Yusuf shipped the entire paywall, A/B test setup, and App Store submission in under a week. We went from idea to first paying subscriber faster than I thought possible.

About

A little background.

I started writing code at 12 and never really stopped. The last five years I've spent heads down on mobile, primarily iOS in Swift, with Flutter for the projects that need it. Twenty apps in, I've stopped counting downloads and started caring about who's still paying after month three.

I build subscription apps because the math actually works at small scale. A single app with real retention can quietly outearn a whole client services business, without the meetings. Direct relationship with paying users, organic ASO instead of paid ads, compound growth. It's the only mobile business model that lets a single engineer ship something durable.

Working together is direct and async. We talk on email, you get the build in 2 to 4 weeks, and I stay close for a month after launch to fix what real users break. No standups, no project managers, no middleman.

I take on a small number of projects each year so the ones I do take on get my full attention. If we work together, you're not competing with five other clients for my hours.
