Professional Summary
Tech Lead / Senior .NET Developer with 19+ years of experience designing and engineering enterprise systems on the .NET platform. The last 6 years at SEFE Securing Energy for Europe GmbH (formerly Gazprom Germania) — a European leader in natural-gas trading, transport and storage: Tech Leader in Saint Petersburg (2019), then Head of Software Development in Berlin (2021–2026), leading international teams of up to 32 across three countries.
Specialisation: modular and microservice architecture, core services, internal developer tooling, legacy modernisation (ASP.NET/WebForms → .NET 6/7/8/10), CI/CD, containerisation, cloud infrastructure (Azure/AWS). Technical principles: Clean Architecture, Domain-Driven Design (DDD), CQRS, SAGA, SOLID, DRY, KISS.
Leadership: built 3 dream teams from scratch, mentored 5+ engineers to senior level, led international teams of up to 32 across three countries. Completed the six-month SEFE Activate Leadership Development Program 2024 (RHR Partners, 2024–2025).
AI engineering: Generative AI, LLM applications, RAG, MCP, AI agents, agentic workflows on Azure AI Foundry, Ollama, n8n, Flowise, LangChain. Led SEFE's AI R&D stream: 24 POC/MVP + 2 production projects.
PhilosophyI don't believe in the false choice between managing and coding. I work in the mode "morning — code and syncs, afternoon — 1:1s and backlog". It's always a compromise: you can't be 4×100% in a single role, it's a tandem between delegation and co-working with professionals. There were three months I barely wrote code because I was building a new team and untangling legacy code. There were weeks I lived in the IDE because the task was critical and needed my code, not explanations or PTO approvals.
AI Augmentation: Daily use of Cursor, Copilot, Claude Code, Ollama, agentic workflow — 4–5× productivity multiplier and offloading of routine work.
