Top SchoolShekhar Rajak is a Senior Software Engineer with 11 years of experience building scalable data platforms and full-stack systems across companies like Apple, Salesforce, and Atlassian.

An active open-source contributor and long-time GSoC mentor, he authored the Ruby daru-view gem and has contributed to high-profile projects such as SymPy, NumPy/SciPy, Kubeflow and Bundler. Comfortable at the intersection of distributed systems, ML platforms and developer tooling, he has a track record of turning research-grade tools into production-ready components and mentoring the next generation of contributors. A detail that sets him apart: he blends low-level performance work (CUDA, Numba) with developer ergonomics—writing documentation, tests and interactive visualization tooling—to make complex systems usable.
