Principal Software Engineer @ Indeed · Dublin, Ireland 🇮🇪 · São Paulo at heart 🇧🇷
Generalist · builder · audiobook addict · wannabe photographer
Data enthusiast since 2010 — started in dev (C#, PHP, mobile), drifted into Business Intelligence and data engineering, and ended up back at full-stack software where I get to do all of it. Today I'm a Staff Software Engineer at Indeed and a chronic side-project builder.
I write things I can't find: a TUI for my brokerage, an LLM pipeline that translates my favourite book series, a docs platform that understands your topology, an audio recorder for Obsidian that doesn't suck. Most of it is open source and lives below.
