More About Me

HELLO! I AM TOM MEIJER

A software developer with over 10 years of experience.

I am a driven and positive-minded person who enjoys solving problems through technology. I’m fascinated by software development and everything that comes with it. What I find most rewarding is seeing all the pieces come together into a working product, something that truly benefits people.

I like working in a team and have an open communication style. I’m also a good listener when it comes to understanding clients’ needs, and I can quickly translate those into technical requirements. Additionally, I find it important to stay up to date with the latest standards and technologies – because standing still means falling behind!
