I mainly worked around the Typescript ecosystem, with Express on the backend and React on the frontend. In terms of infrastructure, I used DynamoDB a lot as a non-relational database, PostgreSQL as a relational database, AWS API Gateway, EKS to manage microservices and AWS SQS in conjunction with AWS Lambda for asynchronous processing. From the moment I joined the company, I added a lot in terms of code organization, creating templates for lambdas, express microservices and infra-as-code.
A freelance where a homepage and a system were developed for two architects from my city. They wanted something that represented them but at the same time could add new projects that would serve as a kind of portfolio for future new clients.
