Rockstar🎓
Top SchoolMatthew Saltz is a senior distributed-systems engineer and founder with 12 years of experience building high-performance storage and database infrastructure. He’s contributed to MongoDB’s core server—working on sharding, range deletion, index management and catalog snapshots—and led internal efforts like task cancellation APIs and running the server behind L4 load balancers. As Founder & CTO of EllieDB he designed novel LSM- and log-based embedded key-value stores with fully asynchronous APIs and no internal threads, plus a benchmarking tool that accounts for coordinated omission. He balances hands‑on implementation (race fixes, migration UUIDs, PrimaryOnlyService hardening) with people leadership, having managed small engineering teams at MongoDB. Based in New York, he brings a research-rooted mindset from large-graph and pattern-matching work to pragmatic, low-latency system design. Expect a developer who moves between deep systems plumbing and product-minded engineering with an eye for predictable, high-throughput behavior.
