01 Uses A practical colophon

What I work with.

The actual tools, stack, and workflow behind the work on this site. Updated when something changes, not on a schedule.

02

Editor & code

05
VS Code
Daily driver. JetBrains keymap, no theme overrides.
Cursor
When the work is local iteration on a tight loop.
Claude Code
When the work needs to think across more than one file.
iTerm2 + zsh
Tabbed sessions, per-project profiles.
GitHub Desktop
For diffs and quick commits. Branching and rebasing in CLI.
03

Design

03
Figma
Precision design, component-system maintenance, handoff fidelity.
Claude Design
Visual exploration when a frame is faster to think in than markup.
iA Writer
Writing-first for long-form content and case study drafts.
04

Stack

07
TypeScript
Default for everything I author from scratch.
Astro
This site. Static-first, content collections, MDX, view transitions.
React + React Native (Expo)
ChatOBD2 mobile + web surfaces.
ASP.NET MVC + Razor
MagTek platform. Razor partial library past 100 typed components.
Hand-written CSS
Tokens, layout primitives. No utility-class framework on this site.
Tailwind
On projects where the team is already on it.
Supabase
Database, auth, edge functions for ChatOBD2.
05

AI workflow

04
Prompt modules in source
Typed, versioned, reviewed in PRs like any other code.
Schema-bound outputs
Model output is constrained at the boundary, not at the UI layer.
Deterministic layers in front
Six reasoning layers run before every model call in ChatOBD2.
Token budgets as resource budgets
38,000-token system prompt assembled per scan, P0 sections always make the cut.
06

Hardware

03
MacBook Pro 14"
M3 Pro, 36 GB. Daily.
Studio Display
Single screen, no second monitor. Forces tab discipline.
iPhone 15 Pro
Always nearby, mostly because of ChatOBD2 testing.
