About

I started programming at the age of nine. Now, almost four decades later, I've worked in banking, telecommunications, healthcare, flower auction and many more. I am bringing soft and hard skills.

I'm a polyglot, learned around 30 technical languages for markup, scripting and programming. The love for tech makes me a perfectionist, but I also read the room, and navigate between the best and the possible. I have done many programming jobs, with or without automated testing.

I have also had people-jobs, lead functional desiger, coached a Team to improve their Agility and quality, acted as mediater in a dispute between very technical actors to further an architectural decision, helped a scrum-team in the adoption of new serverless technology.
