The freelancer

A software
craftsman.

An independent developer for over 20 years, I help companies, freelancers and founders turn an intuition into working software — reliable, readable and built to last.

I believe good software is measured by what it lets you forget: the tech.

No over-engineering, no hype-driven choices. I pick proven tools, write clear code others can pick up, and always keep in mind the person who'll use the product every day.

My strength: you work directly with me, the expert, at every step. No middleman, no project manager relaying to a junior developer.
