I am an expert mobile app developer in the top 1% of contractors on Upwork. Using React Native, I create well-designed, beautiful cross-platform mobile apps. I love React Native and have been using it to develop a variety of apps for clients ever since it came out. I am a computer science graduate from Azusa Pacific University, and won the hackathon there for one of the apps I made with React Native in under 72 hours. I am easygoing and enjoy working on interesting projects on the cutting edge of technology. I like working with other people, trying to bring their vision for apps to come to life. My most common workflow is Trello, Slack, Github, VSCode, Powershell, Expo, React Native, Firebase. I post daily updates on my progress, as well as over-the-air updates so that you can physically see on your device the progress being made. I always write out clear proposals before committing to working on a project. My code is almost always re-usable, which allows me to make new apps much quicker. At this point I basically have my own library of components to build with. React Native itself allows modular code reuse which helps with this. I've built apps from scratch for clients lots of times, and each time I get better at it. I can give accurate estimates and recommendations because of this. There's also some neat coding tricks I've picked up along the way. I am very flexible with time schedules, app requirements, and so on. The way I'm able to do this is by preferring firm-fixed price, and by starting with the smallest possible version. I enjoy making apps, so if you have an app idea and want it made, let me know and I'll do my best to help get it made. Whether that means me giving recommendations on how you can build it yourself, or me guiding a more junior developer I put you in contact with, or I end up giving a free consultation, I'd love to hear about your app and see if I can help.
