✅ Task Manager API in Go

A simple and lightweight Task Manager API written in Go. This project uses an in-memory database and is structured using a feature-based architecture. It is ideal for learning purposes and rapid prototyping of RESTful services in Go.

✨ Features

• 🗂️ Task management with basic CRUD operations (extendable)
• 🏗️ Feature-based project structure for scalability
• 🔐 User authentication using JWT
• 🌐 HTTP server built with Go's standard net/http package
• 💾 In-memory data storage
