Project History
TipTapGo
This 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.

Social Networking App — S'More
S'More is the world's first relationship network designed to connect singletons beyond a headshot.
It reveals your photos to your matches only when they chat with you. Also, video is initially blurred and will get clear as you spend time with them via video chatting.

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.
