About

Java Backend Engineer specializing in building high-performance, cloud-ready microservices using Spring Boot, Java 17, and Kafka. I deliver backend systems that scale to millions of users, optimize API performance, and power mission-critical enterprise platforms. At Cognizant, I modernize complex healthcare applications for Kaiser Permanente—migrating legacy systems to microservices, improving response times, securing APIs with Apigee + OAuth2, and optimizing Oracle/PostgreSQL pipelines for 12M+ member records. I own backend delivery end-to-end, from architecture to production stability. Driven by clean architecture, distributed systems, and performance engineering, I build backend services that are fast, reliable, and built to scale.

Kaiser Permanente
🔹 Built and optimized Spring Boot 3.x (Java 17) microservices to migrate a legacy Spring MVC monolith into a scalable, modular, and cloud-ready architecture.
🔹 Developed high-performance REST APIs integrated with Apigee Gateway and OAuth2, improving API response times through caching, indexing, and backend tuning.
🔹 real-time data processing workflows on Oracle 12c to efficiently handle 12.5M+ member records in a high-traffic healthcare environment.
🔹 Improved backend throughput by optimizing PL/SQL queries, refining transactions, and reducing latency under heavy concurrent user load.
🔹 Implemented CI/CD pipelines using GitHub Actions for automated build, testing, security scans, containerization, and deployment to Azure Kubernetes Service (AKS).
🔹 Designed containerized deployment workflows using Docker + AKS, ensuring seamless rollouts, efficient scaling, and zero-downtime releases.
🔹 Integrated role-based access control and secure authentication flows with OAuth2 and Apigee, strengthening system security and compliance for sensitive healthcare data.
🔹 Owned complete backend lifecycle: microservices architecture, development, production support, performance optimization, log monitoring, and defect resolution.
