case studies
Writing
Neutral studies of systems I've built and run — what each is, and what shipped.
Spaces — a desktop platform that freezes and thaws whole workspaces
Organizes a machine into Spaces — each with its own apps, layout, and local-model context — that freeze and thaw on a keystroke. GNOME + Hyprland from a shared core.
mapit → shipit — a five-stage delivery pipeline
A five-stage promotion pipeline (T0 → T1 → T2) implemented as tooling, plus the continuity and decision artifacts that make engagements repeatable.
System cartography — schema-first maps and typed graphs
A wide-net cartography method that catalogs an unfamiliar domain before any build, and two typed graphs that make a corpus queryable.
Enforcement RCA — a root-cause program for a live ML model
A repeatable root-cause-analysis program for a live ML enforcement system. Methodology only — no platform-internal data.
Governance patterns — instruments that keep a rule enforced
An adversarial multi-judge review panel and an access control paired with a reconciliation loop — two shapes for turning a declared rule into an enforced one.
gfx1150-bench — inference tuning on a handheld iGPU
A controlled performance study on an AMD handheld iGPU: roofline, an 8-model ROCm-vs-Vulkan matrix, and a 2.43× speculative-decoding result.
Industrial edge — a sprayer diagnostic, a field curriculum, a protocol library
A CAN/GPS diagnostic on agricultural spray equipment, a field curriculum, and the public protocol library that backs the domain.
SecondChair — self-hosted legal RAG
A self-hosted, privilege-aware legal retrieval-and-analysis system built with a small practice; v1 shipped to production in a seven-day engagement.
Reproducible, keyless agent evals
A record/replay seam that lets an agent-eval harness reproduce its scorecard in CI with no API key — plus the deterministic hard-gate mechanism that rides on top of it.
inkSpec — one engine, any design system
A no-build, offline, single-file HTML engine that renders LLM-authorable specs as forms and dashboards — and ingests any third-party design system as one CSS file of tokens against a thin, enforced contract.
