// About
// What I do
I am an 18-year-old software developer and systems enthusiast. My main focus lies in writing clean backends, developing custom web applications, and hosting systems, with a secondary passion for hardware microcontrollers and electronics. When I am not writing code, I am out jumping dirt bikes.
Writing clean code and automating deployments—whether it's custom scripts, database engines, or virtual nodes—I make sure web applications stay reliable, fast, and secure.
01
Web & Backend
Custom web applications, clean PHP and JavaScript backends, and database design — built to stay fast and maintainable.
02
Hosting & Infra
Self-hosted Linux servers, Nginx reverse proxies, Docker workloads, and automated SSL — deployments I actually run.
03
Hardware & Electronics
ESP32 and Arduino controllers, custom PCBs, and simracing button boxes — from schematic to printed enclosure.
