I built the entire platform's infrastructure and backend from the ground up. The main goal was to ensure scalability. To do this, I recommended the use of AWS Lambda, FaunaDB, and Pulumi (IaC) as the core technologies. This has so far ensured the system can withstand high levels of burst activity and fault tolerance (due to the nature of serverless infrastructure). To date, I lead a team of developers, continue to do development work across the entire stack, and run workshops to align client expectations.
