About me

Software Engineer

Hi, my name is Kevin Koster. I'm a 24 year old Software Engineer based in the Netherlands. I work across front-end and back-end systems, helping teams ship awesome products, features and maintainable codebases.

Experience: 5+ years
Current role: Software Engineer @ Realtime Register
Focus: Full-stack

What I care about

Building digital products that feel clear, useful, and easy to maintain.

I like shaping systems that are pleasant for both users and teams: interfaces that feel intentional, codebases that stay readable, and delivery processes that don't create extra chaos.

That often means moving fluidly between UI details, architecture decisions, and the small cleanups that make future work faster.

Strengths

What I tend to bring to a team.

Strong front-end implementation with design sensitivity
Practical back-end experience in Python
Comfortable owning features from interface to delivery
Calm collaboration across product, support, and engineering
Momentum through refactors that reduce long-term friction

Experience

A quick path through the work so far.
