Key Achievements
- I process 10,000+ daily banking jobs via a multi-trigger Azure Function App (HTTP, queue, time triggers), ensuring safe execution with SemaphoreSlim and distributed locks.
- I engineered payments and back-office features using CQRS and event-driven patterns with idempotent command handlers to prevent duplicate financial processing.
- I integrated OAuth 2.0 and JWT-based authentication, applying RBAC middleware and Azure API Management for centralized access control.
- I maintain PCI-DSS compliance through meticulous event trails, data consistency checks, and transactional integrity across high-scale financial services.
- I enhanced platform observability using OpenTelemetry for distributed tracing, alongside xUnit integration tests and circuit breaker patterns.
