I'm an engineer. I've been writing production software for over twenty years - open source, with startups and in enterprise environments.
Last few years have been agents, MCP, and the infrastructure that makes them actually shippable. I run squirrelscan.com a deterministic agent based website auditing tool for performance, security and SEO issues with over 50k installs. I ship agent tooling like drover and taskmux because the existing tools weren't the shape I wanted them to be.
When teams need to own the stack or keep data in-house, I post-train open-source models — Qwen, Kimi — and self-host them on their infra, sized to hit cost and latency targets the frontier APIs can't.
Nineprimes is deliberately small. I take on a few client engagements at a time, focused right now on agent rollouts for GTM teams at funded startups and enterprises. Direct work, no account managers, no offshore handoff.
