Skills

Resume


Hello there! My name is Matěj and I’m from Tábor, Czech republic, where I’m studying 3rd grade of high school. I’m currently looking for an internship or a part-time job I could do while studying. Here you can find a showcase of what I can do and what I’ve done.

You can see my preferred technologies in the column below my photo. Until quite recently I considered Python my strongest point, but in March I learned Svelte and frontend became a pleasure again. I still don’t know the big frameworks like React or Vue, though I’d still like to learn them one day. However, I’m a a terrible frontend designer, and not even Bootstrap or Bulma helped me.

Projects

Python mailmerge

A simple but fully functional mailmerge script written in Python using Jinja and Markdown.

Bakatasklist

A simple web app for better management of homework. This rushed project is not usable anymore due to external API deprecation. I created this during first COVID-19 lockdown in March 2020, because at that time, our school IT system turned out to be completely unusable for student once there are more than a few assignments.

Homework – Fully Merged List

A second iteration of the above. I started making this in October 2020, when the second lockdown wave struck, but then I got stuck on designing the frontend, and Bakaláři (the mostly harmless Czech school IT system) implemented the main feature my app was bringing to the table, so the work on this stopped. But I’m still proud of the API abstractions I pulled off and would like to finish this one day…

EYP Calls scraper

A scraper + simple presentation of participant calls from the European Youth Parliament members platform. Utilizing Python Scrapy + Cloudflare Workers

Starlette Websockets demo

A a demo of using the Python Starlette framework for websockets-based server to client notifications. The server can dynamically create and delete channels, which are advertised to the connected clients. The clients can then individually subscribe to each channel and receive the notifications. I created this to learn Starlette and Websockets, as I’m planning to use a similar architecture for a project I’m planning to do.

Finding ways how to host stuff for free

Seriously. Bodge together some Heroku, Cloudflare reverse-proxy + workers free tiers, Freenom .tk free domains and ImprovMX+Gmail+DKIM and you have a full webhosting including automated emails for free.

The email thing is probably my favourite part: ImprovMX can “host” emails on your domain for free in a simple way – they forward them to your own address. So I registered one Gmail account dedicated for this. But now what about the sending? For this, you can use the good old “send email as somebody else”. Even Gmail allows you to do that, after verifying you actually have access to the address. But it has a small issue: anyone could do this from their own server, and some clients might show alerts. Gmail itself shows via gmail.com too. Solution to this is DKIM signing – storing public keys in DNS is, in my opinion, pretty ingenious.

Ingress tools

Ingress is an augmented reality GPS game, where you visit places, connect them with links and draw triangles on a global map (this is a significant oversimplification). As this is a battle of two factions, both factions build some tools to gain tactical advantage. I have written some tools myself, but can’t show them publicly, because Opsec and some of them live on the border of Ingress ToS. If you want to see some of my more algorithmic code, reach out, I’ll be happy to show you some parts.

Rickroll disguiser

Probably my first complete project. A simple web app that lets you create URLs with fake Open Graph metadata, but redirecting victims to Youtube videos, troll pages, you name it.
