Aaron Feldman is a software engineer based in San Francisco with 11 years of experience building high-performance back-end systems, currently at Meta. A Caltech CS and Mathematics graduate, he has deep expertise in storage and databases evidenced by substantive contributions to RocksDB — adding cache management functions, fixing memory leaks, and enabling multithreaded backup/restore. He translates low-level systems work into reliable production features, and has iterated on benchmarking tools to give teams finer control over caching behavior. Past internships at Google and research at JPL reflect a strong foundation in rigorous engineering and large-scale systems. Notably, his profile photo at Point Reyes hints at a preference for precision over methodology dogma — practical engineering, not waterfall endorsements.
