Clean data,
clear decisions.

I'm Eya. For the last ten years I've untangled the spreadsheets teams had quietly given up on. Send me the mess and I'll send back numbers you can actually stand behind.

The DataFlow Engine
The same careful process, every time.
Every file I take on goes through the same steps, in the same order. That's why the result holds up whether it's fifty rows or half a million.
The DataFlow Engine — raw, messy spreadsheet data flowing through a cleaning and analysis pipeline and emerging as a clean, verified report

Data Transformation
Messy in.
Trusted out.

I show my work. Every change gets logged with a reason, so you can see exactly what was wrong and what I did about it. Nothing disappears without a note.
