About

I work at the intersection of operations, data and process improvement, using analytical thinking to solve practical business problems. My background is in stock control, logistics and QA/QC, where I analyse operational data and build tools that reduce manual work, improve data visibility and support better decision-making. Most of my projects combine SQL, Excel, Power Query, VBA and, increasingly, Python and Power BI. Rather than producing reports for their own sake, I prefer understanding how a process works, identifying where data can remove friction, and building solutions that people actually use. My projects include inventory movement analysis, BOM exploration, delivery planning, QA reporting and warehouse investigation tools. Alongside hands-on commercial experience, I am expanding my skills through a Data Science programme, applying new techniques directly to real operational datasets and continually refining my approach. I am interested in opportunities within Data Analysis, Operational Analytics, Business Intelligence and Supply Chain Analytics, where technical skills and business understanding are equally important.
