Ur Rehman
Bridging enterprise-grade e-commerce engineering, mathematical supply chain logistics, and offensive/defensive cybersecurity research.
whoami
Two cores, one operator. One half engineers commerce systems at scale; the other half breaks and hardens networks.
Enterprise E-Commerce Systems Engineer
I architect mathematical logistics pipelines, Cash Conversion Cycle (CCC) optimizations, quantitative niche segmentation (HHI), and programmatic ad infrastructure through AMC/DSP clean rooms.
Cybersecurity Researcher
I specialize in penetration testing, log correlation, Splunk SIEM deployments, and Python-driven security automation, building hardened topologies with pfSense, Snort/Suricata and FortiGate.
Competencies
Live view of the stack — capability levels and a running telemetry feed.
Product Research & Development
Quantitative niche fragmentation, Herfindahl-Hirschman Index (HHI) analysis, and semantic FMEA review mining to engineer defect-free BOMs.
Strategic Supply Chain
Statistical Reorder Point (ROP) inventory modeling, Cash Conversion Cycle compression, and multi-channel ERP routing via Sellercloud.
Mathematical Logistics & PPC
API-driven dayparting algorithms, placement multipliers, and Amazon Marketing Cloud clean-room SQL attribution modeling.
Offensive & Defensive Security
Vulnerability assessment, reflected XSS web auditing, network segmentation, and FortiGate firewall rule enforcement.
Python Security Automation
Custom socket tooling, AES-256-GCM encrypted communication channels, and automated vulnerability scanner workflows.
Enterprise SIEM Architecture
Centralized Splunk log ingestion, Snort/Suricata signature tuning, and pfSense firewall anomaly correlation.
Experience
Where both cores have been deployed.
Insync Products Ltd
Architecting algorithmic supply chain models, quantitative ROP calculations, and programmatic advertising frameworks across global channels.
Care MSO
Deploying pfSense VLAN segmentation, Snort/Suricata IDS/IPS nodes, and Splunk SIEM log correlation. Automating vulnerability scans with Python.
Edsavvy Solutions
Optimized warehouse logistics, scaled marketplace presence by 40%, and implemented automated EDI routing and ERP ledger synchronization.
