- Set up a multi-Docker container deployment on AWS that used a CI/CD pipeline and rolling updates. Used many AWS services such as CodePipeline, CodeBuild, Elastic Beanstalk, RDS, S3, ECS, and ECR.

Coinbase Commerce Integration
Coinbase is one of the largest cryptocurrency marketplaces in the world. I was assigned to build their official Prestashop integration that handles transactions with their Coinbase Commerce product for eCommerce stores on the Prestashop platform.
Treerating
Built a service that integrates with eCommerce stores and collects customer reviews about their shopping experience using Python, Django, and MySQL.
The eCommerce website installs a module for their platform or makes their own HTTP calls to Teerating's API with their customer's data and Treerating will then, in turn, collect a review from the individual.
The eCommerce website also uses the API to get their aggregated score and rating from their customers, which uses Schema.org formatting that allow the website to get a rating in the search engine result pages.
