Top SchoolDibyo Majumdar is a Member of Technical Staff based in Berkeley with 12 years of experience building product-focused engineering teams and shipping cross-platform systems spanning cloud, robotics, web and iOS. He has guided products through startup-to-acquisition stages and led teams at Gradescope/Turnitin where he drove major integrations, doubled usage during critical periods, and authored hundreds of PRs while improving developer DX. More recently he architected a serverless monorepo AWS infrastructure and introduced a shared JSON-schema types system to streamline multi-repo, multi-language development at Beacon AI. Dibyo combines hands-on implementation—full-stack feature delivery and CI/data pipelines—with people leadership, hiring and mentoring engineers and running technical interviews at scale. He contributes to open-source data-science tooling (enhancing table/pivot functionality) and built a high-use student-facing scheduler for UC Berkeley, showing a knack for practical tools that meet real user needs. He’s seeking more strategic product work with a user-centric lens, grounded in a track record of turning ambiguous problems into shipped value.
