Tell about your latest technical experience, what tasks you did, what was more engaging?

In my latest project in Go, I was involved in developing a high-load microservice for processing streaming data. The main tasks included:

• Implementing a REST API using the standard net/http library and the Gin framework.
• Optimizing database interactions with PostgreSQL through the pgx package.
• Implementing caching with Redis to reduce latency.
• Writing unit and integration tests to ensure stability.

I was most interested in optimizing performance and working with concurrency in Go — using goroutines and channels for efficient handling of parallel requests. This significantly increased the service's throughput and reduced response times.
