Can you tell about the tasks and functions you implemented in your last project?

In my last project in Go, I implemented several key functions:

• Developed a REST API for managing user data using the standard net/http library.
• Implemented request handling with input validation and returning appropriate HTTP statuses.
• Configured interaction with a PostgreSQL database using the database/sql package and the pq driver.
• Added logging and error handling to improve the reliability of the service.

Example of simple HTTP handling:

http.HandleFunc("/users", func(w http.ResponseWriter, r *http.Request) {
    if r.Method != http.MethodGet {
        http.Error(w, "Method not allowed", http.StatusMethodNotAllowed)
        return
    }
    // Logic to retrieve users
    w.Write([]byte("List of users"))
})
