be nice if you also make

like a little demo video for people who

don't have Android, that'd be sick.

Yeah. Oh, yeah. Thank you. I like it. I

like this kind of stuff a lot.

I I like selling stuff on the used

marketplace, buying stuff from there,

too.

So

solves a real issue.

Yeah, this is really handy for resellers

as well like who want to go to garage

sales and they want to find prices for

stuff. That's so true. That is so true.

Yeah, and they're like oh, how much does

this cost and boom they find the price

real quick.

Gary

Gary like

adding like a demonstration kind of like

how to utilize it would be pretty cool

as well because when you see like a demo

like that's what gets people to buy.

>> [clears throat]

>> When you When you see someone basically

utilize it and just put it on either

mobile and desktop

I think that'd be really solid. All

right. All right. Yeah. I think Chris is

here as well, actually. It looks like a

you know, like Duolingo for code. I

thought it's done really well. Like it

looks like the same style.

um

Get started for free and then you get

like the SQL. I think they're in Kes

Dez. I don't know what language this is

in actually.

But um

Oh, Chris is here.

So the description here Okay, so you can

just go to your SQL. He said the back

end uses Spring Boot with Postgres SQL

database. That's awesome.

>> Loads the lesson content from a YAML

file at startup.

That's awesome.

So like uh which command do you use?

>> and TypeScript. That's cool.

>> That would be I like I like this a lot.

This is our This is really interesting.

It looks just like Duolingo.

What does create database if not exist

command

>> what's up, man? Chris is on the board.

Yeah, I'm not quite sure what this

means. I think it's German.

Like I don't know how much like this was

built just by hand cuz it should take a

long time.

But it reminds me of Duolingo a lot.

But um

I really like this.

Really interesting. It's fun.

Okay.

>> thread It's the Reddit clone. Oh, I

really like this one and I really like

how like in-depth it was. It was like

the Reddit clone and if they I like it I

liked it cuz

he added like the you know, the nuances

of like Reddit like

the comment like threads and stuff like

that, the up votes.

But done really well and um

Yeah, like this is a very complete

project, I think.

Like

it's really good.

And not enough people are using it. I

feel like if we change this to

put a little bit more I don't know.

If our community you wanted to use this,

it would be a really um

it'd be really interesting for us to use

and kind of

put on the map. I don't know if we have

the power to do that. I think we do have

the power to do that.

But that'll be really fun.

But yeah. I I think this is really well

built.

Uh has recently visited. You can see the

comments and you can see like the

threads.

Close threads.

I think that's really cool.

Um and then we'll just do one more. Is

that cool, Phil? Yeah. Okay, give me a

sec.

Lost that page real quick. Share.

I wanted to find the cloud one, the the

virtual world. Can't find it. I

think I have it in my uh thing.

Cloud cloud town.

Cloud town, yes. Let's see.

Um

This one's pretty cool. It looks like a

gather town a little bit.

Yep. Um I can you go in here, too, and

see if I can see you?

Yeah, let me just check it out real

quick. It's cloud town. I'll

I'll make it so

>> It's saying one player online right now.

Okay, cool. Come in.

I know with Discord. Let's see if that

works.

That's what I sign in with.

It's pretty cool. I can see that there's

two people online. I can see that I'm

moving very sparkly and I I'm by the

cloud house.

Oh, I see you guys. There. Yep. Now,

let's see if there's some interaction

that goes on.

Yeah. Wait, is there any interaction?

I guess not yet. Okay. Cuz like gather

town and stuff like that, you know, when

you come close to each other it opens up

like uh chance to chat with each other

and stuff like that. Like a like a

dialogue? Yeah, yeah. Yeah. Yeah,

there's no

It's pretty cool. I like it. I wonder

how they made it.

Right.

This is like a mini town.

Yeah, but this kind of stuff is like

really cool like if um

you know, if you're studying and you're

just like here it's like showing that

you're not alone studying or something,

you know?

Mhm. So you can just like

I don't know if you guys ever used

gather town, but it's like the same kind

of concept.

We should make Less Social into this

stuff.

That'd be sick. Kind of cool.

Yeah.

Yeah, this is pretty cool.

I like it a lot.

Awesome. Well, I think we'll pause it

here

and we'll just continue this maybe next

week. Yeah, let's do that.

Yeah, let's do we'll do another event,

the same one this week.

I mean next week and then we'll finalize

the winners and things like that

afterwards, but uh yeah.

>> talk about it later on. I you know, I

really like syntax owl. I like um price

it, but I would like to like um

kind of like actually use it.

Mhm. Verbatim was really cool.

Um

isochronal is really cool. But uh yeah,

I mean very good job everybody and um

uh we'll we'll take a more in-depth look

at all of the uh projects and uh we'll

come up with our some rankings. Um

They're all number one. To be honest,

they're all really good. But um you

know, we uh there we will choose a

winner and uh we'll reach out and um

we'll uh announce it as well. Yeah,

brilliant. Um please submit your

projects at Show and Tell. Thank you

very much and uh have a good one. All

right, everybody. Just remember, if I

can do it, you can do it, too. Coding

saves lives.
