About

I’m a Software Developer (SDE-2) with 3+ years of experience building scalable backend systems and high-performance APIs using Java, Spring Boot, microservices, and cloud-native technologies. At Oracle (Primavera Cloud), I led the development of multiple REST APIs for file operations (zip/copy/download/upload) and improved key workflows by optimizing algorithms and performance — including accelerating folder deletion by ~30%. I also solved high-impact production issues by deep troubleshooting and cross-team collaboration, including reducing login time from 2 minutes to ~1 second for affected customers (award-winning fix). Recently, I worked on an AI-driven initiative where I designed a new microservice for semantic file search by integrating OCI Generative AI models and vector search (Oracle SQL 23ai), enabling retrieval of the top relevant files based on semantic similarity. At Zeta, I contributed to enterprise B2B card management APIs and significantly improved reliability and performance of the card creation workflow — reducing API P95 latency from 4s to 300ms, cutting workflow P95 from 1 min to 10s, and bringing failure rate down from 14% to 0%. I enjoy owning end-to-end delivery, building systems that scale, and solving hard backend problems involving performance, reliability, distributed workflows, and AI integration. Tech Stack: Java, Spring, Temporal, REST APIs, SQL, Kafka, Docker, Kubernetes, OCI/AWS, ELK, Grafana, Jenkins, Microservices.
