Lead Frontend Developer & Trainer

Crafting experiences,
not just interfaces.

I've been building web products for over 20 years, scaling from small projects to enterprise-level platforms at companies like Vodafone and Ogury. The journey from VB6 → PHP → .NET → Frontend wasn't linear — but every step sharpened both my technical craft and my curiosity.

Today I lead frontend teams, architect scalable React systems, own CI/CD pipelines, and run the full lifecycle from discovery to deployment. I'm equally comfortable writing code, reviewing PRs, running SCRUM ceremonies, or sitting in a pre-sales discovery call.

When I'm not shipping product, I'm training developers — because the fastest way to grow is to teach what you know.

I build the things people actually use
and I teach others to build them even better.

Twenty years of building software has taught me that the best work happens when technical rigour and genuine curiosity pull in the same direction. I care about the gap between a good idea and a working product and just as much about sharing that process with the developers around me.
