Developer experience as product. Twenty years building platforms that other people build on — API ecosystems, developer tooling, and now the infrastructure underneath AI agents. Currently independent, shipping under @orchestrately.

Four issues filed, all four closed as fixed. Fix for the last one merged as #3701.

• A drain worker self-deadlocking at concurrency=1, stalling any cycle phase that spawned a subagent
• Owner identity fragmenting across three different holder strings
• A calibration default that silently no-op'd forecasting on every non-owner brain
• A cycle phase hardcoded to source=default, never scoped to the resolved id

• Fixed a merge-tracker regex that never matched the documented inline **URL:** header, leaving URL dedup silently inactive. Merged as #2926.
• #824, open — create-a-role "gambit" mode and Speculative pipeline state.

A Claude Code plugin that scouts a Rails monolith and reports how entangled a domain is and which seams must break before it can be extracted. Cites every claim and says what it didn't look at. No dependencies beyond Ruby's stdlib.

Realtime dashboard and activity log for local LLM inference on Apple Silicon. A small TypeScript server polls MTPLX's /metrics and streams to the browser over SSE; the frontend is four plain HTML files — no client framework, no build step. Surfaces the part of speculative decoding that actually matters: tokens per verify pass, per-depth acceptance, throughput, cache health.

StructuredREMI and MuMIDI tokenizers extended to carry MIDI control-change data. The public edge of Ravel AI — an AI-first DAW that generates expressive MIDI: the dynamics, articulation, and phrasing that make a part sound played rather than entered.

Retrieval over an organizational decision log, so "can we accept NET120 terms?" gets answered from the record instead of from memory.

• Famlore — A game of inquiry that runs through the AI client you already use: it keeps the record of what you're furthest into and hands you one specific thing to go find out. Next.js and Supabase, an MCP server, and a Claude plugin.
• Colophon (pre-release) — A macOS catalog for every sample library you own. Reads Kontakt, SINE and Audio Unit installs into one searchable index, queryable from the app or from your AI assistant over MCP.
• Sylvaness (building) — A playable study of a living forest: trees grown by space colonization with seasonal leaves, no imported models. One deterministic simulation drives a Three.js build and a native SwiftUI/Metal prototype.
• Stockstead — Mortgage modeling for the cases standard calculators refuse: SBLOCs, tax-loss harvesting, portfolio-backed lending.
• Timeblind — Visual time-blocking for when ADHD makes the clock invisible. Gentle nudges, not guilt-trips.
• Forbearance — A word game that teaches you to do without.
• Historic — Walk up to a landmark, get an AI-narrated podcast on the spot. Fine-tuned Gemma 3 on-device, Swift and AR on top.

• Klout (2011–2016) — Built the developer platform from zero to 7-figure ARR and 60% of company revenue; API latency from hundreds of milliseconds to ~12ms. Exit to Lithium, where I ran Klout and consumer data as VP/GM.
• Tagboard (2016–2024) — CPO through the turnaround. ARR $600K → $7.2M, churn 65% → 8%, seven products onto one platform.
• Canvs AI (2018–2019) — Rebuilt emotion and topic models from ~70% to ~85% precision/recall.
• AWS (2024–2026) — AI/ML startups. GenAI and small-model playbooks for LoRA fine-tuning and evaluation, used by founders and field teams.
