Summer 2025
Software Development Engineer Intern @AWS (During MS)
During my Master's program, I interned at Amazon Web Services in Seattle, where I integrated Java-based long polling in DynamoDB microservices to reduce redundant requests. I evaluated multiple design approaches for scalability and growth, and optimized concurrency with configurable timeouts and async request-reply patterns. This work resulted in an 84% reduction in total requests, significantly lowering CPU usage, memory consumption, file descriptor usage, and network I/O.
