How I can help
Focused support for founders and teams who need senior iOS execution without losing product judgment.
AI-powered mobile features
Turn AI APIs into native UX with backend proxy/API integration, persistence, usage limits, credits/paywalls, and clear failure states.
Payments, StoreKit & entitlements
Build and debug IAP, subscriptions, legacy access, Stripe checkout, Apple Pay, and restore flows.
Launch readiness & stabilization
Audit risky flows, fix blockers, add monitoring, and get the app ready for real users.
Legacy app rescue & architecture cleanup
Untangle older projects, reduce fragile logic, remove dead flows, and make future changes safer.
Mobile + backend integration
Connect apps to Firebase, PHP, Django, APIs, notifications, analytics, and release infrastructure.
Selected client outcomes
Recent work chosen for the kinds of client problems it proves: launch risk, AI API integration, payments, entitlement logic, mobile/backend delivery, and App Store readiness.
