Summary
👤
Senior🎓
Top SchoolRanjit Tulabandu is a technologist and Senior Member Technical Staff with around a decade of hands-on experience specializing in video and image codecs, machine learning–driven quality improvements, and performance optimizations. Based in Bengaluru, he has led teams at Ittiam Systems to improve open-source video encoders (VP9/AV1) for faster decode and real-time/OTT use cases, driving standardization and roadmap decisions. His work blends low-level C engineering, multi-threading and server/client system design with ML-based algorithm prototypes such as sub-pel filter selection and lookahead/2-pass rate control. Notably, he contributed performance-critical fixes and multithreading to the libvpx VP9 encoder, improving encoder throughput and quality. Ranjit pairs an academic grounding in signal processing from IISc with extensive product-focused codec engineering dating back to H.264/HEVC implementations and platform integrations. He brings a pragmatic mix of research-led experimentation and production-grade optimization that accelerates encoding pipelines while preserving visual quality.
