I’m a Mobile Engineer focused on building modern, scalable, and user-friendly mobile applications using Kotlin, Swift, Jetpack Compose, and Firebase. Over the past few years, I’ve developed Android applications across healthcare, education, social media, food ordering, and productivity industries. I’ve also built and launched my own startup app, WakeBit — an anti-snooze productivity app that reached 2,600+ users on Google Play. My core stack includes: • Kotlin • Jetpack Compose • Firebase • REST APIs • MVVM / Clean Architecture • Coroutines & Flow • Room Database • Hilt Dependency Injection I can help with: • Full mobile app development • Modern UI/UX implementation • Firebase & backend integration • REST API integration • Bug fixing & performance optimization • Architecture improvements • Google Play Store deployment Projects I’ve worked on: • WakeBit — Productivity & alarm app • Ask Medy — AI-powered healthcare assistant • Musofir Uz — Russian patent exam preparation app • Food ordering platforms • Hospital management systems I also have experience collaborating on iOS UI redesign projects and working in fast-moving startup environments where speed, product quality, and user experience matter. I care about building apps that feel smooth, polished, and reliable for real users. I communicate clearly, learn quickly, and enjoy turning ideas into real products. Let’s build something great together.

I build cross-platform applications across games, mobile, and desktop, with a focus on performance, stability, and production-ready architecture. In game development, I work with Unity and Unreal Engine to create interactive experiences, real-time systems, and simulation-driven applications, including gameplay mechanics, UI systems, and performance optimization. My work often involves handling real-time rendering, physics, and scalable game logic for both standalone and connected environments. For mobile, I develop applications using Swift and Kotlin for native performance, and React Native and Flutter for cross-platform delivery, ensuring consistent UX across iOS and Android. I’ve built apps ranging from consumer products to data-driven tools, with strong attention to responsiveness and maintainability. On the desktop side, I use C++ and Electron to develop high-performance applications and custom tools, including system-level utilities and UI-driven software. I focus on efficient resource management, clean architecture, and seamless integration with external services and APIs. My approach is to deliver reliable, scalable solutions that perform well under real-world conditions, whether it’s a game, a mobile app, or a desktop system.

But, when I dig deeper, I find that most of the time it's one of these 3 reasons. 👉🏼 𝗚𝗲𝗻𝗲𝗿𝗮𝘁𝗲 𝗺𝗼𝗿𝗲 𝗿𝗲𝘃𝗲𝗻𝘂𝗲 for their existing business or build a new business from their IDEA. 👉🏼 Expand business or 𝗮𝗰𝗾𝘂𝗶𝗿𝗲 𝗻𝗲𝘄 𝘂𝘀𝗲𝗿𝘀 through digital platforms. 👉🏼 Deliver 𝗱𝗲𝗹𝗶𝗴𝗵𝘁𝗳𝘂𝗹 𝘂𝘀𝗲𝗿 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 to existing or new customers. Now, comes the HARD part. How do you make sure you've hired the right developer or team? Everyone claims they are great with different certificates, portfolios, skills, etc. Maybe they're right. But how do you verify? It's extremely difficult to be 100% certain that you've hired the right team until you work with the developer or a team for a few weeks. You might be thinking what's the solution? Here's our offer. Let's do the initial consultation call and see if we're a good fit for you. If you think we are, let's make a small commitment of two weeks. 𝗜𝗻 𝘁𝘄𝗼 𝘄𝗲𝗲𝗸𝘀 — 𝗮𝘁 𝗮𝗻𝘆 𝘁𝗶𝗺𝗲, 𝗶𝗳 𝘆𝗼𝘂 𝗳𝗲𝗲𝗹 𝘆𝗼𝘂 𝘄𝗼𝗻'𝘁 𝗴𝗲𝘁 𝘁𝗵𝗲 𝗿𝗲𝘀𝘂𝗹𝘁𝘀 𝘆𝗼𝘂 𝘄𝗮𝗻𝘁, 𝘆𝗼𝘂 𝗱𝗼𝗻'𝘁 𝗵𝗮𝘃𝗲 𝘁𝗼 𝗽𝗮𝘆 𝗮 𝗽𝗲𝗻𝗻𝘆.

So you get on the ride with us and see if everything we say on this website is true and valuable to you. Then, if it is, that's when you decide to keep it. If not, no hard feelings. By working with us for two weeks, you will be able to make an informed decision that this isn't for you. But you can't make that decision right now for the same reason you don't buy a car without a test drive. And remember, whether it's 79 minutes or 79 hours from now, if you ain't happy, we ain't happy. For any reason whatsoever, if you want your money back you can get it because we only want to keep your money if you're happy.
