    For over a decade, I’ve been passionate about linking data. My creative vision for integrating Large Language Models and Knowledge Graphs within large organisations has gained widespread attention, particularly through my weekly LinkedIn posts, earning me the reputation of ‘The Knowledge Graph Guy.’
    My journey into AI and Knowledge Graphs began as a secret side project, working from a computer hidden under my desk. What started as a personal passion quickly evolved into an area of deep expertise. Over the past decade, I’ve successfully delivered several mission-critical Knowledge Graphs into production for Tier 1 investment banks, helping these institutions better organise and leverage their data.
    Today, as the founder of The Knowledge Graph Guys, I am dedicated to helping organisations harness the power of their data. Our consultancy develops cutting-edge Knowledge Graphs that fuel innovation and growth in the rapidly evolving Age of AI.

    I became absolutely passionate about knowledge graphs and semantic modelling during my PhD in Aerospace Engineering, where one of my goals was to align different industry stakeholders in a European project on the definition of certain novel technologies. I have since then worked to apply semantic web technologies in Natural Language Processing applications and data integration projects. I am very excited to have joined the Knowledge Graph Guys, where together we can push the boundaries of these technologies, and integrate the continuous world of LLMs and machine learning, with the discrete world of knowledge graphs and linked data. I love that we take on this challenge and take it from academia and blog posts into real-world scenarios in production environments.s

    I am a knowledge graph engineer driven by a passion for knowledge graphs and the vision of the semantic web. Having a background in supply chain management, I see graphs as powerful tools for breaking data silos and enabling semantic interoperability. I am particularly inspired by the potential of neuro-symbolic AI and enjoy exploring how these technologies can be implemented in innovative and effective ways that realise value for our clients and push the boundaries of AI

    I bring 12 years of programming experience and have recently completed my studies, where I focused on Artificial Intelligence and Reverse Engineering. I believe AI has the power to reshape the world and the way we interact with data. That vision is what excites me about joining The Knowledge Graph Guys, where I can contribute to the mission of bringing the semantic web to life.

    With a background in qualitative research and coaching, my passion has always been people and meaningful connection. As People and Culture lead, I carefully select people whose character reflects our culture and foster strong relationships within the team. At The Knowledge Graph Guys, we put people at the heart of our business and are driven by curiosity to see what we can achieve when we truly prioritise them. This focus is rare in tech companies and makes our team not only innovative, but also more rewarding to work with
