Field notes from the work, not think-pieces.

Short, practical write-ups on the things I'm actually building — a backtest that lied to me, an agent pipeline that paid for itself, a filmmaking trick that finally clicked. Written so the next person skips the mistake.

The Backtest That Lied to Me

How a 70% win-rate model fell apart out of sample, and the walk-forward discipline I now run before trusting any equity curve.

Wiring 100+ Agents Without Losing the Plot

RAG-based routing, per-provider rate limits, and the failure modes that show up only when many specialized agents share one pipeline.

Designing Workflows That Fail Gracefully

Retries, idempotency, and logging — the unglamorous parts that decide whether an automation saves time or quietly creates more work.

Holding Continuity Across Generated Shots

Keeping character, light, and mood consistent frame to frame — the prompting and editing process behind a coherent AI-directed cut.
