Summary

Rockstar🎓
Top SchoolPrakash Surya is a Senior Member of Technical Staff with 15 years’ experience building and hardening file systems and low-level storage software, currently contributing to ZFS development at Delphix. He has deep systems and kernel expertise demonstrated by substantial open-source contributions to illumos and OpenZFS—adding features like a REFRATIO property, improving arcstats visibility, and fixing metaslab, locking, and memory issues. Prior work at Lawrence Livermore National Laboratory on the Lustre file system and earlier full-stack internships show a practical blend of systems engineering and application development. Based in North Las Vegas, he pairs an academic background in computer science and applied mathematics with a track record of shipping robust, performance-critical code. An often-overlooked strength is his sustained focus on observability and correctness in storage internals, which helps surface subtle runtime issues before they impact production.

Contributions summary:Prakash primarily contributed to the `illumos/illumos-gate` repository, an open-source Unix operating system. Their work focused on enhancing the ZFS (Zettabyte File System) functionality. This involved implementing new features like the `refratio` property, addressing a panic related to metaslab initialization, adding more visibility via `arcstats`, and fixing multiple issues related to locking, memory allocation, and performance within ZFS.

Jul 2011 - Feb 2021
OpenZFS on Linux and FreeBSD
Role in this project:Back-end Developer & Systems Engineer
Back-end Developer & Systems EngineerContributions:55 reviews, 94 commits, 24 PRs in 9 years 8 months
Contributions summary:Prakash's contributions primarily focus on enhancing the ZFS codebase, with a clear emphasis on low-level system interactions and kernel-level modifications. The user added a "REFRATIO" property to retrieve compression ratios, and implemented several bug fixes. Furthermore, the user converted 'if' statements to 'AS_IF' in kernel.m4, and added code coverage enhancements.
