Summary
👤
Senior🎓
Top SchoolHarshad Shirwadkar is a seasoned software engineer with 15 years’ experience specializing in storage, operating systems, networking, and distributed systems, currently building low-level file system and block-layer software on Google’s storage team. He combines production-grade engineering at scale with academic depth from an M.S. in Information Networking at Carnegie Mellon, where he researched network and transport-layer systems. His open-source contributions to the widely used e2fsprogs project show practical expertise in ext2/3/4 internals—adding bigalloc support, refactoring core libraries, and improving tools like e2fsck and debugfs. Earlier roles span Wi‑Fi driver and security tooling development at AirTight Networks and kernel-adjacent projects from Google Summer of Code, reflecting a knack for bridging driver, kernel, and userland code. Based in Bothell, WA, he brings a pragmatic, systems-first mindset that surfaces in both production infrastructure and low-level troubleshooting.

Contributions summary:Harshad primarily contributed to the e2fsprogs repository by implementing and modifying file system utilities, specifically focusing on the ext2/3/4 file systems. Their work involved changes related to the handling of clusters, blocks, and inodes, especially in relation to the bigalloc feature. The user's contributions are evident in the modifications made to the e2fsck and debugfs tools, as well as the addition of kernel endianness conversion macros. The user also refactored the codebase by moving the `calculate_summary_stats` function to the libext2fs library and providing APIs to configure fast commit blocks.
