Hi, I'm Raphael.
I build software that moves things forward.

Based in Portugal, I'm a software engineer who builds products end to end — databases, authentication, front-end — and the AI agents and automations that run them. I architect features and integrations for product teams, and design AI systems that remove manual work for businesses. Read a bit more about me.

What I Do

For product teams

I act as a technical partner: architecting new features, integrating external services, and translating business goals into scalable software. Whether it's a full-stack application, an AI-powered agent, or a complex API integration, I focus on shipping software that works in the real world.

For local businesses

I design and build automation workflows using tools like n8n, Make, LangChain, FastAPI, and Voiceflow — integrated with third-party APIs and custom logic. I connect systems, eliminate manual work, and create pipelines that run on their own — so teams can focus on what matters.

My goal is straightforward: write good software, automate what slows you down, and help your product move forward.
