Multigrid

TypeScript and Next.js App Router, Python, SQLite/Drizzle, Stripe, Caddy and systemd on one small Linux box. Generalist who ends up in the billing code and the memory profiler more than expected.

Inference economics — deriving the arithmetic instead of repeating it. KV-cache growth, the memory-bandwidth roofline, and why 4-bit weights cost 0.578 bytes each rather than 0.5.

Multigrid: a model gateway with real cost and latency telemetry. Alongside it, a technical library on inference — released on a schedule rather than dumped all at once.

Happy to talk about gateway architecture, provider failover, per-request cost accounting, or running inference on a budget. Also genuinely want to hear it when something I've written is wrong.
