Rockstar🎓
Top SchoolYueh-hsuan Chiang is a Head of Engineering based in Menlo Park with a PhD in Computer Science and over a decade of systems experience culminating in leadership roles across startups and blockchain. Previously a Core Software Engineer at Solana Labs and a top-four all-time contributor to RocksDB at Facebook, he specializes in high-performance storage, ledger persistence, and database C APIs. His open-source work includes significant enhancements to RocksDB’s C API and Solana’s blockstore and ledger modules, improving multi-get, metadata handling, and efficient append-vector storage. Known for bridging deep systems engineering with product needs, he has a track record of shipping data recovery tools and platform canaries that support large-scale services. An underappreciated thread in his career is consistent focus on metadata and migration paths—making complex data migrations and storage transitions reliable in production.

A library that provides an embeddable, persistent key-value store for fast storage.
Role in this project:Back-end Developer / Database Engineer
Back-end Developer / Database EngineerContributions:8 reviews, 6 commits, 9 PRs in 8 months
Contributions summary:Yueh-hsuan contributed significantly to the C API of RocksDB, a persistent key-value store. Their work involved implementing new functions, notably for batched multi-get operations, and adding metadata-related features to the API, including functions to retrieve and destroy metadata objects. They also enhanced the API with functions for compacting ranges and loading options. Furthermore, the user added a feature to enable multi-level databases to smoothly migrate to FIFO via DB::Open and included a change to ensure the column family paths are specified in the options.
