India

Message

At Bank of America, I engineer Python and PySpark data pipelines on Quartz Risk Engine and release model workflows to Azure for financial transactions. I also build REST APIs and WebSocket services for enterprise request processing.

I maintain ML services on Azure, deploy containerized applications with Docker and Kubernetes, and improved numerical execution latency by 35% through NumPy vectorization. I automated validation frameworks that achieved more than 88% test coverage.

As a College Lecturer at SBITM, I taught computer science coursework and mentored student projects. In independent projects, I built a Python backtesting engine and a speech recognition system using C++ and React.js.
