A bit about me...

Hi, my name is Mikolaj, and I'm a 4th year BSc (Hons) Computing student focused on Software Engineering, Full-Stack Dev and tinkering with hardware. I'm passionate about building clean, efficient software that solves real problems and delivers a great user experience.

I started coding in secondary school with Python and Micro:bit. Since then I've grown through personal projects, real-world experience and coursework, working with modern web frameworks like Next.js and Angular, desktop development with C# and WPF and recently gaining experience with Java, Spring Boot and tools such as Datadog, Temporal and DBeaver.

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.
