Rockstar🎓
Top SchoolSushant Bhat is a detail-oriented data and performance engineer based in Pune with over eight years of professional experience and three years focused in software-related roles. He combines data analysis and backend performance optimization, having worked at NVIDIA in process and senior process roles and currently at Tata Consultancy Services as an IT Analyst. His open-source contributions to the high-profile LLVM project highlight practical expertise in compiler performance—fixing InstCombine bugs, improving cost models for AArch64, and adding tests that boosted vectorization and floating-point operation handling. This blend of hands-on systems-level performance work and data analytics enables him to diagnose subtle runtime issues and translate them into measurable improvements. Colleagues describe him as methodical and persistent, comfortable navigating both low-level compiler internals and higher-level operational metrics. He holds a BE from D. Y. Patil College of Engineering and brings a pragmatic, results-driven approach to complex engineering challenges.
