Systems engineer — Rust, Go, C. I work on low-level, performance-critical networking: eBPF/XDP and AF_XDP data planes, DPDK packet processing tuned to hardware line rate, and 5G core components (UPF, custom 4G/5G gateways doing SCTP/GTP-U NAT with S1AP/NGAP signaling inspection) at a telecom operator.
On the side I build trading infrastructure in Rust: an exchange-connected algorithmic trading system with backtesting, live execution, and a market-making module, sponsored by a trading firm.
Most of my substantial work — the 5G data planes, the trading system, and a from-scratch TCP stack — lives in private or employer repositories. I'm happy to walk through any of it in an interview.
