I'm a full-stack software engineer/developer/architect since 2000. Worked in several large projects in many different roles, but nowadays I prefer the smaller scale.

A freelance consultant with an interest in usability, business analysis and getting the right stuff done. Opinionated, but platform agnostic. Familiar with several programming languages, tools and environments. Learning more as I go.
