Tell about your last place of work: what you did, stack, difficult tasks?

At my last job, I was involved in developing microservices in Go for processing large streams of data in real-time. The tech stack included Go, gRPC for inter-service communication, PostgreSQL and Redis for data storage, as well as Docker and Kubernetes for deployment.

Main tasks:

• Optimizing service performance, reducing processing delays.
• Implementing a reliable queue system using Kafka.
• Refactoring legacy code to improve readability and maintainability.

Complex tasks included:

• Solving issues related to concurrent data access and race conditions.
• Ensuring fault tolerance and automatic recovery of services.
• Implementing monitoring and logging for quick detection and resolution of problems.
