Available to hire
I’m a systems and blockchain engineer with a strong focus on low-level optimization, Rust-based stacks, and distributed networks. I work on hardware-aware performance, profiling, and building robust infrastructure for trading platforms and blockchain nodes.
I love open source, tinkering, and sharing knowledge. When I have time, I contribute to OSS projects, mentor teammates, and explore topics like IPC, TEEs, ZK proofs, and network protocols.
