Hi, I'm Muhammad Raahim Khan 👋

Working as a Senior Software Engineer (Full Stack) and building features for fleet safety products end to end, from frontend to backend APIs. Shipped the AI speed sign detection feature across the web dashboard and backend, lifting detection accuracy from 95% to over 98% for enterprise fleets. Took full ownership of the speed limit editor, refactoring its state management and building the interactive route planner on top, eliminating a class of bugs and reducing support tickets. Stepped in under resource constraints to drive the speeding over policy feature to completion, covering company and vehicle config, events, alerts, and behavior endpoints. Also resolving map UI performance issues, writing unit tests, leading code reviews, fixing production bugs, maintaining owned features, and serving on the on call rotation to keep releases stable and customer impact minimal.
