About me

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.

location:    Dublin, Ireland
origin:      São Paulo, Brazil
languages:   [Português (native), English (fluent), Bash (it counts)]
loves:       [LLMs, terminals, self-hosting, on-device ML, knowledge graphs, pão de queijo]
philosophy:  "Don't delegate understanding."
