Experience
Facebook Messenger Bot
I led a team of developers to build a Facebook messenger bot for allowing users to order ahead at their favorite food trucks and restaurants.
The implementation involved a Node.js application using both MySQL and MongoDB. The back-end service handled the payments via Braintree, served the application via AWS, and stored data for orders, menus, and user information in MySQL and MongoDB databases. The Facebook messenger bot allowed users to send their location to find food trucks/restaurants nearest them and served location/hour information to users. Also, the UI provided detailed menus of the desired restaurants which were showcased with the available Facebook messenger UI elements.
Moreover, with partnerships with food trucks, we were able to integrate a native mobile application to help food trucks/restaurants accept orders in real time and begin serving orders immediately. Additionally, from a maintainability perspective, we custom built our own auto deployment pipeline using Git, Bash, and CircleCI to run our tests before automatically deploying the newest version of our code base to AWS to provide the newest features/functionality to users.
