    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. If you're wondering if I am familiar with the functionality you need for your project, here is a (very) incomplete list of keywords: ✅ In-app purchases, RevenueCat ✅ Maps, location, geocoding ✅ Login with email, Google, Facebook, Apple, phone number ✅ Camera, Gallery ✅ Audio, Video ✅ Charts ✅ Firebase, Firestore, Crashlytics, Analytics, Dynamic Links, Cloud Messaging ✅ Push notifications ✅ REST APIs, OAuth 2.0, PKCE ✅ Data Matrix, QR codes ✅ Contacts ✅ Support and maintenance Let's get in touch and see if we're a good match.

I always strive to be the best individual that I can be and take every challenging opportunity as a chance to learn and grow. Couple of reasons why hire me: * Unlike other great developers, I know how important it is to keep an open communication channel, updated you for a single update on time, finish products on or before time. * I've started developing mobile applications 10 years ago. By now, I was exposed to different areas of science (not only computer science), so when you need not only a coder, but also someone that thinks logically/analytically, I'm your guy. * Even though my rate may seem high, I can assure you that I'm efficient and spending time purely on planning and development. I'm never charging for anything not directly connected with project.
