Nemanja V.

I help founders and small product teams build iPhone and Mac apps that feel finished, then keep improving them with a steady release rhythm. I'm Nemanja, an independent iOS developer and design engineer in Barcelona with 10 years in the industry. I work across the interface and the engineering behind it: clear layouts, responsive gestures, thoughtful transitions and dependable native behavior. I can work with your designer or help shape the experience as we build. Recent work: • Recint: founding engineer, building the UIKit/SwiftUI app and TypeScript/Hono backend for fashion discovery and outfit creation. Currently in private beta. • Circlin: founding engineer on a video-first marketplace, spanning native iOS, AVFoundation, GraphQL, payments and shipping. • Metrimus: built the complete native macOS app for a music library product for producers, using AppKit, AVFoundation and Core Data. • Calendly: implemented Schedule in Real Time inside the existing iOS app, working with the established team. • Included Health: contributed to UIKit refactoring and SwiftUI adoption through Vicert. I particularly enjoy consumer products, music and video experiences, and the details that make an app satisfying to use: transitions, haptics, loading states, accessibility and performance. Ways we can work together: • A focused review to find what is holding the experience back. • A paid implementation sprint for one flow, feature or release. • An ongoing product partnership after a successful first sprint, with reserved weekly capacity, an agreed backlog and regular releases. For ongoing work, I favor a short weekly written update, planned check-ins and clear priorities. We agree the scope, response expectations and release goals up front so the work stays focused. Send me your app, what feels unfinished, and what you'd like the next release to improve. We can choose a sensible first step here on Upwork.
