Need help cleaning messy spreadsheets, automating manual data tasks, or making sense of company data from ERP, CRM, or Restaurant365 (R365)? I build lightweight, reliable tools using Python, SQL, and Excel that help teams save time and avoid costly errors. I specialize in: Automating spreadsheet work (e.g. BOM cleanups, cost comparisons, data merges) Building internal tools for engineering, product data, and operations Custom SQL queries & dashboards for visibility into JDE, SAP, or other systems Extracting, validating, and loading data between systems or formats (Excel ↔ SQL) At my day job, I work on the PDM team at a global manufacturing company, where I’ve built: A tool that validates BOM part compatibility using rule logic Python scripts that flag cost mismatches and missing ERP data Internal web apps (Flask + SQL Server) for engineers to manage configurations Setting up or optimizing Restaurant365 (R365): recipes, inventory, menu items, item location links, and transfers I'm easy to work with, fast to respond, and happy to take on short-term, part-time, or urgent projects. Let’s fix your data headaches — message me and I’ll help you get unstuck.
