Piotr Gałka

Fullstack Developer · .NET · Next.js

I build web apps that are reliable and cheap to maintain.

Focused on the .NET + Next.js ecosystem, readable and scalable code. I look for the sweet spot between clean code and pragmatism — without overengineering. I'm driven by technical challenges, pushing boundaries and those "aha!" moments when everything clicks into place.

Education

Humanitas University, Sosnowiec

Oct 2025 — now

Psychology — Master's degree

I chose Psychology to complement my technical background with a deeper understanding of human behavior. Stepping out of the purely logical world of programming sharpens communication and empathy — essential in collaborative work.

School of Electronics & IT

Sep 2019 — May 2024

Software Development Technician

I used the lockdown period to independently master the fundamentals of programming. Before the era of AI assistants — through hands-on practice, building my first full-stack apps with Python (Flask) and React.
