About

Senior Software Engineer with ~5 years of experience building high-scale, performance-critical web and video platforms. At PhysicsWallah, I worked on core video and real-time infrastructure powering large-scale learning experiences. My work focused on building and owning an in-house video player, improving live video latency, and developing WebRTC-based real-time systems for interactive education. Key contributions: • Designed and built a custom video.js-based video player used across PW’s web platform • Worked deeply with HLS, ABR strategies, latency tuning, and media playback optimizations • Built and scaled WebRTC-based real-time features including live classes and collaboration tools • Led performance improvements across core LMS flows, improving engagement and reliability • Collaborated closely with product, design, and backend teams on platform-level decisions I enjoy solving complex frontend and platform problems — especially where scale, real-time systems, performance, and user experience intersect.
