Yuri G.

I build high-performance backend systems in Go that handle thousands of requests per second. I am a Senior Golang Engineer with 10+ years of experience designing and scaling distributed systems for companies like Uber, Yandex, and Wildberries. My expertise: • High-load Go microservices and backend architecture • Distributed systems and event-driven architectures (Kafka, NATS) • PostgreSQL performance optimization (query tuning, indexing, partitioning, sharding) • Kubernetes, Docker, CI/CD, and cloud infrastructure • gRPC, REST APIs, and scalable SaaS platforms • System migrations from monoliths to modern microservice architectures Selected achievements: • Designed and optimized systems handling 8,000–14,000 RPS • Reduced API latency by 20–50% through architecture and database optimizations • Improved database performance by 3–10x through query and indexing optimization • Built event-driven pipelines processing millions of messages per day • Led engineering teams of 4–10 developers and delivered production systems I help companies build backend platforms that are scalable, reliable, and easy to maintain. Whether you need a new Go service, architecture improvements, performance optimization, or help scaling an existing system — I can provide both strong engineering execution and architectural expertise.
