India

Message

At OneCent Labs, I built and operated a real-time routing and transaction-processing engine that handled $1.6M+ in live volume. I reduced worst-case response latency 7× by pruning candidate paths, parallelizing work, and optimizing asynchronous execution and connection pooling.

At GlueX Protocol, I built asynchronous Python/FastAPI services and data pipelines integrating 55+ external sources. I also built VibeDeploy, a self-hosted deployment and AI-agent security platform, and a distributed SQL query engine for Parquet files in S3/MinIO.
