    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
