Message

At Citicorp ( Citi Bank ), I’m leading development and enhancement of the Market Risk Analytical Calculation Engine, which processes 10M+ records daily for risk measurement and reporting. I work with risk analysts and business teams to implement solutions, and use Python, FastAPI, and AWS in the project.

Previously, at Xplor Technologies, I led end-to-end development and feature delivery for a payment gateway covering authorization, capture, settlement, and refunds. Across other roles, I developed APIs for a real estate platform and features for research, publication, and online quiz applications.
