Ruslan H.

I build and ship production software faster by pairing 10+ years of .NET/web/desktop engineering with agentic workflows built on Claude AI and Claude Code, without trading away architecture, tests, or maintainability.

Whether you need an MVP from scratch, a legacy system modernized, or AI agents integrated into your product, I take ownership end to end.

🔹 What I do
• Agentic development: Claude Code with subagents, custom commands, hooks, and project-level CLAUDE.md conventions, so AI output follows your architecture and standards.
• AI features & agents in your product: Claude API (tool use, structured outputs), MCP servers, RAG, and human-in-the-loop workflows.
• Legacy modernization: AI-assisted migration from .NET Framework/WCF/WinForms to modern .NET, with characterization tests first.
• System architecture & full-stack: scalable backends, APIs, web and high-performance desktop apps.
• Critical systems: real-time, industrial, and computer-vision software where reliability is non-negotiable.

🔹 How I work with AI (and keep quality high)
• Spec first, then agent: clear requirements and acceptance tests before code generation.
• Every AI-generated change is reviewed by me; tests and CI gates are the contract.
• Automated PR review and test generation in GitHub Actions.
• Security-conscious: no secrets in prompts, scoped permissions, careful handling of your private code.
