    So you are looking for React Native developer to develop high-performance apps? I'm a React Native developer and I've worked in this industry 5 years What can I do? 🔹 With a lot of experience working with re-animation, I am confident that I can increase the app performance and make a smooth animation. 🔹 With a strong knowledge of Typescript, I alway define clearly type help the project more make seen 🔹 Create the Native Module for special required need native code (Java/Objective-c) 🔹 Help you upgrade the algorithm/ logic/ solution Unlike many other developments that try to complete the project as FAST as possible so they can take the money and disappear. I will spend more hours researching the code and the business after understanding this I can generate SOLID code to make the project clean and extensible. Definitely, you don't have to pay me a single cent for this I'm not saying I'm the best in the industry but I'm probably the only person who will do there 5 things for you: 🔹Go the extra mile, I will spend my time researching the requirement so that I can understand what. you need and want 🔹 I'm not the kind of 9-to-5 person who was just waiting until 5 pm to shut down the laptop. Working extra hours to help you achieve what you're looking for is my big hobby 🔹 To follow up between me and you, I will send you a report of what you did yesterday and what I will do today it will help you to know the progress of the work 🔹 Sometimes we don't have the same time zone, but I can assure you that when you have any questions I will reply to you as soon as possible 🔹 In the meantime for the maintenance/ development projects If I found any "hidden bug" I will raise this for you. I don't want after we close the project the application to have any strange bug After a few years of working with React Native, I realized the following has a huge impact on the quality of the app: - When I maintain a Typescript project I see some developers always use any type for interface or type, why ?? here is a worry if they don't want to specify the type of reason why they use Typescript?. For me, type is very important, it will help make developers more efficient, especially when dealing with large, enterprise-scale codebases. - With React Native we only create one code to be used for both platforms (Android/IOS) that's React Native's strong point, but some "lazy" developers use only one device or one platform as a developer so they don't test multiple devices and both platforms sometimes the UI will be correct there but in client-side is not correct (especially the difference between iPhone 6 and iPhone X)\ - Talking about app performance, some React Native developers don't know much about React Native then they can't control the performance of the app worse than they don't care about it. In the beginning, the app doesn't have a lot of data and features so the app will be fine but as we scale the app we ran into terrible problems with performance 📣 if we work together, you just need to provide me the business, product/service, and requirement documents you want, answer some questions that I might have and I'll do all the rest. 📣 If the final result is not what you're looking for, don't pay me. I'm happy with that. Not once have I questioned taking money from someone who is not with my job If you are interested in what I have to say, just contact me and I will discuss it with you more 🎯🎯🎯

I am proficient with using either native languages (Swift, Java) or cross-platform frameworks (ReactNative, Flutter). Having a broad knowledge of these technologies allows me help clients in making decision to select the most suitable solution for their idea. Should we always use ReactNative/Flutter to cut development time and save cost? Should we always use native to achieve the best performance? Those are questions that I can answer for you. Not only I can develop applications based on the specs, but I also work closely with clients to help them define their specs. I can participate in all stages in the app development, from clarifying requirements to publishing to App Store/Google Play.
