iOS app development
iOS work that ships and holds up.
New apps, stalled apps, and the technical problems that quietly stop growth. Built for founders who need a grown-up engineer, not a pitch.
I have spent more than 15 years on Apple platforms and helped ship close to 100 apps. iOS is a craft: architecture, performance, App Store rules, and the details users feel immediately.
If you are starting from zero, we scope tightly and build what you actually need first. If you already have an app, I look for the real drag: crashes, review-killing bugs, clumsy onboarding, ignored feedback, analytics you cannot trust. Then I fix that.
A good fit if
- You need an iOS app built, rebuilt, or unblocked.
- You want technical advice before you spend the budget.
- Growth is stalling and you suspect the product, not ‘the algorithm’.
