For the past few years I've been building and operating distributed systems, mostly in Rust: real-time event ingestion, custom query engines and memory-efficient data structures. As a founder and sole engineer, I built and still run a product whose infrastructure handles around 40 million requests per week.
My query-engine work includes Roaring-bitmap indexes and lock-free index swaps, so queries don't wait for index refreshes. I've built event-driven systems with deterministic replay, idempotent outputs and crash-safe checkpoints.
I've also designed and implemented content-addressed storage protocols, including verified streaming and end-to-end-encrypted, versioned filesystems over multiple storage backends. I've used Rust/WebAssembly, WebTransport and service workers for verified, encrypted browser streaming, and FFI to integrate native libraries and expose Rust functionality to other runtimes.
I'm looking for a full-time Rust-first role in distributed systems, storage, networking or systems-heavy AI infrastructure, and I'm available to start immediately.
