    Need help building or maintaining a feature-rich Swift mobile app? Or overcoming challenges with legacy code like Objective-C? Trust me to be your go-to mobile developer — I'll take care of all your technical concerns. ⭐️ I’m Nik, and I live and breathe software development. I’ve worked with big brands and startups alike. Been a part of large and small teams, and even supported apps as the sole developer. Seen success and failure in the mobile market, and taken away important lessons I’ve incorporated into my service offering. I love getting my hands dirty with code and testing. But I’m also passionate about higher-level efforts: hiring the right technical talent; defining architecture; liaising with engineers, QA teams, and product owners; and ensuring projects are on track for a successful launch. So whether you need someone to help put together and lead a development team, or just need a talented developer who can collaborate with other technical professionals for additional support, I’m your guy. Whatever your specific case, I’ll make sure to keep you in the loop about progress (always available for a call or chat!), and deliver features as expected and on time. But development work can be hard to grasp sometimes, even for technical people. So to be clear, here’s how I can help you: • Add features and fix bugs reported by customers and QA teams for programs operating on legacy code (e.g., Objective-C). • Build a mobile app from scratch on iOS/Swift, Android, or another mobile development technology. • Develop a prototype or MVP for investment consideration or beta testing. • Advise on proven best practices in iOS development, and set up an efficient development process. • Consult on other app development challenges. 🙍‍♂️ WHAT CLIENTS THINK 🙍‍♀️ Want to know more about me? Well, generally I’m not a fan of talking about myself (who is?), so I’m grateful to have happy clients who have shared their memorable experiences about working with me: "Nikita's work ethic is fantastic. He [thinks] outside the box, and will advise on solutions and best practices. If I had to mark his skill set out of 10, I would give him an 11. I look forward to working with him again in the future." – Client who needed a developer with iOS, Android, and Windows skills "Nikita is one of the best iOS developers on Upwork. Talented, knowledgeable, efficient, and very professional. Great communication skills and adheres to deadlines […]. I enjoyed working with him." – Client who needed a senior iOS developer. "Nik is an unbelievable multi-stacked programmer. He produces high-quality work and has a good eye for detail. I will be using him for future mobile app development." – Client who needed iOS/Swift and Android development skills 🛠 TECHNICAL EXPERTISE 🛠 As a final note, here are a few of the key technologies and technical areas I have deep expertise in: ✅ Apple ecosystem (iOS, native iOS development, Swift, macOS, watchOS, tvOS, etc.) ✅ Swift, Objective-C ✅ Android, Java, Kotlin ✅ ReactNative, Redux, JavaScript, TypeScript ✅ MVC, MVVM, VIPER ✅ Reactive programming (ReactiveCocoa, RxSwift, RxJava) ✅ CoreData, SQLite, Firebase, Realm, MongoDB ✅ In-App Purchases ✅ Unit-testing, functional testing, UI testing ✅ Continuous integration and continuous delivery SaaS and standalone solutions ✅ Linux server administration && database administration ✅ Server-side and API service programming: JSON, XML, Swagger, Python, Django, Ruby, Rails, PHP, Erlang, Haskell

    Time is the coin of your life. It is the only coin you have, and only you can determine how it will be spent. Be careful lest you let other people spend it for you. -- Carl Sandburg Written in the previous century as poetry about time, it also succinctly summarizes my attitude towards technology. I am always on the lookout for the most efficient method to achieve any given objective. This implies that I not only have a willingness to learn new things, but also I can let go of the familiar if it has been supplanted by something superior. I have 2 decades of applied computer science experience in which I've dabbled in nearly all its domains; linux, windows, MacOS, workstation, server, infrastructure, databases, virtualization, programming, scripting, and reporting are all within my purview.
