What I'm looking for

I want to build product-focused software with strong engineering practices—React/GraphQL, clean APIs, and thoughtful UX—while pushing into AI-driven, intent-based interactions and contributing to open-source culture.

I’ve spent the last 20 years building web products for both startups and large organizations, including Globo.com. I’ve worked across the full stack, mainly with React, Node.js, Ruby, Python, and GraphQL, and I enjoy moving between product thinking and technical implementation.

As a senior engineer and front-end lead, I’ve shaped architecture decisions, built reusable UI components, and delivered complex data visualisations while improving user experience and performance. I’m active in open source, have spoken at international conferences, authored Mobile First Bootstrap, and I’m the founder of Gitpay—now I’m also exploring AI in software development through intent-based, conversational experiences.
