Hire the Best Android Developers
in Romania

After a decade in scripting and automation, I turned to mobile development and game design. I specialize in 2D, lightweight UI for idle/clicker mobile games. I am excited about the latest developments around AI and vibe coding, heavily using Gemini and Claude models in Google's Antigravity to craft feature-rich UI/UX for production grade apps. If vibe coding opens new horizons to non-technical users for fast prototyping, add in the mix 12 years of hands-on coding experience on real-world solutions and you have me. My service offer includes orchestrating agentic AI on medium to large projects for mobile development, overseeing the entire workflow from start to end, to make the most of LLMs have to offer. This means reduced costs and aggressive deadlines. Full stack support and modern UI/UX experience with Kotlin, Material 3, Firebase, Supabase, Jetpack Compose, MVVM architecture, coroutines. Other relevant experience: Angular, React, Node.js, Python

I have 13 years of experience in mobile app development and 4 years in Flutter development. I have created around 15 MVPs from scratch for various satisfied clients. I am Top Rated Plus on Upwork and my work history is impeccable. I believe that I am currently in the top 1% on this platform. My preferred projects are the ones that have precise design specs (Figma, Adobe XD) and clear use cases, so I can jump right in and code. I use best coding practices in my work, and I write clean and maintainable code. I also provide UX/UI feedback along the way. I usually set up a continuous integration/deployment flow (CI/CD) so that you get instant access to the app's progress and we can iterate fast and efficiently.

Co-founder of TMZ Software, a mobile app development agency rated 5.0 on Clutch. Android engineer by background, shipping to Google Play and the App Store since 2015. 🤝 WHY CLIENTS CHOOSE ME ✅ You work directly with the engineer writing your code.
