Key Results
Each investigated issue ended with a reproducible check showing the exact hop where data stopped, so the owning team could act without further back-and-forth.
Technologies Used
Challenges
- Several teams each assuming the fault lay in another system
- Values that were empty at the source but looked lost in the import
- Assets in an old storage bucket that the CDN no longer resolved
- Silent failures with no logs, because log files were being cleared
Solutions
- Bisected each data flow and checked raw files, headers and rows at every boundary
- Replaced guesses such as fallbacks or rate-limit theories with measured read-only checks
- Fixed root causes in reviewed pull requests with tests that fail without the fix
- Reported explicitly what was verified and what was not
Overview
Ongoing support for several e-commerce clients whose data passes through PIM exports, import connectors, object storage, CDNs and third-party sync services. Instead of debating theories, each case was bisected hop by hop with read-only checks on the raw files, HTTP headers and database rows at every boundary. The findings ranged from an export field that was empty before it reached the shop, to a CDN pointing at a bucket that no longer held the assets, to a sync service that silently skipped entries because of a missing join-table row. Fixes were delivered as reviewed pull requests with tests, and every report stated what had not been verified.
