About Me

Building Real-Time Robotics Systems

I'm a Robotics Software Engineer with 3+ years building real-time, multithreaded C++ systems, robot task lifecycle state machines, and fleet-level coordination software for autonomous robots.

My background spans deterministic motor control, behavior trees (BehaviorTree.CPP), ROS2/Nav2 navigation, and backend services built on gRPC, RabbitMQ, and MongoDB. I hold an MS in Mechanical Engineering (Robotics & Dynamics) from IIT Madras.
