Senior Software Engineer at Nerava building AWS payments platforms with secure Stripe payouts and 130+ API endpoints.
United StatesWhat I'm looking for
At Nerava, I architected a FastAPI and PostgreSQL platform on AWS App Runner that supports 5+ production web apps and 130+ API endpoints. I built Stripe Express payouts with wallet locking, idempotent webhooks, withdrawal limits, and double-entry ledger patterns.
At Visa Inc., I designed, built, and deployed Push-to-Wallet, taking a greenfield payments product from architecture through production launch. I also supported enterprise data privacy and security work and migrated services to active-active.
At Air Experts, I built token-based authentication, role-based access control, and a secure payment portal. Earlier, at 7 Senses Labs, I defined architecture and security requirements for an edtech IoT product and developed middleware, computer vision, and voice-recognition software.
