At Time x Mart, I built the Java Spring Boot and Vue 3 system for a peer-to-peer marketplace where people swap help. I designed its negotiation flow to prevent concurrent updates from booking the wrong deal, and added load shedding so browse and search can fail before trades.

At Amazon Web Services, I designed OpenSearch query-engine and dashboard features, including hot-shard routing that cut mean latency by 45% and p99 latency by 62%. I also built Specter, a Python text generator using PyTorch and vLLM that ran 2.36x faster idle and 1.63x faster under load.
