About

Over a decade building production systems across backend, web, and mobile. Currently at Trade Republic on the Cards team, maintaining an internal Swift Macros library that has eliminated more than 40,000 lines of boilerplate. Previously three years at Blinkist on a product reaching millions of readers.

a7t is the side practice. The numerogram covers five categories the projects here tend to land in: assistant, archivist, architect, autopilot, and autoagent. Jano is the local-first LLM router and queue. Three-Body Agent is an autonomous development pipeline that picks issues from a GitHub project board, implements them via Claude Code (or any LLM provider), fixes its own CI failures, and merges green PRs. Poirot is a native macOS companion for investigating Claude Code sessions. The full set lives on the projects page; the source lives under github.com/a7t-ai.

If you'd like one of these wired into your stack, or a system spec'd from scratch, the booking page is the way in. Sessions in English or Portuguese.
