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.
