What I do in plain English
Clean & standardize large datasets
– De-duplicate records, normalize phones to E.164, trim ZIP5, align company names
– Tools: Python (pandas, RapidFuzz), SQL, Excel / Power Query
– Typical output: import-ready CSV/TXT + change-log and QA summary
Translate government publications into action plans
– CMS PCUGs, Federal Register notices, grant NOFOs, FAR/DFARS updates
– Extract dates, dollar values, compliance triggers; map to decision tree and ROI model
– Deliverables: 2-page brief or 8-slide deck + Excel impact matrix
Automate repeat processes
– Build re-usable scripts/macros so the next data drop or reg update takes minutes, not days
