I build scalable backend APIs and resolve production issues across distributed systems.

India
Message

I've built and supported scalable backend systems across PeopleStrong, Oodles Technologies, and full-stack engineering projects. At PeopleStrong, I investigated high-severity production incidents across application and database layers, delivering permanent fixes that reduced recurring escalations by 40%.

At Oodles Technologies, I developed RESTful APIs in a microservices architecture using Node.js, PostgreSQL, and Sequelize, improving API response time by 20% while supporting 10K+ monthly transactions. I also worked alongside Java/Spring Boot teams on API design, debugging, testing, and distributed-service integration.

I'm comfortable taking systems from design through delivery: building CI/CD workflows with Docker, Jenkins, and Kubernetes; automating API testing; and improving test coverage by 65% while reducing regression issues by 35%.

My projects include DPIEngine, a Java and Spring Boot traffic-classification backend with Redis-backed session tracking and rule-based filtering, and SwiftRoute, a logistics platform with JWT authorization, transaction-safe order assignment, and documented REST APIs. I also built Sortify, an interactive sorting visualizer using React and Web Workers.
