COO • Operations • AI

I build operations
that scale. Then I automate them.

15+ years leading supply chain, procurement, and operations across Europe. Now building the governance layer for enterprise AI agents.

Liem Chatjellis

Operations leader.
AI builder. Founder.

I have spent my career building, scaling, and transforming operational functions from the ground up. From launching supply chains in new markets to managing over €100M in cumulative procurement and operational budgets, I operate at the intersection of strategic leadership and hands-on execution.

Today, I combine deep operational expertise with a forward-looking focus on AI and automation. I am building WorkingAgents, a governance and orchestration layer for AI agents and LLM systems, because I believe the next frontier of operational excellence is not just process improvement but intelligent system design.

ERP & Systems Implementation

ERP platform selection, design, and deployment. EDI integration. Process digitalization. Turning manual workflows into automated, data-driven operations.

AI & Automation Strategy

AI readiness assessment, agent-based automation design, and governance frameworks. Practical AI integration grounded in operational reality, not hype.
