AI Solution Architect & Engineer · Senior Full-Stack Developer

I build production-ready AI-enabled software at the intersection of full-stack engineering, web platforms, business processes, and practical AI integration.

My focus is on turning AI capabilities into systems that work beyond demos: LLM-based workflows, RAG architectures, agent-based systems, MCP integrations, AI-assisted software delivery, workflow automation, and GDPR-conscious AI solutions.

At the same time, I bring more than 15 years of experience delivering complex web platforms and custom software end to end — from discovery and architecture through implementation, project management, quality assurance, deployment, operations, and continuous improvement.

Current focus

  • AI integration into existing products and business processes
  • RAG architectures and LLM-based workflows
  • AI agents and agent-based systems
  • Model Context Protocol (MCP)
  • Human-in-the-loop workflows
  • AI-assisted and agentic software engineering
  • Workflow and process automation
  • GDPR-conscious and data-sovereign AI architectures
  • Technical discovery and solution design
  • Rapid proof-of-concepts and domain onboarding itty.
