Deep experience with payment integrations (Razorpay, Stripe, BillDesk, Cashfree), app security (ECDH, SSL pinning, FreeRASP), and the full app lifecycle from development to App Store and Play Store publishing. Mentored junior and mid-level developers through code reviews and drove coding standards across teams.
