About Me

Developer with 6+ years of experience building production-ready systems. Currently a Senior Manager of Product Support Engineering at Donorbox, a US-based fundraising platform processing millions in donations for nonprofits worldwide.

On the side, I build applications as a freelancer for clients in Brazil and abroad — from healthcare systems to logistics platforms and AI-powered automation. My edge is a hybrid profile: deep technical expertise combined with leadership experience. I deliver pragmatic, scalable solutions — no fluff.
