Architected microservices using Java and Golang powering high-traffic backend workflows serving millions of daily users. Designed low-latency inter-service communication using Spring Boot (REST) and gRPC, improving request throughput across distributed services. Built Kafka-based event-driven pipelines handling real-time async processing for large-scale user journeys. Reduced P95 API latency by ~40% through Redis caching and pagination strategies on high-traffic endpoints. Designed DynamoDB and PostgreSQL data models supporting 10M+ daily active users, optimizing for high-throughput read/write workloads. Scaled campaign processing from ~200 → 10,000+ concurrent entities using idempotent job orchestration with exactly-once execution guarantees. Led production excellence — CI/CD pipelines, on-call rotations, RCA for incidents with minimal user impact.

Improved fraud detection accuracy by 20% by developing a custom transaction recovery service. Reduced system downtime by 30% through a real-time monitoring dashboard built with Spring Boot and automated Linux scripts. Modernized legacy infrastructure by migrating an AngularJS application to Angular 18, improving frontend scalability. Strengthened platform security by integrating Multi-Factor Authentication (MFA), while simultaneously optimizing the flow to save 2–5 seconds of user wait time. Optimized data retrieval for over 5,000 daily transactions using VPA and account-based search enhancements.
