Portfolio · Updated May 2026
Twenty years in music production. In February I started using Claude as a coding partner, mostly to build the tools I'd been wishing existed (the studio I wanted, the eBay/Reverb shop I wanted, the home dashboard I wanted).
Below: what shipped, what runs in the background, and how it all landed in three months.
Shipping Products
Products with a public URL, a buyer, or a store presence. The Schwung modules sit underneath the framework card, since they all depend on it.
Universal MIDI controller that turns Ableton Move into a standalone hardware controller for rack synths and grooveboxes. Sixteen encoders, ready-made templates for OP-XY, Proteus 2000, Blofeld, Korg M1, Nord Drum 3P, SP-404 MKII, SeqTrak, and more.
Open framework for running custom instruments, effects, and MIDI tools on Ableton Move through RNBO Takeover. Underpins every module below.
Category-aware patch randomizer for the Dave Smith Tempest. Generates kicks, snares, hats, toms, claps, perc, and bass with four variants per category. Hardware-validated against the real machine.
Thirty hand-drawn drum machines. Adult coloring book, paperback. The reference photos took weeks to source and verify against my own collection.
Burned and tested HR-16 sound EPROMs (the early Akai/Linn drum machine ROMs) plus original OP-1 buttons and knobs. Sold on Reverb and eBay, shipped same week.
The hub. Cloudflare Pages with a Brevo email funnel, product landing pages, and a manual library gated behind purchase. Edited live in Claude Code and deployed via Wrangler.
Automation Fabric
The wiring matters as much as the apps. Most of what's below runs without me touching it. I check Slack in the morning and pieces have already moved.
| Trigger | What Claude does | Output |
|---|---|---|
| launchd, every day at 9pm | Scans my Claude Code session JSONLs and summarizes the day's work | Slack #work-log digest |
| launchd, Sundays at 9:30pm | Pulls YouTube, Gumroad, Patreon, and Brevo metrics for the week | Slack analytics digest |
| Daemon, every 60 seconds | Polls eBay Browse API and Reverb for gear that matches my saved searches | Slack #deal-monitor alert |
| "ship it" in Claude Code | Fetches unshipped orders from eBay and Reverb, applies package presets, picks the cheapest USPS rate | Shippo label PDF, ready to print |
| Buyer message on Reverb or eBay | Drafts the reply in my voice (the voice files keep it honest), posts it via the platform's MCP server | Reply on the listing |
| "Remind me at X" in chat | Writes a launchd plist that fires a Brevo transactional email | Email arrives in my inbox on schedule |
| Edit to the site repo | wrangler pages deploy on the working tree | justinjoe.com live in under a minute |
| Coding session | Serena MCP for symbol-level edits, Playwright MCP for browser testing | Code committed and verified before I look at it |
Daily-Use Tools
Personal tooling. None of these are products, but the count is the point. If I'm doing something twice, I build a thing.
eBay and Reverb gear-deal alerts to Slack. Polls every minute, deduplicates, won't shut up about a clean OP-1 under list.
Scans Claude Code session JSONLs each night, condenses what I actually got done, posts to Slack so I can scroll back through a week without re-reading transcripts.
Weekly digest pulling YouTube, Gumroad, Patreon, and Brevo into one Slack message. Five-minute Sunday read instead of five tabs.
Local YNAB replacement. FastAPI plus SQLite, paste-from-spreadsheet import, single Waterfront account. Lives on Tailscale, no auth needed.
Single-screen weather web app for the kitchen iPad mini (the old A1599, stuck on iOS 12). Open-Meteo plus NWS, plain ES5.
"Remind me at X" in any Claude chat becomes a launchd plist that fires a Brevo email. The reminder shows up in my inbox at the right time. No third-party reminder app.
One command in Claude Code fetches unshipped orders from eBay and Reverb, applies my package presets, finds the cheapest USPS rate, hands me the label PDF.
Tiny GitHub repo that doubles as an image CDN for Reverb listings (Reverb's API can add photos but not delete, so hosted URLs save a lot of cleanup).
Audio analyzer that detects the musical key, BPM, and chords from a track. Web app today, native macOS port planned.
Personal flashcard system for Koine Greek. Started with the words occurring 500+ times in the New Testament, expanded down to lower-frequency decks. Erasmian pronunciation. Daily review on the iPad.
Velocity
Every milestone below is a real git commit, not a marketing date. The cadence is the point: one shipped thing per week, more or less, since February.
What I Work With
Most of this is stuff I learned by needing it. Order is roughly how often I touch it in a given week.
Contact
Always happy to talk to people making things. Most of my best collaborations have started with someone sending a short email about a problem they couldn't quite solve. If that's you, the inbox is open.
Open to: paid work on AI workflows or music tooling, sound-design or production projects, sample-pack and preset commissions, and the occasional "can you take a look at this synth I'm porting" conversation.
