Description

I am a Senior Data Analyst and Engineer with 15+ years of experience in high-stakes sectors like Banking and Public Administration. Currently, I specialise in the human-centric validation and benchmarking of AI systems.

I help organisations ensure that their data-driven outputs—whether from traditional BI tools or modern AI models—are accurate, logical, and technically sound. My approach combines deep analytical experience with a rigorous engineering mindset to audit and improve the reliability of technical information.

What I offer:

Expert AI Evaluation: I provide the 'human-in-the-loop' necessary to ensure AI outputs are safe, accurate, and technically sound, especially in STEM fields.
Analytical Rigor: Using my experience in BI, I analyse data trends and transform them into strategic dashboards.
Technical Versatility: A strong foundation in SQL, Python, and R, combined with a deep understanding of infrastructure (AWS) and project management.
