About

Solo founder based in Ukraine, currently in Spain. I build ReadyCSV, a browser-only preflight and repair tool for HubSpot Contacts CSV imports, and SkuSum, which turns Amazon settlement files into per-SKU profit and a balanced QuickBooks or Xero journal. Both run entirely client side: no upload, no account, no AI calls. I'm here to get feedback from people who actually deal with messy client data for a living. Always up for a straight critique.

What actually breaks HubSpot contact imports (notes from building a preflight checker)

I spent the last few months encoding HubSpot's contact import rules into a checker, and the list of things that actually go wrong turned out shorter and dumber than I expected. Sharing the categories in case it saves someone a re-import.

What keeps showing up:

1. Missing identity field. No email and no record ID means nothing to dedupe against.

2. Mixed date formats inside a single column. One column with 2026/03/11 sitting next to 11-03-2026.
