What I'm looking for

I’m interested in international remote opportunities with product teams that value ownership and close collaboration between engineering and users.

At APM Help, I built SmartBill, a Python automation that has processed 85,000+ bills across 16 companies. It uses AI/OCR extraction, database validation, and duplicate detection to replace manual bill-data entry.

I also developed Sidekick, a Flutter and Go conversational interface for property managers, and created a training environment with 30+ reproducible accounting scenarios. The platform trained 50 employees in its first month and cut learning time by 50%.

At Foxbit, I defined the Flutter architecture and helped drive the mobile app’s incremental migration. I contributed to improvements that raised its app-store rating from 2.8 to 4.5, and helped the application reach 99.85% crash-free sessions over a one-month period.

I’ve worked across mobile applications, backend services, and automation in fintech and US property management. I’m based in Brazil and interested in international remote opportunities with product teams that value ownership and close collaboration between engineering and users.
