What I'm looking for

I’m looking for a role where I can build scalable backend systems in microservices, own AWS infrastructure, and improve reliability through testing and CI/CD—while continuing to grow as a full-stack and system-design engineer.

I’m a Member of Technical Staff - I at Nielsen, where I design and develop scalable backend services with Java and Spring Boot. I built 25+ RESTful APIs in a microservices architecture, implemented WebSocket-based service-to-service communication, and used AWS SNS for event-driven workflows—cutting inter-service latency by 40%.

I also deliver customer-ready features end-to-end, building full-stack capabilities with React.js and TypeScript and shipping 15+ production features. I focus on reliability and efficient delivery through TDD (85%+ test coverage with Mocha), stronger CI/CD automation (Playwright, Selenium), and AWS infrastructure ownership (EC2, S3, DynamoDB, Lambda, CloudWatch) to reduce manual effort and improve system resilience.
