Aiman Nurzharfan

Computer Networks & Security undergraduate (UTM) — focused on network infrastructure and security. Seeking a networking / infrastructure internship for Sept 2026. CCNA 200-301 in progress (2026).


Featured Projects

  • Network-Design — Two-floor enterprise campus network (7 VLANs, single-area OSPF, VLSM on a /20 block, extended ACLs, NAT/PAT) designed and simulated in Cisco Packet Tracer.
  • NetGuard Sentinel — Autonomous vulnerability triage agent on Microsoft Foundry. Built with Foundry (Phi-4-mini-instruct), Oracle 23ai vector search, Python scanner, React UI, and WCAG 2.1 AA accessibility.
  • SkillForge — Enterprise onboarding runs on guesswork. This multi-agent system turns role readiness into a measured, grounded result using Microsoft Foundry (Phi-4-mini) and Foundry IQ.
  • PintarKod — Full-stack mobile learning app (React Native / Expo, Express, Prisma) with JWT auth and an AI tutor.
  • Packet-Monitor — Full-duplex packet transmission system in digital logic (MUX/DEMUX routing, T flip-flop counters, hardware fault detection).

Thesis (to be published): anomaly-based DDoS intrusion detection on a Ryu SDN controller using multi-window Kalman filtering and Shannon entropy on CIC-DDoS2019 traffic (>95% detection, <5% false positives).


Skills

  • Networking: Cisco IOS, OSPF, VLANs & 802.1Q trunking, NAT/PAT, ACLs, VLSM, TCP/IP
  • Security: Wireshark, Nmap, vulnerability assessment, intrusion detection (IDS), MITRE ATT&CK / NIST CSF (foundational)
  • Programming: Python (network automation), JavaScript (Node.js / React Native), Java, Bash, SQL
  • Certifications: CCNA 200-301 (in progress, 2026), Oracle OCI Foundations, Oracle AI Foundations, TryHackMe (Top 4%)
