Over Vadim

I build distributed systems that survive scale and adversaries: 10,000+ reads/sec reputation engines in Rust, event-driven architectures (CQRS, NATS JetStream) for edge datacenter fleets, P2P protocols shipped to production. 15+ years across backend engineering, HPC/GPU computing and P2P networks. I take over large legacy codebases and cut them down to fast, tested systems — at TU Delft I reduced 100k+ lines of Python by 80% while improving key metrics 4–100x. Currently open to senior backend / distributed systems roles (Python, Rust) — employment or interim via my own B.V. Based in Delft, hybrid across Randstad or remote. Available immediately.
