👋 Hi, I'm Vladimir Gavrilenko --- Backend Engineer (Go)

I build reliable backend systems with Go, focusing on gRPC, microservices, performance, and automation.
My work spans infrastructure tooling, real-time services, Telegram bots, CI/CD pipelines, and integrations with external APIs (OpenAI, crypto exchanges).

I'm open to backend roles (Go), remote or hybrid.

🚀 Core Tech Stack

Backend: Go (Golang), gRPC, REST, WebSockets
Databases: PostgreSQL, SQLite, MongoDB
Architecture: microservices, clean architecture, modular & layered design
DevOps: Docker, Docker Compose, GitHub Actions, CI/CD, pprof profiling
Automation: infrastructure deployment tools, Telegram bots, external API integrations
Testing: unit tests, integration tests, scenario testing
