Live Video Streaming Shopping Application

A React app supporting live video streaming combined with eCommerce. The host app allowed a host to broadcast on the platform and add an additional expert to the video call. The consumer side allowed one to watch the stream and purchase the demonstrated products. The host app was React Native, and the consumer side was React video streaming using Agora.

Real Estate Website
I was the full-stack developer building out this project under a tight deadline. The back end was developed with Node.js using the Hapi framework. The front end was built with Angular 9. We reached the feature level of the incumbent competitors in less than 12 months.

"Virtual Bank" Mobile Application
Created the entire back end for a banking application and assisted with the native Android and iOS builds. The work included building REST APIs from the ground up, connecting to multiple 3rd-party services, and deploying in a PCI DSS-compliant way.

eKYC Platform

Created an eKYC platform in Node.js and native Android and iOS packages on the front end. Ran this as a standalone application that could also be integrated into other applications. The signature of the eKYC record was stored on the Ethereum blockchain for later verification.

Fitness Mobile Application

Built 100% of the application. It was a Facebook Parse back end, iOS (Swift), and Android application. The app rewarded people for completing a certain amount of steps per day. This was done by working with the accelerometers in mobile phones.
