// NET-DEPLOY-01 · HIGH PERFORMANCE

Deep Packet Inspection (DPI) Firewall Engine

Engineered a low-level C++ network security firewall capable of inspecting raw Layer-7 packet payloads in real-time, matching signature-based attack vectors, and enforcing rule-based traffic drops.

  • Extracts Ethernet, IPv4, TCP/UDP headers using custom binary decoders
  • Applies regex signature matching for SQL injection, XSS, and payload anomalies
  • Maintains connection state tables and packet drop telemetry metrics

// NET-DEPLOY-02 · REAL-TIME TELEMETRY

Distributed Network Intrusion Detection System (NIDS)

Built a distributed intrusion detection pipeline leveraging Python and Scapy to monitor network interfaces, identify ARP poisoning attacks, detect SYN flood anomalies, and stream instant alerts to a React UI via Socket.io.

  • Automated ARP cache poison detection and broadcast anomaly triggers
  • SYN/FIN/NULL stealth port scan identification algorithms
  • Sub-50ms alert streaming with live packet breakdown and severity grading

// NET-DEPLOY-03 · HACKATHON BUILD

Real-Time Full-Stack Network Telemetry Platform

Architected a full-stack web application in 24 hours at the GEHU Tech Geeks Hackathon featuring RESTful endpoints, live host status polling, MongoDB persistence, and secure token-based authentication.

  • Built scalable REST API routes with Express and asynchronous Node.js workers
  • Implemented JWT-based authentication and role-based access control
  • Responsive React frontend rendering dynamic status charts and event feeds
