At Cognizant, I design, develop, and deploy scalable RESTful APIs using Java and Spring Boot within microservices architectures. I support high-throughput communication between front-end and core backend services.
I've implemented real-time asynchronous processing with Apache Kafka and Spring Boot, reducing latency for large-scale data ingestion streams by 20%. I also integrated AWS services and Amazon SQS for deferred execution and background workflows, improving availability and reducing peak-load API response times by 150ms.
I work on PostgreSQL and MySQL schema design, database-integrated APIs, connection optimization, and CRUD performance. I also integrate third-party payment and authentication APIs with fallback patterns and structured logging to improve resilience and root-cause analysis.
Previously, I resolved production incidents, containerized services with Docker, and partnered with product managers and frontend engineers in Agile delivery. I also built Shopzen, a distributed e-commerce backend using Spring Cloud, RabbitMQ, Redis, and a Trie-based product autocomplete system.
