Tell us a little about yourself: what did you do at your last job, what were your main tasks, and tell us about a difficult or interesting task you managed to implement recently — what was it, what did you do, and what was the outcome.

At my last job, I was involved in developing high-load microservices in Go for real-time data stream processing. The main tasks included optimizing performance, developing APIs, and integrating with external systems.

One of the challenging tasks was implementing a priority queue system with guaranteed message delivery. The problem was that standard brokers did not meet the requirements for latency and reliability.

I developed a custom mechanism based on Go, using channels and goroutines, which allowed flexible management of priorities and ensured message processing in the correct order. I also implemented metrics and logging for monitoring.

As a result, the system became more stable and efficient, which helped reduce processing delays by 30% and increased stability during peak loads.
