I build iOS apps that make money. If yours doesn't, we should talk. Most iOS developers ship features. I ship revenue. In the last 8 years, apps I've built have generated $500K+ for my clients, not because I write "clean code" (everyone claims that), but because I obsess over the 3 things 90% of developers ignore: conversion, retention, and App Store ranking. What I actually do: Build native iOS apps in Swift/SwiftUI that get featured, ranked, and downloaded. Then I make sure they don't leak users through a bad onboarding, broken paywall, or App Store listing nobody clicks. A few receipts: - Telehealth app → 10K patients, $500K seed round (HIPAA-compliant, Core Data, CloudKit sync) - DTC e-commerce app → 312% mobile revenue lift (Apple Pay, custom checkout that doesn't suck) - EdTech app → 4.9★, featured in "Apps We Love" (SwiftUI, built in 7 weeks) - Social app → 50K DAU, 1M+ messages/day (Firebase, real-time, zero downtime in 18 months) How I work: I don't take every project. I take 2 per quarter. If we're a fit, you get: - A working TestFlight build in week 2, not week 8 - Direct access to me, not an account manager - An opinionated partner who'll push back when your idea is wrong (and tell you why) - A 99.8% crash-free app, or I fix it on my dime I'm probably not for you if: - You want the cheapest developer on Upwork (I'm not) - You need someone to just "code what I tell them" (I'll ask why first) - You don't have a clear sense of who your user is (I'll help, but you have to care) I'm exactly right for you if: You've got a real product, a real budget, and you want it built by someone who's shipped apps that people actually use and pay for, not someone padding a portfolio.
