Independent iOS developer
shipping native apps people
actually use.

I'm Harrison. I build and launch iOS apps end-to-end — from design and Swift to backend and App Store. Some make money. Some are side quests. All of them ship.

Apps I've built & shipped

CarEnthu icon

CarEnthu

Collect the cars you sight in the wild

Car spotting meets trading card collecting. Snap a photo of a rare car on the street, add it to your collection, complete the Carbex (like a Pokédex for 500 car models), and earn badges across 5 rarity tiers.

SoberMate icon

SoberMate

Sobriety tracker & recovery companion

A private, secular sobriety tracker built for people who want to stay accountable without the religious overtones of traditional recovery apps. Streak tracking, milestones, mood journaling, and trigger pattern analysis.

StackD icon

StackD

Track. Save. Stack. Your future starts here.

A personal finance app built to make tracking income, expenses, and savings feel less like a chore. Featured an AI-powered payslip analysis tool that broke down tax, super, and take-home pay automatically. An earlier project — shelved but the ideas lived on in later apps.

Solo developer, full stack

I'm a solo iOS developer operating as AppSyntax. I design, build, ship, and maintain every line of code in my apps — from SwiftUI views to Postgres schemas to marketing sites like this one.

My work sits at the intersection of native craft and fast iteration. I prefer SwiftUI over cross-platform frameworks, Supabase over rolling my own backend, and shipping over perfecting. Every app in my portfolio was built, launched, and iterated on in public — not sitting in a folder waiting for a "right time."

I use AI agents heavily to move faster, but I'm the one making the decisions, writing the specs, debugging the edge cases, and taking the App Store rejection notices personally.

// specialties
  • Native iOS (SwiftUI, UIKit, Vision, MapKit, StoreKit)
  • Backend architecture (Supabase, Postgres, edge functions)
  • Real-time multiplayer & social features
  • App Store optimization & launches
  • Subscription monetization & IAP
  • Admin panels (Next.js, Tailwind)

Let's build something

Got an idea, a job, a collaboration, or just want to chat about shipping apps? I'm always interested in hearing from other builders, founders, and people who ship.
