About

I am a Software Developer at Microsoft (RiskIQ, Microsoft Security). I did my Master's in Computer Science with a specialization in Artificial Intelligence from Northeastern University, Boston. Previously I worked as a Backend developer for four years on Search, Data platforms, and Competitive Analytics teams. I primarily worked on projects based on Java, with Spring being the framework of choice. I also worked on a few front-end projects using React and Redux for a short time.
