Build Angular/React based real time web application on cloud

I need help with a few proof of concept projects. It would be a web based (Angular/React) application with real time data price feed from APIs, and micro service price simulator service we develop and host on the cloud. The hire would also need to know the pieces to the devOps process, container tools and unit testing. I am a tech lead myself so part of the work is walking me through the design/architecture/code so I can pitch the application to my clients. I can discuss more details on my current and future plans, pay, timing, coordination etc.
