About

I'm a multiple-time awarded Flutter Developer (with 7+ years of experience) with a solid Design background (10+ years of experience). My primary language is Dart, but in my portfolio, you can also find projects written in Swift, TS, Obj-C, etc. The core concepts of programming matter more to me now than the exact phrasing in a particular language. In my current job, I also mentor other Flutter devs and provide solutions for the architecture solutions in our apps. Previously, I showcased my skills through the official Flutter competition wins, but now I prioritize family & open-source (I have accumulated hundreds of stars on my GitHub) in my free time. If you want to learn more, please feel free to reach out! Fun fact: according to CodersRank.io — I'm in the "Top 4" Worldwide Dart Developers list: https://profile.codersrank.io/leaderboard/developer?technology=Dart
