About
I build high-performance distributed systems in Go, Python and Rust. Most of my recent work is mobile security: reverse engineering Android and iOS applications, instrumenting them at runtime, and building the protections that have to survive the same treatment. Underneath that sits system-level work — eBPF, TUN stacks, low-level networking — and native Swift on Apple platforms.
I build high-performance distributed systems, low-level security tools, and autonomous AI agents that understand real codebases. My expertise spans building scalable Go/Python backends, eBPF networking, iOS/Android reverse engineering, and full-stack development.
Currently building Lexa and ctx-agent.

Most of what I build sits in private repositories, so there is nothing here to click. That does not make it less real — it is the bulk of the work, and it is where the interesting parts live. What this site describes is capability, not the engagement.
