Backend Engineer at Hablla, a conversational marketing company and Meta BSP, with a strong product focus. I work mostly on data aggregation pipelines in Go and integrations with the Meta APIs (WhatsApp Cloud API, Instagram, Facebook): designing the architecture, keeping the product running and making sure the numbers it reports are right.

Lately I've been building a lot with and for AI agents: tools agents can use, with deterministic cores and measurable results.

B.Sc. in Computer Science from UNESP, where I did research in parallel and distributed systems and NLP.

“There is no path. Beyond the scope of light, beyond the reach of Dark…
…what could possibly await us?
And yet we seek it, insatiably…
Such is our fate.”
