The tools behind 100 apps.

Every app in this portfolio is built and run by one person. These are the tools that make that possible, the ones actually in use today. No affiliate links. Where a tool is mine, it says so.

Building the apps

Expo / React Native: Most of the apps are written once in React Native with Expo and built for iPhone.
Claude Code: Planning, writing and reviewing code across every app and site.
Codex: A second coding agent for focused tasks and builds.

Money and measurement

RevenueCat: Subscriptions, entitlements and revenue reporting.
Superwall: Paywalls that can change and be A/B tested without an app update.
AppsFlyer: Install attribution for paid campaigns.
PostHog: Product analytics: which screens people reach and where they stop.

Shipping and the store listing

Agent C (mine): App Store screenshot sets. Disclosure: I build Agent C. It started as the tool I made for these apps' own listings. See the before-and-after sets for apps in this portfolio.
App Store Connect API: Scripted submissions, pricing and metadata instead of clicking through the web UI.
Vercel: Hosts this site and the apps' web pages.
