What I'm looking for

I'm looking to own end-to-end development of scalable systems, from architecture and backend services to frontend delivery, especially in fast-paced product teams.

I've owned end-to-end product development at NymCard, Moback Technologies, and BorrowBe, building financial infrastructure, HR-tech backend services, and a rental marketplace platform. At Moback, I designed internal routing that reduced inter-service latency by up to 70% and overall latency by up to 40% in certain cases.

I'm comfortable taking systems from design through backend, frontend, database, and production deployment. My work includes Stripe-integrated wallets, real-time chat and notifications, approval-rule engines, WebSocket-based 2FA and audit logging, multi-gigabyte streaming exports, and AI-integrated RAG workflows.
