Go (Golang) Development

Microservices, distributed systems and gRPC in Go (Golang): Designing compact, scalable and fault-tolerant backend systems with native concurrency support via goroutines and channels. Development of lightweight REST APIs (Gin, Fiber, Chi) and inter-service communication via gRPC / Protocol Buffers. Building message brokers (Kafka, RabbitMQ, NATS), Redis-based caching and integration with relational databases (GORM, SQLx, pgx). Packaging services into Docker microcontainers starting from 15 MB for fast horizontal scaling in Kubernetes.
