At Fortis, I design APIs and integrations for 20+ fintech services across merchant onboarding, payments, subscriptions, access management, and reporting. I've designed payment flows with Network International and MyFatoorah, plus onboarding and sign-in platforms using Temporal, Keycloak, OTP, Google Sign-In, and 2FA.

Over 13+ years in systems analysis, including banking and fintech roles at LIFE PAY and Sber, I've shaped high-load distributed services, legacy migrations, and OpenAPI-first integration contracts. I work across REST, Kafka, PostgreSQL/JSONB, system design, and production delivery, and use AI coding agents for Python implementation, debugging, testing, and refactoring.
