Quentin Reul

Quentin Reul

Quentin Reul, Ph.D., is the Director of AI Strategy and Solutions at expert.ai, bringing over 25 years of experience navigating the evolution of artificial intelligence from early symbolic systems to today’s neural era. Originally from Belgium, he earned his doctorate at the University of Aberdeen, where his research focused on ontologies and semantic interoperability. Dr. Reul is a leading advocate for a "problem-first" approach to innovation, frequently challenging organizations to "fall in love with the problem, not the solution". By utilizing the Jobs to be Done (JTBD) framework, he helps businesses anchor technology in measurable customer pain points, ensuring that AI acts as a genuine accelerator rather than a "shiny new object".

As a pioneer in neuro-symbolic AI, Dr. Reul champions a hybrid architecture that integrates the creative power of Large Language Models with the deterministic precision of Knowledge Graphs to alleviate hallucinations and ground AI in reality. He is a prominent voice in Responsible AI, serving as an active contributor to the IEEE working group on AI ethics oversight to define global standards for transparency and fairness. His strategic "Cost to be Wrong" framework provides a pragmatic lens for assessing AI risk in zero-tolerance industries like healthcare and law, emphasizing the necessity of "expert-in-the-loop" supervision. Through his Lean AI Innovation methodology, he empowers enterprises to transform their proprietary data into a sustainable competitive advantage while navigating the complex "pilot-to-production chasm".

Vishal Alhat

Vishal Alhat

No pitch decks. No service demos. Just real solutions to real developer problems.

That's the promise Vishal Alhat brings to every stage. A former AWS Hero turned Developer Advocate at AWS, he has spent over 11 years as a practitioner — architecting cloud-native systems, automating infrastructure, and learning (sometimes the hard way) what it actually takes to ship resilient applications at scale.

Vishal specializes in AI/ML, Security, DevOps and FinOps. He speaks at major global conferences on zero-trust architectures, MLOps pipelines, and responsible GenAI development — always from a developer's perspective, focused on solving pain points with open standards and battle-tested patterns, not promoting platforms.

His community impact speaks for itself: 5,000+ developers mentored, the Community Builder of the Year award, and the HashiCorp Ambassador recognition — credentials earned by the ecosystem, not by a corporation. Through technical writing, open-source contributions, hands-on workshops, and speaking engagements, Vishal makes complex cloud concepts accessible to developers at all skill levels.

Whether he's helping a team adopt zero-trust without the complexity or demystifying secure AI pipelines, his mission is simple: help developers build boldly, ship confidently, and sleep peacefully.

Vishal is available for global speaking engagements and does not require travel or accommodation assistance.
