Notification Micro-service
Engineered and optimized high-performance, containerized microservices for a critical notification platform, leading architectural upgrades (e.g., httpClient 4.x to 5.x) and implementing dynamic rate limiters, resulting in substantial performance gains and enhanced service scalability within a distributed architecture.
Designed and delivered a secure, asynchronous, and extensible notification payload transformation service, leveraging event-driven patterns (Redis for queuing), Java, and a Node.js transformer sidecar for flexible processing of untrusted user code, significantly increasing service flexibility and security.
Pioneered real-time user engagement capabilities via WebSocket-driven in-app messaging and the Fusion Bell notification channel, improving responsiveness and user experience in a loosely coupled system.
Drove significant improvements in software quality and reliability by spearheading initiatives that increased unit, integration, and end-to-end test coverage to over 85% across critical microservice components, reducing technical debt and accelerating release velocity.
Enhanced system observability, operational resilience, and security through distributed tracing (spans), Prometheus metrics, improved reporting, and architectural modernization (JPMS integration, Helm-based service orchestration, establishing private network scopes for inter-service communication, and developing robust authorization mechanisms for public-facing API gateways).
