Tell me about your experience working with Go and the tasks you faced.

In my work with Go, I have dealt with developing high-load microservices and real-time data processing systems. The main tasks included:

• Creating REST APIs using the standard net/http library and frameworks like Gin.
• Optimizing multithreaded processes with goroutines and channels for efficient parallelism.
• Working with databases (PostgreSQL, Redis) through drivers and ORM.
• Developing queue systems and event processing using RabbitMQ and Kafka.
• Writing tests and profiling performance to identify bottlenecks.

Example of using goroutines for parallel processing:

func process(items []int) {
    var wg sync.WaitGroup
    for _, item := range items {
        wg.Add(1)
        go func(i int) {
            defer wg.Done()
            // process i
        }(item)
    }
    wg.Wait()
}
