A bit about me...

Hi, my name is Mikolaj, and I'm a 3rd year BSc (Hons) Computing student focusing on full-stack web development and desktop applications. I'm passionate about building clean, efficient software that solves real problems and delivers great user experiences.

I started coding in secondary school with Python and Micro:bit. Since then I've grown through personal projects and coursework, working with modern web frameworks like Next.js and Angular, and desktop development with C# and WPF.

Hobbies

Motorsport & Cars

Chairperson of the college Motorsport Club. Providing members with go-karting trips, game events, and car meets - building a community around a shared passion.

A strong passion for cars drives me to work on mine and others' vehicles, building experience and a deeper appreciation for the engineering and skill involved.

Tech

Around tech since I was young - gained knowledge of hardware and electronics from my dad. I've built, serviced and repaired multiple PCs, laptops and devices for myself and others.

Recently switched to Linux (Fedora Workstation) via dual-boot and enjoy tinkering to learn the differences vs. other OS'es.
