Stefan Junk
AI Transformation Lead & Cloud Architect
Profile
I build AI agents and agentic workflows that drive large-scale cloud migration and digital transformation. At Accenture, I design automation systems that orchestrate migration programs, assess and eliminate vendor lock-in, and transition organizations to open source architectures. My background spans AI startup founding, enterprise cloud transformation, and academic research—giving me a holistic view that bridges business strategy, hands-on engineering, and applied AI.
Focus
- AI Agent Orchestration
- Vendor Lock-in Removal
- Open Source Migration
- GenAI
