> Software engineer based in Barcelos, Portugal. I build products and tools around language models, agents and automation — and I write about it. This site is an operating system: an iPhone on mobile, a Mac on desktop.

I'm Hélder. I build software — and, more and more, software with language models inside it: agents, MCP servers, and automation that saves real people real work.

By day I work at Bitsapiens on systems that connect people, data and AI. The rest of the time I build my own things: an MCP server that reads the macOS Stocks app, a bridge to steer Claude Code from a Garmin bike computer, a bot that turns community chat into a product backlog. Almost all of it open source.
