Roman B.

Senior iOS Developer | Swift, SwiftUI, Objective-C, AI Integration

I'm Roman, CTO and founder of Define Solutions. Since 2016, we've shipped more than 200 mobile projects generating over 15 million downloads across the App Store. Over the years, we've built products across almost every category: fitness and health tracking, healthcare platforms, GPS and navigation systems, marine navigation applications, mapping and location-based services, entertainment and lifestyle products, news and media platforms, music streaming applications, restaurant and food ordering systems, e-commerce stores, social networks, messaging platforms, e-readers, marketplace applications, iPad products, Apple Watch companions, and CarPlay integrations. Beyond traditional mobile apps, we've delivered AI-powered experiences, recommendation engines, subscription-based products, payment integrations, real-time communication features, complex backend integrations, and highly scalable enterprise systems. We've worked with startups building their first MVPs, established businesses launching new products, and large organizations developing both internal operational tools and customer-facing applications used at scale. Some projects start with a detailed specification. Others arrive halfway through development after a previous team couldn't deliver. We've successfully handled both. One thing you learn after 200+ projects is that writing code is only a small part of building a successful app. The projects that launch smoothly are the ones where requirements are clear, technical risks are identified early, App Store constraints are considered from day one, and everyone agrees on what success looks like before development begins. That's why every engagement starts with understanding the product, validating the scope, and identifying potential challenges before a single line of code is written. Whether you need a new iOS app, help finishing an existing project, or guidance on architecture, scalability, AI integration, App Store launch strategy, or modernizing an existing codebase, I'd be happy to discuss it. Send me a message and I'll tell you honestly whether we're a good fit and what it would likely take to get your project delivered.
