Data Operations Specialist | Web Developer | Computer Engineer
I specialize in data operations and workflow automation. I take messy spreadsheets and turn them into organized, usable systems. My goal is to keep business data accurate and easy to work with.
DATA SERVICES
Data Entry and Database Management. High-volume data entry with strict quality checks. I have handled confidential records, tax paperwork, and large datasets.
Spreadsheet Engineering. Advanced work in Excel and Google Sheets — VLOOKUP, INDEX-MATCH, pivot tables, conditional formatting, data validation, Power Query, and VBA macros. I build templates that cut hours off manual tasks.
Data Cleaning and Validation. I find duplicates, fix inconsistencies, and standardize formats. For big jobs I use Python with Pandas and NumPy.
Data Analytics and Visualization. I turn raw numbers into clear reports and dashboards — revenue breakdowns, sales trends, performance metrics.
Workflow Automation. I use Google Apps Script, Python, and Excel macros to automate repetitive tasks like data imports, report generation, and file organization.
E-commerce Data Management. Shopify product listings, inventory updates, and catalog organization. I keep product info consistent across all sales channels.
WHAT I'VE BUILT

I combine hands-on data experience with the technical skills to build better systems. Before freelancing as a developer, I managed data for several clients — tax records, Shopify catalogs, customer databases — always with strict accuracy. That background gives me a practical understanding of data work from both angles: the operational side and the technical side.
I am looking for roles in data operations, spreadsheet management, workflow automation, or technical coordination where I can keep things running smoothly.
