About

With gratitude for the enriching experiences that have shaped my career, I've had the privilege of spearheading the development of mission-critical systems for renowned tech giants. My expertise spans the full stack, encompassing the creation of ML/DL models, ML modeling platforms, frontend applications, and backend microservices capable of scaling to over 1 million queries per second. Additionally, I have played a pivotal role in architecting infrastructures and platforms that support and empower other engineering teams. Throughout various roles, I've actively participated in committees dedicated to steering the technical trajectory of organizations. Always driven by a passion for continuous learning, I am particularly intrigued by deep learning particularly and most recently Graph Neural Nets.
