Go Bank

This application is primarily intended for exploring technical concepts. My goal is to experiment with different technologies, software architecture designs, and all the essential components involved in building a monolithic-based application in Golang.

Features

• Building RESTful APIs using the Gin framework for handling HTTP requests
• Leveraging gRPC for efficient internal service-to-service communication
• Secure authentication using PASETO tokens and JWT
• Asynchronous task processing with Redis and Asynq for background processing
• Reliable database operations with PostgreSQL and pgx driver
• Type-safe database queries with SQLC
• Database migrations using golang-migrate
• Input validation using go-playground/validator
• Structured logging with zerolog
• Configuration management with Viper
• Testing with testify for assertions and gomock for mocking
• Containerized deployment with Docker and docker-compose
• Deploying to production environments using Kubernetes on AWS EKS
• Automatic SSL/TLS certificate management with cert-manager and Let's Encrypt
• CI/CD pipeline with GitHub Actions
