About me

I pursue ideas with discipline: structured thinking, direct communication, and follow-through. I value consensus, but act with conviction once a decision is made. Learning never stops — theory and practice alternate until insight becomes impact.

Data AnalysisBusiness AnalysisRelational DatabasesPython (Programming Language)Systems IntegrationUMLData Science
I help organisations turn complex information landscapes into clear, actionable insight — bridging the gap between business strategy and data reality.
With 25+ years of experience across infrastructure, system integration, database engineering and business analysis, I bring both technical depth and strategic perspective to the table. My current focus is on the intersection of business analysis, information architecture and data modelling — with a particular interest in organisations operating in the water and public utility sector.
I work at the level where decisions are made: capturing requirements, mapping information flows, designing conceptual data models and translating organisational complexity into structured solutions. I am equally comfortable facilitating stakeholder workshops and producing formal process models (BPMN, UML, EER).
Currently, I am deepening my expertise in quality assurance and SDLC governance for software development -experience I bring directly to organisations that want to build or improve their digital capabilities with rigour and transparency.
My academic grounding includes MIT xPRO programmes in Machine Learning and AI-driven problem-solving, edX certificates in Python, Data Science and Computational Thinking, and a 2025 micro-credential in Knowledge Graphs (Ghent University) — directly relevant for organisations building semantically connected data ecosystems.
