At Nerv3, I helped build the core backend of a nationwide platform from the start to 150,000+ active users, supporting onboarding, document review, payments, refunds, printing, and shipping. I co-designed idempotent PIX charges and refunds that remain correct through retries, concurrency, and lost provider webhooks.
I also designed and built both sides of a scholarship platform now in production: a NestJS REST API and worker, a Next.js front end, digitally signed contracts, and contract-first OpenAPI integration. On my personal projects, I built an AI assistant for live property data and a medical exam-prep platform; before software engineering, I founded and ran PH Distributor.
