Kurzvorstellung

If you have a process that needs a program, integration or automation, I can clarify the goal, design the solution and build it in C#/.NET — from hardware and database to backend, UI and deployment, with focus on practical results, not just code.

Über mich

I build custom C#/.NET software for companies that need a practical result, not just code.

I combine 15+ years of software engineering with founder-level responsibility, corporate management experience and a top-tier US MBA — so I look at the business goal, not only at the technical task.

Typical cases:

* connect two systems via API
* move data from Excel, CSV, XML, JSON or SQL into another system
* build an internal tool for a specific process
* connect software with hardware, devices or equipment
* automate manual work that is too slow or error-prone
* repair or improve an existing application
* create reports, imports, exports or reconciliation tools

I work best when the goal is clear, but the exact technical solution is not. I will clarify what is needed, design the solution and build it: database, backend, integrations, UI, deployment and basic production setup.

My background: I built and operated a real B2B platform with hundreds of customers and multi-million turnover, including software, servers, networks, monitoring, support processes and continuous improvements based on customer feedback.

I prefer compact, useful projects with clear responsibility, short communication lines and a visible business result. I can work independently or together with your internal team.

Working language: English or Russian.
German — currently learning; possible for basic communication.
Based in Germany, available for travel worldwide.
Hourly rate: €100/h.
