• P2P and Networks: libp2p (Kademlia DHT, NAT traversal, mDNS), TCP, gRPC
• Databases: SQL, SQLite, PostgresSQL, Redis
• Tools: Docker, CI/CD, GoReleaser, Git
• Additional: layout (HTML/CSS/JS) according to Figma mockups with UI kit, Python, integration of AI assistant APIs

💡 What I'm looking for Remote work (full/part-time). I adhere to the principle "You provide the goal and payment - I provide implementation and documentation". Flexible schedule, adapting to the time zone.

🔄 Working with existing code: Ready to dive into any project, understand legacy code, perform refactoring, or build projects from scratch. Have experience in team development and code review.
