Top SchoolRogers John is a seasoned engineering and product leader with 12 years of experience building cloud-native, enterprise-grade AI systems and a PhD in computer science from the University of Wisconsin–Madison. As co-founder and CTO of DataChat, he architected a scalable microservice platform and a multi-agent generative AI framework that helped the company earn Gartner recognition in 2024 and close Fortune 100 lighthouse accounts. He combines deep research credentials with hands-on delivery—shipping production-ready GenAI products, instituting agile release trains, and reducing release cadence from monthly to weekly. His work on HITL feedback, RAG/vector search grounding, and LLM-as-a-Judge self-correction cut failure rates over 60% and halved evaluation cycles. Now directing Agentic AI engineering and product at Mews, he continues to bridge R&D and go-to-market strategy while scaling global teams and integrations across AWS, GCP, and Snowflake. An inventor with multiple issued patents and frequent industry talks, he brings a rare mix of academic rigor, product intuition, and operational execution.
