Dear, Manager. I am a software full-stack developer with a focus in React, React-Native and Node development. I have over 6 years experience in web development and have been spending the past 5 years working on mobile apps and mobile-friendly websites. I'm primarily experienced using React Native, providing cross-platform apps for both Android and iPhone in an accelerated timeframe than working in separate languages (Java, Swift/Obj-C). I have worked on a range of projects over the past few years, from marketplace to multimedia. I have experience working with social media login, payment processing, audio/video playback, push and email notifications, and integrating with both server-based (REST API) databases as well as cloud-based (Firebase). I'm also an experienced front and backend web developer using Ruby on Rails, React/ Node and PHP/ Laravel. Via chat, I will share my past projects either codebase or link upon your request. I have more idea to implement your idea using my skill successfully, so I want to discuss with you in detail via chat. Sincerely hope good health for you. Best regards.
