Hello there!

I’m Mateusz, a passionate Fullstack Developer. When I’m not cycling or gaming, you’ll find me diving deep into TypeScript generics or optimizing applications performance. -- This application is powered by Next.js and PayloadCMS, running within a Dockerized environment on my Oracle Cloud VPS (Ubuntu). It’s exposed to the web via nginx, enhanced for speed with Cloudflare and monitored using Plausible.
