Notes on building practical AI systems — plus tech opinions and a clearly separated personal stream.
A GenAI project succeeds or fails on whether you can name the business metric it moved — and prove it. The architecture is the price of entry, not the win.

A hands-on guide to Google's Open Knowledge Format on a JS/TS monorepo: bundle layout, a scaffold script, CI wiring, and outcomes after three months.
Dense retrieval hits a proven geometric ceiling on multi-hop questions and fails silently — similarity scores stay confident even when the evidence is missing.
A green eval suite isn't evidence your agent works — it's the absence of evidence. Mutation testing shows you exactly how blind your evals really are.
In regulated, multi-tenant GenAI, governance isn't a constraint on the build — it's what decides whether you can ship. Design it into the first diagram.
A self-healing feedback loop: tail the logs, feed errors to Claude Code, let it fix, build, and restart — unattended. Here's what it actually fixed.
Ground the model in retrieved evidence, constrain its output, verify its claims, and measure everything. A layered defense against LLM hallucination.
RAG quality by vibes doesn't survive a second engineer. Decompose by stage, build the eval set from real failures, calibrate the LLM judge, and gate CI.
A research-backed breakdown of the prompting methods — from zero-shot to ReAct — that reliably produce better, smarter, more useful AI output.
Shipping production AI isn't about model benchmarks; it's the reliability, retries, fallbacks, observability, and cost discipline that keep LLM systems alive.
Five layers — context file, plan gate, atomic tasks, git checkpoints, verification loop — that make AI agents fast and trustworthy instead of chaotic.
What distance running taught me about debugging: both reward patience, a steady pace, and trusting the process long before you can see the finish line.
Episodic, bi-temporal memory with Graphiti lets an AI agent answer not just what's true now, but what was true when, without re-indexing the whole world.
