About me
Data engineer and web scraping specialist with an applied mathematics background.

Work experience

NETworks

AI Tools Development Expert

NETworks • Freelance

Feb 2025 - Present • 1 yr 8 mos

Deployed a photo-tagging system from scratch, with the full MLOps pipeline and stack. Data analysis and solution-finding, process-first: I judge where AI genuinely helps and where the process itself needs fixing, and deploy AI only where it pays off.

WebDataWatch

Freelance Data Engineer and Web Scraping Specialist

WebDataWatch • Self-employed

Oct 2017 - Present • 9 yrs

Web scraping and data projects for clients worldwide in Python, R and VBA. I run WebDataWatch (webdatawatch.com), my own data-collection service with 40+ sources, sold as datasets on the website, through resellers and as custom orders. Earlier client work on Upwork included an R API service on OpenCPU and document-structuring tools. Data-engineering work for the FURBS Foundation.

DIABLO_CHAIRS

Machine Learning Specialist

DIABLO CHAIRS • Freelance

Apr 2024 - Feb 2025 • 10 mos

Hired to forecast sales; the analysis showed the ordering process itself was the bottleneck, so the deliverable became the process. Built end-to-end order tracking: suppliers' production in China, deliveries, stock levels and a forecast of when goods run out, critical with 3-6 month lead times. Built a tool that organized the ordering process from scratch. Stack: Python, PostgreSQL, Power BI, n8n, Docker, Git, Azure DevOps CI/CD.
