About me

Senior product engineer and pure agent-orchestrator. I ship production apps end-to-end by designing architecture, contracts, acceptance tests, and running agent teams through my own Fixer MCP control plane. Strongest lanes: Go/Serverpod backends, Flutter/iOS delivery, AI/LLM integrations, automation systems, Postgres, APIs, and production rescue. Background: 7+ years in software, research work at Sberbank, Ecole 42/C, and several launched products including Soulwi, Civique, a VPN product, an AI real-estate product, and a philology platform. I am best for founders who need a working MVP or broken product turned into a stable, shipped system quickly.
