I have millions of historical voice recordings (VOX) and their metadata (CDRs), but the main unique ID that links them is broken and the audit log is gone for the older records.
I need an expert to look at our raw data files (CSVs) and tell me the absolute best way forward.
You'll need to look beyond the obvious fields, find a defensible, mathematical way to link the data, and give me a clear plan to handle the ambiguous calls (collisions). We'll share our current ideas, and we need your expertise to turn this data crisis into a clean, compliant migration.
So far I am linking on start time and duration. I will need to write code to group the data for a single call.
Please quote hourly or fixed cost. I will send out spec asap.
