    Hi, you would love to work with me, a friendly developer who is responsive (I reply my clients in minutes) with a solid foundation in modern front-end technologies and a passion for crafting intuitive mobile experiences, I am excited about the opportunity to contribute to your project’s success. ⚡Bonus disclaimer: I also do native iOS/Android development , so any chance you want to migrate to another tech stack or need to dive deep to native platform you can count on me. Here is how I can help you with my 6-year experience in React Native development: • I've worked on 2 projects that has more than millions users. • Producing responsive screens and visual components from design materials, then hook them up with backend endpoints. • Integrating application logic with 3rd-party services or SDKs. • Configuring app distribution using Diawi (Test), TestFlight (Staging) and Apple Developer (Production). Optionally, I configure a mobile CI system that automates app deployment using Fastlane over Bitrise (Cloud) or Jenkins (On-premise). • Last but not least, I know Apple and Google submissions guidelines in-and-out, tips and tricks on how to by-pass to get your app approved faster. • These daunting experiences should be familiar to me, who has spent the last 6 years working with various modern mobile app frameworks, and finally in love with React Native. My portfolio contains entirely of React Native projects, which is my most favorite framework in my career as a mobile frontend developer. Since 2017, I've been heavily using React Native to build dozens of business-grade mobile apps that leverage social media systems, e- commerce, payments, multi language chat/messaging portal, map-based/location-based/anything-based.... Yet I still feel intriguing about your innovate product and want to explore more if have a chance. I live in ICT timezone (UTC+7) but I am pretty flexible to adjust to different time zones (AU/ EU/ US markets) to accommodate client's needs. On top of it, I always keep my clients updated via daily reports so that they easily keep track of progress. I am available via e-mails and in messengers for anything urgent. Regard Gio Na Le

    I am an enthusiastic React developer, who always works with full passion and responsibility. I’m very strong in web & mobile development. - I've worked with ReactJS, React Native, Redux, GraphQL, Functional( Ramda ) and Reactive( Rxjs) Programming. I could use Recompose, Styled-components to create beautiful Component, and Reselect and Normalizer for good redux performance. - Unit testing with Jest and Enzyme. I could take advantage of TDD approach in which I believe mocking is not good for TDD. - Have worked in many mobile features: Animation Chart, Maps, Push, Voice Recorder, Rich Text Editor, Animations, Speed to Text, etc - Very strong in Redux/Flux or pure architecture. Have used redux-saga, redux-observable, redux-thunk - Very good for building heavy animation. - Strong in integrating with Restful, GraphQL. - Use Flow-type for type checking and Prettier, ESlint for code format. Also, work with Typescripts, Tslint as well. Now Typescripts is my favorite tool - Continuous Integration, Delivery, and Deployment with GitLab CI, Fastlane, etc - Update the app on-the-air with CodePush. - Strong in writing Native Modules for both iOS and Android (5+ years in mobile development).

    So, you’re looking for a Full-stack developer to help you build an idea to completion with high scalability and availability? I have built a CMS platform for bloggers, which has over 40 sites (domain) and more than 3M views per month. As a Senior Fullstack Developer, I have designed databases, and architecture source code and improved it day by day. I also have applied design patterns, use microservices, clean code, and kept code maintainability. I have a passion to build products. Unlike many other developers who only try to do the job as much as possible, I focused on building a useful product for users. Proven ability to take an idea to completion So anyway. Here’s what I can provide: • Architecture and building a production Application from scratch – I hope that my efforts to create useful products for users. • A long-term relationship - I can join a team or build a team that can be scaled to develop the product. • Always try my best to deliver on time - I am a very strict person with deadlines, so I will break down tasks to estimate exactly and apply Scrum, separate sprint, using Jira to track tasks. So here are my skills: 1) Javascript, Typescript Experience with framework ReactJS, NodeJS: I have many years to using Javascript and Typescript language. The main framework which I have used: NodeJS, ReactJS, NestJS, NextJS to build frontend and backend. I was interested in NestJS on Backend. I can use OOP knowledge and apply design patterns to it. Especially, it is great to support microservices. On the front end, NextJS is wonderful. It is the best framework to support SEO because I can choose between Server-Side Rendering (SSR) or Static Generation. 2) DevOps: Docker, Kubernetes. I am not the best at admin systems but I can deploy production on Linux. Additionally, I have experience using Docker and Kubernetes to manage microservices. Finally, if you don’t like my approach to resolving problems, I think we are not a good fit. But if you want to hire me, you will not regret it. Leave me a message, and you will love my way of working!
