    I'm a Brazilian Mobile and WEB Developer. I have experience in cross-platform development using Flutter. It has been my main technology for the last couple of years. Besides Flutter, I have good experience in Web and Android Development, besides basic knowledge of IOS. I'm currently an Upwork Top Rated Plus Freelancer, which means I have a great rating history and success in both short and long-term jobs. When I have to design a mobile app all by myself, I usually will use Flutter to develop the mobile app, NojeJS or PHP to develop the API, and MySql to store data. My first job was as a mobile developer, at Lemon Inteligência (a small company in Brazil), it was where I started using Flutter. While I was working for Lemon, I got a part-time job at upwork.com, as a Flutter Developer, working for an Australian Company. After some time, I decided to quit my job in Brazil and dedicate my time to working with Upwork. Working with Upwork, I've built a new skill set. Now I'm able to design an entire system using AWS, for example. Also, I've got experience with CakePHP, NodeJs, WordPress, best coding practices, teamwork, etc. Although developing mobile apps using Flutter has been and probably will still be my best skill for some time, I'm always keen to learn new technologies and improve my knowledge. I've developed many different types of systems and I'm sure we would do a great job together. I'm available to chat anytime if you would like to ask questions about my skills and/or your project.

    Hi, I am Umesh Shrestha. I mainly develop cross-platform mobile applications with Flutter. And I also develop a backend for web and mobile applications exposing Rest APIs. I have a bachelor's degree in Computer Engineering. And experience with the software development process. I strongly agree in good communication is the main key to a successful project so I am very flexible with the timing, considering the different time zones. I have been developing cross-platform apps using Flutter for more than four years. And as of now, Flutter is supported by six different platforms. I have worked on almost all of the platforms with Flutter. I'm working as a Head of Mobile Development, so creating the architecture, code reviewing, mentoring, and integrating best practices is a part of my everyday job. I have worked on different native platform APIs for iOS/Android as well as many different third-party APIS. For example: camera API push notifications deep linking maps (google map and OpenStreetMap) audio and video manipulation Revenuecat and Google in-app purchase in-app updates and in-app reviews Social logins with Facebook, Google, Apple, and LinkedIn. Firebase and Firebase-related products like firestore, firebase analytics, firebase storage, firebase hosting, and more. Google Sheets and Google Drive API are integrated within an app and many more as per project requirements.
