Stanislav Korolev

Backend Engineer specializing in Go, with a focus on designing and maintaining high-load distributed systems at one of the largest classifieds platforms in the world, serving millions of users daily. My day-to-day stack revolves around PostgreSQL, Apache Kafka, Redis, and Kubernetes-orchestrated microservices, where I tackle challenges around scalability, fault tolerance, and observability at scale. Before transitioning to backend engineering, I spent 4+ years as a mobile developer at major fintech and e-commerce companies, where I shipped products used by millions and developed a strong product mindset. That cross-platform experience gives me a unique perspective on building backend services that truly serve their consumers. I write about high-load system design, distributed architectures, and practical Go patterns
