About

Experienced Backend Engineer with 3.5 years of hands-on experience in designing and developing scalable microservices using Java (Java 8/11/17/21), Spring Boot 2.x/3.x, and RESTful APIs. Skilled in system design, database modeling (MySQL, MongoDB), event-driven architecture using Kafka, and caching strategies with Redis. I’ve led multiple end-to-end backend initiatives, including building new microservices from scratch, integrating third-party systems, and optimizing performance-critical components. Proficient in debugging complex production issues, implementing retry mechanisms, and ensuring system reliability with observability tools and alerts. Passionate about clean architecture, design patterns, and writing maintainable, testable code that scales well in high-traffic systems.

Building backend in lending products
Designed and developed a new microservice using Java 21 + Spring Boot 3.x for insurance backend, handling system design, API contracts, and DB schema (MySQL) independently.
Implemented backend-driven dynamic UI rendering using service factory and customization strategy pattern based on partner and insurance type.
Introduced retry schedulers, application stage tracking, and dashboard-first flow for stateful insurance applications.
Fixed delayed message processing in Redis-Kafka queue by configuring Redis with notify-keyspace-events Ex to enable key expiration event triggers.
Resolved high CPU usage in a microservice by identifying Kafka consumer rebalancing as root cause and optimizing configs like max.poll.records, session.timeout.ms, and heartbeat.interval.ms.
Ensured idempotent processing, improved Kafka backpressure handling, and stabilized consumer group performance by tuning concurrency according to partition count and by segregation of groupId for major consumers.
