Consulting / visionOS / Vision Pro

visionOS & Vision Pro Consulting

visionOS and Vision Pro consulting. SwiftUI for spatial computing, RealityKit for 3D, gaze-and-pinch interaction design, and the pragmatic answer to whether your product should ship on Vision Pro at all.

  • visionOS apps that use the space you're standing in
  • gaze-and-pinch interaction design that users discover on their own
  • accessibility on Vision Pro: VoiceOver rotors, reduced motion, motion-sickness avoidance

"Vadim was instrumental to the success Epsy enjoyed on iOS, taking it from an idea on a Miro board to the highest rated and most downloaded app of its kind on the store."

James C. · Mobile Engineering Lead, Epsy

"We had a strict deadline, and Vadim managed to complete the job in time. He gave us meaningful feedback and suggested better approaches, not trying to blindly stick to our specification."

Founder · Pre-seed streaming service

"I can say with confidence that it will be difficult to find a better developer. Vadim is achievement-oriented, highly organized, with very good communication skills."

Alex Z. · Co-Founder, eda.so

Does our product belong on Vision Pro?

It depends on whether your product uses the space. Good candidates: spatial browsing of dense data (graphs, CAD, architectural review), training or simulation where 1:1 scale matters, ambient reference that benefits from peripheral visibility, entertainment that exploits presence. Poor candidates: traditional 2D productivity, forms, settings, anything the user would open in a queue.

Can you reuse our iOS codebase?

Most SwiftUI views port with minor tweaks. RealityKit-heavy parts are visionOS-specific. I'll map the reuse boundary in the first engagement day so you know what's free and what's bespoke.

Can you build with RealityKit outside Vision Pro?

Yes. RealityKit runs on iOS, iPadOS, and macOS. If your AR feature or 3D viewer doesn't need visionOS-specific gestures or spaces, you can ship it on iPhone today and bring it to Vision Pro later when scope allows.

Will users get motion sick on Vision Pro? Should we worry?

Yes, and the ones most affected don't always report it. It shapes more of the interaction design than teams expect: reduced motion settings, how content moves relative to the head, where ornaments sit when the user's gaze fatigues. Worth designing around from the first sketch rather than patching later.

We don't want the app to feel like an iPad window floating in space. Can you make it feel native?

Yes. This is the most common reason teams bring me in. Using the room means mixing SwiftUI windows with RealityKit volumes and immersive spaces, handling gestures on 3D entities, and thinking in world coordinates instead of screen coordinates. Apps that skip this step ship an iPad app that happens to float.

How quickly can you start?

Advisory calls can happen within days. For project work, I typically need 1-2 weeks notice to clear the calendar, though I keep some buffer for urgent firefighting. Check the availability badges above for current openings.

Do you work with early-stage startups?

Yes, from pre-seed to Series C and beyond. For very early teams, the advisory tier often makes more sense than project work: you get architecture guidance without committing to a large engagement before you've validated the product.

What's included in the day rate?

Everything: code, architecture decisions, code review, documentation, async Slack availability during working hours. No surprise add-ons. I bill for time spent working on your project, not for "thinking about it in the shower."

We're in a different timezone. Will that slow things down?

I'm currently in Vancouver (PST), with full overlap for North American teams. For UK and Europe, I'm online by their afternoon. For Gulf or APAC, we'd agree on overlap hours and handle the rest async. I've worked with teams from San Francisco to Dubai.
