Data Quality & Web Research Support
Careful source checks, URL verification, and structured research outputs.
I support research and data-entry workflows where accuracy matters: checking source URLs, comparing fields, flagging unclear items, and documenting assumptions. I focus on preventing column shifts, wrong URLs, missing evidence, and unsupported claims before submission.
Role: Web research, data verification, checklist-based review
Tools: Web research, spreadsheets, source tracking, AI-assisted review
This sample is generalized and does not reveal any client list, research target, or marketplace account details.

Google Sheets / Apps Script Automation
Lightweight automation for repetitive spreadsheet tasks.
I build small automations that reduce repetitive spreadsheet work, such as formatting checks, row transfers, simple status updates, and notification-ready outputs. The goal is not overengineering, but making routine operations faster and easier to verify.
Role: Light automation design, spreadsheet logic, testing support
Tools: Google Sheets, Google Apps Script, Python, CSV handling
The visual is a generic automation sample and does not show production data or private scripts.

AI-Assisted Workflow Documentation
Using AI drafts with human review to make repeatable work easier to hand off.
I help turn scattered instructions, messages, and task examples into clear checklists and operating notes. AI tools are useful for first drafts, summaries, and structure, but I review outputs manually and add practical confirmation points before anything is used in real work.
Role: Workflow documentation, checklist design, AI output review
Tools: ChatGPT, Claude, Google Docs, Notion-style documentation, spreadsheets
This is an anonymized work sample. It does not include client instructions or private workflow details.

Spreadsheet Operations Cleanup
Turning messy operational sheets into clearer, reviewable workflows.
I design practical spreadsheet structures for small teams that need cleaner data, fewer manual checks, and better visibility. A typical cleanup includes separating intake data, master data, status tracking, review notes, and final output tabs so the workflow is easier to maintain.
Role: Spreadsheet structure, data cleanup, review flow design
Tools: Google Sheets, Microsoft Excel, data validation, formulas, process notes
This is a generalized sample based on the type of spreadsheet operations support I provide. No client data is shown.
