Custom iOS UI & Animation Development
Pixel-perfect SwiftUI from a Figma file, gesture-driven interactions, custom transitions, and design system components your team can reuse. I've shipped 12+ apps with distinct visual identities — the UI is the product in most of them.
- custom SwiftUI components and reusable design systems
- complex animations: springs, keyframes, matched geometry, phase animators
- gesture-driven interactions: drag, pinch, rotation, long-press with haptic feedback
- Figma-to-production implementation with pixel-level fidelity
What clients say
"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

Common engagements
Build the UI from a design file
You have Figma screens. I turn them into SwiftUI with the animations, transitions, and micro-interactions the designer intended. Typical timeline: 2-6 weeks depending on screen count and interaction complexity.
Design system for your iOS app
Reusable component library in SwiftUI: buttons, cards, inputs, navigation patterns, colour tokens, typography scale. Your team builds new screens from the system instead of one-off layouts.
Fix an existing UI that doesn't feel right
Janky scrolling, stale animations, layout breaking on different screen sizes. I profile with Instruments, find the bottleneck, and ship the fix.
Questions
Who can build pixel-perfect SwiftUI from our Figma designs?
Yes, most of my UI work starts from a Figma file and a call with the designer. I've shipped 12+ apps with distinct visual identities, including calculator-disguise UIs and 3D spatial interfaces, so bespoke and gesture-driven work is the normal case for me. A set of 5-10 screens is 2-3 weeks; a full app with custom animations and a reusable component library is 4-8.
Can you work from our Figma / Sketch / Framer files?
Yes. Most of my UI work starts from a Figma or Sketch file and a call with the designer. Framer prototypes are useful for communicating motion — I match the feel on device. I flag anything that won't translate cleanly to iOS before building it.
Do you build in SwiftUI or UIKit?
SwiftUI by default. UIKit where SwiftUI has gaps — certain scroll behaviours, text layout edge cases, or performance-critical rendering. I bridge cleanly so the codebase stays consistent.
Can you match a specific design system or a custom brand?
Yes. Custom brand guidelines are the normal case — I've shipped apps with calculator-disguise UIs, 3D spatial interfaces, and voice-call interfaces. If you have a Zeplin or Storybook spec, I can work from that too.
How long does a typical UI project take?
Depends on screen count and interaction complexity. A set of 5-10 screens with standard interactions: 2-3 weeks. A full app with custom animations, gesture-driven navigation, and a reusable component library: 4-8 weeks. I scope from the Figma file.
Do you handle all screen sizes and orientations?
Yes. I test on iPhone SE through iPad Pro, including Dynamic Island layouts, Stage Manager on iPad, and landscape where applicable. Adaptive layout is part of the build, not an afterthought.
Are you an agency, or do we work with you directly?
Directly - you're hiring me, one senior iOS engineer who writes the code, rather than an agency that routes you through a project manager and a team you never meet. For a lot of my clients that's the whole point: one person who owns the work end to end.
How quickly can you start?
A quick call can happen within days. For project work I usually need 1-2 weeks to clear the calendar, though I keep some buffer for urgent firefighting.
Do you work with early-stage startups?
Yes, from pre-seed to Series C and beyond. For very early teams, a short advisory engagement often makes more sense than a full build: you get the architecture guidance without committing to a large piece of work before you've validated the product.
What's included when we work together?
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.
