Telecom IPDR/CDR Analysis

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.

Key Responsibilities
• Analyze, interpret, and process IPDR (Internet Protocol Detail Records) and CDR (Call Detail Records)
• Understand telecom network concepts related to voice, SMS, data sessions, and internet traffic
• Decode and map IPDR/CDR fields such as:
• MSISDN, IMSI, IMEI
• IP address (IPv4/IPv6), ports, URLs
• Session start/end times, duration, volume
• Cell ID, LAC, tower location
• Perform correlation between IPDR and CDR data for user activity analysis
• Assist in investigations, audits, or analytics use cases involving telecom data
• Work with large datasets and ensure data accuracy and consistency
• Prepare structured outputs, summaries, and insights from raw records

Required Skills
• 2–3 years of hands-on experience working with IPDR and/or CDR data
• Strong understanding of telecom domain concepts
• Ability to independently read, interpret, and explain IPDR/CDR records
• Experience handling large datasets (CSV, TSV, logs, databases)
• Knowledge of data normalization and correlation techniques

Technical Skills (Add-on)
• Python knowledge for:
• Data parsing and transformation
• Automation and scripting
• Basic analytics (pandas, regex, datetime handling)
• Familiarity with SQL databases is a plus
