Legacy Data-Provider Transition
The office's investment models had run on a single market-data provider for more than 20 years. When something in the data looked off, I followed up and learned the provider was shutting down, with six weeks' notice. I negotiated an extension to several months and led the work.
- Ran demos with replacement providers and helped choose LSEG, then met with the outgoing provider's remaining staff to capture as much of their methodology as I could before they closed.
- Reverse-engineered the provider's discontinued proprietary calculations and rebuilt them on the new data.
- Converted the Excel model workbooks the investment process runs on, generating stock workbooks from a master template and batch-processing hundreds of files per run, with Power Query consolidation and automation that handles add-ins, link refreshes, calculation timing, and missing values.
- The models kept running through the cutover, and the automation cut prep time about 90% on the affected recurring reports.
