ABOUT ME

Senior JVM/Backend/Cloud engineer, programming since 14yo

Together we are better!

In everything I did I was always helping out with programs, websites, advice. From 14 years old me working on programs for the first MS PocketPC, to airport and food delivery platforms and government institutions: I hope to bring value everywhere I go. Business value for customer. Help colleagues grow. Business value for employer.

Don't stop end of day with the task at hand, but see the big picture, be ready to help things grow. That's me.

I try to combine wide software engineering knowledge, business insights and team power into something realistic and practical.

I am flexible in hours, not so much into travel for work. Can you match that?

Programming in Java is something I do since University. I know my way around that landscape like the back of my hand, building backends, fullstack apps, APIs. I'm not a low-level data structure/algorithm guy, I know how to get the big parts in your project moving fast and/or automatically!
