Resume


Hello! My name is Matěj and I’m from Tábor, Czech Republic. This May I graduated from high school and I’m continuing my studies of Computer Science at the Faculty of Mathematics and Physics at Charles University in Prague. I’m currently employed at the Czech startup Apify in the role of a Node.js engineer / Web Automation developer.

Here you can find a showcase of my previous work and what technologies I enjoy working with. Apart from my current job at Apify, where I’m enjoying the possibility to work with and learn from experienced engineers with many different expertises, when I was at high school I worked on several projects of my own and I also made a few minor contributions to various open-source projects.

Work experience

Node.js engineer at Apify Node.js, Web scraping June 2022 – present

My entry job into the world of real-world IT. It's not the time to fully reflect on this job yet, but so far I'm really enjoying the opportunity to learn from experienced engineers, from platform DevOps managers to front-end engineers to senior web automation devs. The open and free company culture allows me to get maximum insight and learning opportunities at this position.

Projects

RoboRally game, web, Svelte, Rust, WebAssembly March 2022

As my high school graduation project, I recreated the board game RoboRally as a multiplayer online game. This included a backend written in Rust, WebSocket transport layer, Rust compiled to WebAssembly for game state deserialization and a highly interactive Svelte frontend.

Evavolfova.cz web, Svelte, frontend, deployment 2018 – present

Since 2018, I've been maintaining my mother's website (and eventually also a small e-shop). The first version was a simple static website generated with Frozen-Flask. However, as the scope increased (and my skills improved as well) , a frontend framework became necessary, so the website is currently written in SvelteKit.

With this project, I also learned a lot about how to manage a full VPS – while the app itself still runs on Netlify (I intend to move it away as soon as I find a better CMS + asset handling solution), I'm self-hosting Caddy, Plausible analytics and a Postgres database in a Docker-compose cluster. I've also setup Grafana with alerts to monitor server load etc.

Python mailmerge scripting, Python August 2021

One of the smaller projects of mine. When Google introduced security changes that prevented my favourite mailmerge add-on from working, I decided to write my own batch mailing solution in Python. The script uses front-matter for metadata, and Markdown + Jinja for email body.

My favourite feature is the possibility to triple-check everything – unless you opt out, you get a preview of each email (both plaintext and HTML), and you can even fake-send all emails to your own address to check attachments etc.

Ingress tools Python, algorithms May 2020 – January 2021

Ingress is an augmented-reality GPS game, an ever-lasting battle of two factions. The game provides an online real-time game map, and each faction develops its own, private set of tools that operate on the game data and facilitate planning and monitoring operations. One the tools I created helps with preparing efficient game plans.

For tactical advantage, the code isn't public, but I'll be happy to present some parts of it if you reach out.

Bakatasklist web, Python, Flask, PostgreSQL March 2020

A web app for better management of homework.

During the first wave of COVID-19 lockdowns in March 2020, homeschooling for many students at my school became a mess. Teachers were assigning us homework using Bakaláři (system commonly used by Czech schools), but the program worked with completely different assumptions and absolutely wasn't prepared for homeschooling. Therefore I created Bakatasklist to allow importing assignments, viewing them in a sortable table and manually marking finished/unfinished assignments.

Unfortunately, the API I used for importing homework was replaced a few months later. I planned to create a second version which would use the new API and also allow importing from other systems including Google Classroom, but all the schools systems rapidly improved, and we went back to schools before I was done, so it was never completed. Stub of this project is, however, available to see.
