Software Engineer · React & TypeScript
I build fast, accessible interfaces for complex products.
I'm a frontend-focused software engineer with 14 years of experience, from WordPress and PHP to React, TypeScript and Node. Today I work on large-scale digital platforms in Lisbon, with a focus on code quality, security and performance. I've led frontend work on real-estate and event platforms and set up CI/CD pipelines from build to deploy. I also build mobile apps with React Native and Expo.

About
I started building websites in 2009 and moved to React in 2016. I have worked remotely with agencies, startups and public institutions across Europe, as a freelancer and as part of product teams. I care about code quality, tests, accessible interfaces and delivery pipelines that make shipping boring.
