What was the last thing you worked on?.

In my last project, I worked on developing a high-load microservice in Go that processed streaming data in real-time. The main tasks included optimizing performance, implementing effective error handling, and ensuring scalability.

For example, I implemented a goroutine pool for parallel processing of messages from a queue, which increased the service throughput by 3 times without increasing memory consumption.

func worker(id int, jobs <-chan Job, results chan<- Result) {
    for job := range jobs {
        // process job
        results <- process(job)
    }
}

I also worked on integrating with external APIs and setting up monitoring with Prometheus and Grafana.
