I'm a full-stack mobile application and web developer with 12+ years of experience. My work experiences cover a wide variety of areas such as native cross-platform mobile application development with React Native / Flutter frameworks along with Redux, native Android development with KOTLIN, native iOS development with SWIFT game and VR application development with Unity Engine & Unreal Engine 4, backend development with Node.js, Express, Socket.IO, MongoDB, PHP, MySQL. Android and iOS Development Native support is almost always a must for excellent quality native mobile apps. For this reason, I like to work in Native iOS and Android development, backed by a great community. I have 2+ years of experience with React-Native as well. It was created by Facebook and used by many industry-leading companies for apps like Shopify's Arrive, Walmart, Bloomberg, SoundCloud, Instagram, Uber, etc. Working with Native tech stack allows quality development for both iOS and Android, keeping intact the app's performance even in complex situations and giving an extra edge for the scalability of the applications in the future. Working with React Native allows rapid development for both iOS and Android simultaneously, cutting development expenses to half and still resulting in close to native end-product. Back-end development Many of the features an app might need a backend server, e.g., user authentication, communication, payments, etc. I work with Node.js, Express, Socket.IO, and MongoDB. These technologies are great for developing a lightweight but robust backend. UI/UX Design A good app idea isn't everything. It has to look clean, modern and the user experience has to be fluid. There are two primary reasons for this. First, to catch the potential user's attention. Second, keeping up their interest in providing a smooth user experience. People will always look for the most comfortable solution to their problem, and with the lack of good design, it might be the competitor's product. Got an app idea? Feel free to contact me for a free consultation!
