About

Software Engineer with 4+ years of experience in building scalable, high-performance systems in the fintech domain using Java, Spring Boot, Microservices, and Kafka. I specialize in designing distributed systems, optimizing performance (up to 80% improvement), and building resilient applications using Circuit Breaker and Retry patterns (Resilience4j). I have worked on production-grade financial systems with a focus on scalability, reliability, and security. In addition to backend development, I have hands-on experience with React.js (Hooks, Redux, Context API), enabling end-to-end feature delivery by integrating frontend and backend systems through REST APIs. Key Highlights: * Built and optimized microservices using Spring Boot, WebFlux, and Kafka, improving scalability and data processing efficiency * Developed high-performance APIs, reducing response times by up to 40–80% * Implemented automation and integrations (Gmail API, Tally, financial APIs) to streamline business workflows * Experience with CI/CD (Jenkins), containerization (Docker), and AWS (EC2, ECS, S3, IAM, API Gateway) I enjoy solving complex engineering problems and building scalable systems. Open to opportunities in backend and full-stack development roles. Let’s connect.
