I build products end to end: architecture, web and mobile apps, and the product decisions in between.

16+ years building with React, React Native, Node.js, TypeScript and .NET, from enterprise integrations to a platform with 400+ microservices.

Hands-on, from architecture to app store.

16+ years building software: .NET enterprise integrations, web and mobile apps for a US client, the core technology team at Infocorp, and my own product, Adme.

I start by analyzing the problem, then design a solution that fits the time, team and infrastructure available, following established patterns and defining new ones when the context requires it.
