Experience
New York On Air
https://www.flynyon.com/One of the brand's sites for New York On Air, "FlyNYON". I built the API that this site runs on which handles everything from flight management to payment processing.
Fitplan
https://www.fitplanapp.com/Working with their designer, I built Fitplan's website in React and Node.js. It supports multiple languages and also has a recurring subscription and billing system which I also built.
The recurring subscription system was very valuable to the company because it saved them from paying 30% fees to Apple for subscription made through their app.
