Adept problem solver, self-starter, and curious engineer with a love for concurrent,
scalable, resilient, and cloud-native software. Demonstrates a proven record of success in
leading engineering teams, simplifying processes, and managing multiple projects
delivered on time. Possesses exceptional communication skills.


Worked on a Neural network approach to adaptive
beamforming for millimeter-wave systems for my final year project. Used the ML model for time-series prediction of vehicle motion along a  road segment and a beamforming algorithm for adjusting the antenna beam to match the predicted vehicle motion.
