I hold a substantial volume of raw IPDR and CDR files and need a developer who can dive straight into the records, understand every field, and turn the data into clear, actionable insight. The work goes well beyond simple parsing—I want full-scale interpretation and processing so I can investigate network activity and produce solid reports.
