About

Over a decade building production systems across iOS, Swift, Rust, and Python. Currently at Trade Republic on the Cards team, where my Swift macros library SwiftMockKit has removed over 1,100 mock files and about 91,000 lines of generated boilerplate. Before that, three years at Blinkist on a product that reached millions of readers. I also speak about this work; the recent talks are on the talks page.

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 contact page is the way in. English or Portuguese both work.
