Nikolai S.

rust systems engineer, 9 years professional experience, 6 years production rust. currently working on linux kernel modules and ebpf networking - parallel packet processing across cpu cores, kernel-level race condition debugging, traffic control at kernel level with zero userspace overhead. built production backends in rust (axum, rocket, tokio, sqlx, postgresql) for almost 2 years at nxlog - event-driven architecture, bidirectional data sync with retry logic. got an upstream fix merged into openvpn 2.6.20. also built trading infrastructure - order book with matching engine (lock-free ring buffers, nanosecond timing), automated trading with alpaca/bybit, and a complete solana DEX with AMM from scratch using anchor. I work across the full rust spectrum - from no_std kernel code and C FFI to async web services. comfortable with concurrency at every level: kernel-space RCU/spinlocks/atomics to userspace Arc/Mutex/RwLock/channels. looking for rust systems, backend, networking, trading, or infrastructure work. $50+/hr, remote.
