Pranjal Kumar is a Software Engineer III at Google with a decade of experience building performant backend systems and research-driven features, rooted in a BTech and Masters-by-Research in Computer Vision from IIIT Hyderabad. At Google he progressed from SDE II to his current role, applying production-grade engineering to large-scale services while drawing on earlier backend work in payment flows at Directi. His academic and research background includes contributions to computer vision labs and teaching, giving him a strong foundation in algorithms and systems thinking. An active open-source contributor, he improved the widely used nanoflann C++ kd-tree library—adding dynamic insertion/deletion and fixing core KD-tree bugs—demonstrating low-level performance tuning skills that complement his cloud-scale experience. Based in Sunnyvale, he blends research rigor with practical delivery, comfortable moving between algorithmic detail and production trade-offs. Colleagues would describe him as a pragmatic problem-solver who surfaces subtle implementation issues before they reach production.
