Independent Apple-platform studio

Native Apple apps that ship properly.

I help founders and product teams build, fix, and extend iOS, iPadOS, and macOS apps. One senior engineer, clear decisions, and native-first judgment where Apple-platform quality matters.

You work directly with Hugo — from the first technical question to the release in people’s hands.

Studio products

I build products too.

That means I know what it takes after the code is written: App Store review, real users, messy data, pricing, support, and the details that decide whether an app is worth keeping.

Studio engagements

Where I can help.

Direct help for founders and product teams that need an Apple app built, rescued, modernized, or moved forward by a senior engineer inside the team.

Start with a focused sprint, a product build, or ongoing senior support. If the problem is unclear, a short audit can be the first step rather than a separate consulting layer.

Native where it matters. Swift, SwiftUI, UIKit, Apple frameworks, and AI features that belong in the product — with pragmatic integration choices when they serve delivery better.

Discuss your project

Understand

Solve the real problem

Start with the user, the constraint, and the smallest useful outcome. Extra screens and clever abstractions do not count as progress.

Make

Make it feel at home

The app should belong on Apple platforms: familiar behavior, good performance, accessible UI, and details that hold up outside the happy path.

Release

Ship, learn, adjust

A working slice teaches more than a long planning document. Release useful increments, watch what happens, and improve the part that matters next.

Start a conversation

Tell me what is stuck.

Share the product, the problem, and the deadline. I’ll reply with a clear view on fit and the next sensible step.

No sales team, handoff, or discovery theatre. Send enough context to understand the situation and I’ll tell you what I would look at first.
