A social audio analysis platform for producers and sound engineers. Upload any sound, get an instant breakdown: BPM, key detection, waveform classification, ADSR envelope, tone and texture. All computed client-side with custom FFT and DSP in Web Workers. Downloadable Vital synth presets, Ableton recipes, AI stem separation, plus a full social layer.
I see problems.
I build solutions.
I'm Spencer Curnow, a psychology grad turned self-taught developer. I take a vision and ship it, using AI-augmented development to compress weeks of work into days. Most recently Sleeve, a social app for music fans now live on the App Store, plus ongoing design work for Yurr Magazine. If you have something you want built, I'd like to build it for you.



Sleeve
Where music finds friends.
A social app for people who love albums. Log what you listen to, rate it ½ to 5 stars, write reviews, and find the people whose taste actually tracks yours. No algorithm deciding what you hear. The signature touch: every album page is wrapped in its own color pulled straight from the cover art, so a review reads like a little mood piece instead of a row in a database. Built solo, end to end: Apple Music import, on-device color extraction, taste-twin matching, lists, and a vinyl discovery feed.

Yurr Magazine
Client work: a zine for cool people doing cool things.
Yurr is an independent magazine that profiles one creator per issue, published as Instagram carousels. I art-direct and design every drop end to end: cover, seven question-and-answer spreads, outfit callouts, and the closing grid. To keep eight issues consistent and fast to ship, I built the rendering toolkit behind them in Python and Pillow: a typographic system, shadow and glow compositing, a reactive callout library, and a one-command build per issue.

Dogleg
A golf scorecard that feels like the clubhouse, not a spreadsheet.
Tap to score every hole, with live GPS distance to the green (wind and elevation adjusted) and a real USGA handicap that recalculates the moment you sign the card. Satellite hole maps, shareable round posters for the group chat, and a feed where your crew's rounds land. Built solo, end to end, on React Native and Supabase, with color, distance, and scoring computed on-device. Held to a 60+ accessibility floor, because the first user was my dad's Saturday foursome.

More from the catalog.
Before Dogleg there was a steady stream of side projects. Every one started with a real problem and shipped end-to-end. No tutorials, no toy apps, no abandoned half-builds.
Scans 6 platforms (Reddit, Hacker News, Dev.to, Remotive, Jobicy, RemoteOK) every two hours. Surfaces freelance opportunities and scores them via a trainable keyword-weight model. Pro tier adds instant email alerts, budget parsing, and CSV export.
Automated daily job-search agent. Pulls listings from JSearch and Remotive, runs a two-pass scoring system (keyword filter, then Gemini fit analysis with resume matching and cover-letter talking points), and delivers a curated HTML digest to my inbox every morning.
A private, auth-gated cross-project dashboard I built into this site. One pane of glass for every product I run: PostHog HogQL queries for events, retention, and feature-flag state, plus Sentry issue counts, all proxied server-side so no credentials touch the browser. Unified activity feed across Dogleg, Job Scout, and this site.
Not your typical developer.
I studied psychology at Boise State, earned a Music Production certificate, ran intramural sports for 1,900+ student participants, and currently lead PT aide operations at Prevail Physical Therapy in Shoreline.
I've always had ideas for tools I wished existed but didn't know how to code. When AI-assisted development clicked, everything else followed. Now I ship full-stack products in weeks, not months, combining a working knowledge of how people behave with the ability to actually build things.
Every project I've shipped started with a real problem I wanted to solve. Not a tutorial. Not a portfolio piece. A thing I needed, that I went and made.

How I work differently.
Three things that compound. Each one shapes how I pick what to build, how fast I build it, and whether it actually ships.
- 01
Psychology, before pixels.
A BS in Psychology means I identify why users struggle before I touch a line of code. Real empathy, not assumed personas.
- 02
AI as a thinking partner.
Claude Code accelerates the work without cutting corners. I move faster on the boring parts so I can spend more time on the interesting ones.
- 03
Ship, or it didn't happen.
Not prototypes. Not demos. Live products with Stripe payments, auth flows, actual users. If it isn't in production, it isn't done.
How I got here.
Two tracks running in parallel since 2024: shipping products on nights and weekends, and running customer-facing operations during the day. Both inform each other.

Drove 92% year-over-year retention across a 1,900+ participant base. Led a 29-person staff, administered the IMLeagues SaaS platform across 1,000+ annual events, lifted CSAT 15% via Qualtrics-driven interventions.
The toolkit.
Picked one tool at a time, each chosen for a real project, not a tutorial. Heavy on the React + Supabase + Cloudflare side; comfortable anywhere the stack is plain JavaScript and a good API.

Let's build something together.
Project work is the headline. Send me what you want built, we'll scope it and figure out payment in conversation. Full-time roles welcome too if the fit is right.
