A studio for software that ships.

Three products. All shipped solo.
Each product was conceived, designed, engineered, and launched by a team of one. They run today — paying users, App Store reviews, real revenue. Drag the device or pick a face below.

In development
A new iOS product. Targeting Q4 2026 launch.
02 — Manifesto
What we believe, five at a time.
.01
Sole authorship over committee design.
A clear point of view ships faster and ages better than consensus. One person made every decision in every product we've launched.
.02
Production over polish theater.
A live product with paying users is worth more than a portfolio piece, every time. We measure quality by what's deployed, not what's framed.
.03
Native craft over cross-platform shortcuts.
SwiftUI for iOS. Real React for web. Server-rendered when it should be. The shortcut you take in week one is a tax you pay in year three.
.04
AI as a tool, not the product.
We use LLMs in our pipeline daily. We rarely sell them as the headline. The interesting product is the one where the AI is invisible.
.05
Few clients. Long engagements.
Two to three projects per year, six-week minimum. The depth a small studio can offer is a function of how rarely we're forced to context-switch.
.06
Honest over impressive.
If a thing is hard, we say it's hard. If a deadline is at risk, you'll know before the deadline. Surprises are the opposite of professionalism.

04 — Services
Three things we do well enough to charge for.
/01 — Native iOS
Polished iOS apps.
SwiftUI, App Store launch, in-app purchases, analytics, support flows. Indie-grade craft in a six- to ten-week build cycle.
- From concept to App Store
- SwiftUI · UIKit · Core Data
- StoreKit 2 + RevenueCat
- TestFlight cohorts
/02 — Web
Web apps and websites.
React + Next.js, server-rendered, accessible, deployed on Vercel or Cloudflare. Marketing sites that load in under a second.
- Next.js · TypeScript · Tailwind
- Postgres + Drizzle / Prisma
- Auth, billing, admin
- Edge-deployed by default
/03 — AI
AI prototypes & consulting.
RAG pipelines, prompt optimization, agent harnesses, custom fine-tunes. Working demo in two weeks; production-hardened in six.
- Claude · GPT · open models
- Vector + hybrid retrieval
- Eval harnesses + observability
- Fractional CTO available
05 — Process
Five weeks. Four steps. One operator.
01
Listen & sketch.
Week 1 · DiscoveryA three-day discovery: the problem, the user, the constraints. Outputs are a one-page brief, a paper sketch of the flow, and an honest go/no-go.
02
Prototype in code.
Week 2 · PrototypeNo Figma marathons. A working prototype on real devices by end of week two. Wrong faster, learn cheaper, iterate sharper.
03
Build to ship.
Weeks 3–5 · BuildThree weeks of focused build. Daily deployable trunk. Friday demo to you. Production-grade tests, observability, and rollback paths from day one.
04
Hand over & stay close.
Week 6+ · AftercareDocumentation written for the next engineer, not for archive. Two weeks of post-launch support included. Retainer for ongoing work, optional.
