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 โ 10K patients, $500K seed round (HIPAA-compliant, Core Data, CloudKit sync)
- DTC e-commerce app โ 312% mobile revenue lift (Apple Pay, custom checkout that doesn't suck)
- EdTech app โ 4.9โ , featured in "Apps We Love" (SwiftUI, built in 7 weeks)
- Social app โ 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.
