OVERVIEW OF THIS PROJECT

Here are some of the things that I have dene in this project:

• I've done a lot of work on the database layer. This is important, as the database is the foundation of any application.
• I've also implemented a number of security features, such as JWT and PASETO tokens, authentication middleware, and authorization rules. This is important for ensuring the security of your application.
• I've used a number of different technologies, such as Go, Postgres, Gin, gRPC, Swagger, and Redis. This shows my expertise with a wide range of technologies and can use them to build a production-ready application
• I've also automated a number of tasks, such as building and pushing Docker images, deploying to Kubernetes, and issuing TLS certificates. This shows that I'm using modern DevOps practices to build and deploy your application.
