Having my own TrueNAS Scale server at home, I've self-hosted multiple apps and projects, including Nextcloud, Immich, Gitea, Prometheus+Grafana, ngIRCd, WireGuard Easy, and many more.

I route them all through my Caddy reverse proxy, but since my server is behind NAT, I also have a VPS that is connected to my server through a tunnel and routes all of the traffic to my server through that tunnel.

I also protect myself against data loss with a RAIDZ1 ZFS pool, regular backups (monthly to an off-site physical drive owned by me and every two days to a cloud storage box), and regular ZFS Scrubs.

And everything is encrypted, my pool and both backups with a randomly generated binary file.

Needless to say, I've got some experience with system administration as well as Linux systems, since I also daily drive Arch Linux.

Some of my projects:

Name	Description	Tags
SOČ 2024/2025 Paper	Research paper entitled "Faktory ovplyvňujúce študijné výsledky a identifikácia rizikových skupín", which won first place in the regional round of the competition	#statistics#research
State SOČ Cross Examination	Cross examination of the Slovak State SOC Competition results and the analysis of the judges' bias	#statistics
Door alarm	A home-made door alarm based on ultrasound sensor distance measurements (in development)	#electronics#go
Green School / Zelená Škola	A website for a school club of environmentalists	#web-dev#nuxt
Automod	A discord bot for my local community	#discord#kotlin
Pwetty	A very, very simple json prettifier	#c#assembly

Antifed	A system to run actions in an emergency, like a fed raid	#kotlin#android
Adventná Výzva	An interactive game-like app for kids with an advent theme	#web-dev#react

And many other closed-source projects, especially contracts (like NatArt) and the tens of projects at FEI STU (including multiple algorithms and labeling / data processing systems, mostly concerned with bio-medical signals like ECG or PPG).

About me and my interests:

I spend most of my free time working on various projects of mine; I've recently decided to expand my horizons and work on some projects that are not pure computer science. But other than that, I like to go on walks, listen to music, and I occasionally play video games.

I also love going rollerblading and I used to play airsoft, but I haven't had the time to play recently. And, believe it or not, I like to cook and read books as well.

When I grow up, I want to study mechanical engineering, since I take interest in engineering in general, not just programming. I'm still not sure which university I want to go to, but chances are that it will be somewhere in Germany, Benelux, or Scandinavia (or Czechia and Slovakia as a last resort). Both my parents are successful engineers (chemical, not mechanical though), so I have a lot to live up to.

But currently, I'm just trying to survive high school.
