TipTapGo
https://apps.apple.com/us/app/tiptapgo/id1195878373This application allows users to tip service providers, such as waitresses and bartenders, easily.
The application will search nearby service providers, let users select one, and give a tip.
Service providers will have either a mobile application, like a service-provider app, installed on their phones or wear a BLE-powered bracelet designed by TipTapGo.
This way, the customer's app will search and pair with the provider's application, and payment is made between the two.
ROLE AND RESPONSIBILITIES
- Made significant decisions regarding the system architecture.
- Built iOS and Android applications.
- Helped develop web admin console in Angular 10.
- Applied Agile methodology to break down into sprints and manage iOS,
Android, web, and back-end development deadlines.

Good Eggs
https://apps.apple.com/us/app/good-eggs-grocery-delivery/id1020495070I helped move the codebase toward a new architecture, using ReSwift and VIPER to iterate more rapidly on features. One notable feature I built was the ability to preorder for various holidays and events for which the company sets up special preorder availability.
A part of maintaining and iterating on the app, I was also iterating on the back-end API that coalesces requests from the iOS app and proxies them to the central application server. For full-stack features, I worked on all three codebases.
