SlideOnline

This is a full-stack Project for a start-up company where I was the chief technology officer.

During the Covid-19 pandemic, and all the lockdowns, the application was to provide users the ability to do online events

features include:

- Custom Dashboard with analytics

- Authentication

- Live Event viewing

- Stripe Integration

- Expo ( Event organizers can run ads on the event )

- Backstage

- Question and Answer ( Q & A )

- Chat ( group & individual )

- Live video chat ( Organiser with up to 25 speakers )

- Breakout rooms ( Mini video chat between attendees based on a topic set by the organizer

and many more

This is one of the most comprehensive and toughest products I have had to build in my career

The frontend was built with React & Material-UI. I used Express.js and Node.js for the backend and Sequelise for the ORM

I initially started out using MSSQL, for the database but switched to PostgreSQL because of its versatility.

I built a very resilient Cloud infrastructure on AWS using Elastic Beanstalk and load balancers.

For the video calls AWS Chime SDK

and for the chat and polling, I used Firebase

For the streaming, I used docker, FFMpeg, and AWS Lambda.

and Mux to stream the event for the attendees,

In the Backstage the speaker and the invited guest could also chat and have a quick call before going to life

I added an extra feature so organizers can live stream on their socials too like Facebook.
