About

I own delivery end to end, from architecture and database design to Docker, CI/CD, and cloud (AWS, GCP, Azure). My backend core is PHP/Laravel, Node.js, and Python on PostgreSQL, with Vue and React on the web and Flutter on mobile.

I hold an MBA in Data Science from USP, Brazil's top-ranked university, and have shipped ML models and LLM automations to production. I co-founded and was CTO of an influencer-marketing startup accelerated by Rede Globo's Grupo Mirante, grown organically to 10,000+ users.

I also build my own products, and I care about the unglamorous parts: SEO, onboarding, billing, and keeping things running.
