Learn to design, develop, and deploy a complete backend system from scratch using Golang, PostgreSQL, and Docker in this comprehensive master class. Explore database schema design, SQL code generation, Docker installation and usage, database migration in Golang, CRUD operations, unit testing with random data, database transaction implementation, deadlock handling, isolation levels, and read phenomena. Set up Github Actions for automated testing, implement RESTful HTTP APIs using Gin, manage configurations with Viper, and mock databases for thorough API testing. Dive into secure password storage, token-based authentication with PASETO and JWT, and implement login functionality. Create minimal Golang Docker images, use docker networks and docker-compose, and deploy to AWS services including ECR, RDS, and EKS. Master Kubernetes architecture and deployment techniques while gaining hands-on experience with essential backend development concepts and tools.
