Contributed to the development of responsive React/Redux merchant dashboard components and Java Spring Boot microservices with robust pagination, filtering, and validation. Optimized PostgreSQL/MySQL queries with indexing strategies to reduce latency, supported migration from monolith to Dockerized microservices, and implemented backend and API test frameworks to boost automated coverage. Deployed monitoring pipelines on Google Cloud Platform to improve incident response and collaborated on NLP-based chatbot and ML-driven storefront widgets to enhance user experience.

Developed scalable backend microservices with Spring Boot and Hibernate, built real-time data processing pipelines (Kafka/RabbitMQ), and deployed containerized apps on Docker/Kubernetes across Azure. Optimized SQL (PostgreSQL/MySQL) and NoSQL (MongoDB) queries, implemented automated testing with JUnit/Mockito and Postman, and collaborated with frontend teams to deliver responsive React/TypeScript UIs.

Developed scalable backend microservices using Spring Boot and Hibernate to handle 1M+ daily API requests with improved fault tolerance and uptime. Built real-time data processing pipelines with Apache Kafka and RabbitMQ, increasing data flow reliability and reducing pipeline failures by 40%. Designed secure API integrations with OAuth2/OpenID Connect, ensuring compliance with financial and healthcare security standards. Deployed containerized applications using Docker and Kubernetes, automating scaling and reducing production downtime by 27%. Optimized SQL (PostgreSQL, MySQL) and NoSQL (MongoDB) queries through indexing and caching, reducing average query latency by 45%. Developed automated testing frameworks using JUnit, Mockito, and Postman, achieving 90%+ coverage and reducing defect leakage by 35%. Collaborated with frontend teams to develop responsive React and TypeScript UIs, decreasing UI-related bug tickets by 30% and improving UX. Supported migration of monolithic systems to
