cryptozoo, a web3 marketplace

Implement all the back end code for the project from scratch (node.js, Typescript), including our own node in the blockchain.

Create all the infrastructure in AWS using only serverless components (SNS/SQS/Aurora Cluster/ECS/ Lambda/Redis). The infrastructure is fully IaC using the serverless framework. Continuing on the infrastructure area I created the CI/CD pipeline using circleCI, and quality controls (e.g  code coverage) metrics for developers using sonarCloud. Additionally I created the automated monitoring system, using cloudwatch alarms and fan out to slack channels.

There are too many I's above; the truth is while I was the first engineer in the company, we grew, so I shifted my focus on hiring new developers, sharing knowledge, review PR, mentorship, describing the big picture and helping them achieving their goals.
