Experience

Cybersecurity Intern · Prodigy InfoTech (Remote)

Network Defense & Penetration Testing · June 2024 — July 2024

  • Analysed TCP, UDP, HTTP and DNS traffic with Wireshark and custom scripts to flag anomalies in hands-on lab exercises.
  • Practised reconnaissance and vulnerability assessment for penetration testing, and applied symmetric and asymmetric cryptography on practical targets.

Projects

Eigenguard — Hybrid Intrusion Detection System

Python, Scikit-learn, CICIDS2017 · GitHub

  • Designed a hybrid IDS combining signature-based rules with machine learning anomaly detection so both known signatures and novel attacks are caught.
  • Benchmarked classifiers on CICIDS2017 traffic, with a React dashboard, an ML detection pipeline and an SSH honeypot that captures attacker credentials.
  • Key finding: leave-one-tool-out recall of 0.40 against 0.999 random-split F1, showing the model had learned path-probing rather than injection payloads.

Network Packet Analyzer & Security Assessment Tool

Python, Scapy, Tkinter, Threading · GitHub

  • Built a multithreaded capture pipeline that decouples the Scapy sniffer from the Tkinter GUI through a bounded queue, removing peak-load freezes.
  • Boosted throughput 7.4× (1,107 → 8,200 PPS) by removing redundant serialization, cutting p99 latency to 442 μs.
  • Engineered 4 real-time alert rules — SYN flood, port scan, credential leak and oversized flows — and fixed a 0.500 precision regression.
  • Added session export to PCAP, CSV and JSON with a lightweight memory footprint.

Phishing Simulation & Awareness Portal

PostgreSQL, React, REST APIs · Ongoing · GitHub

  • Building a full-stack application that launches simulated phishing campaigns and measures employee click and report behaviour.
  • Implemented campaign management, user tracking and training workflows with a React dashboard, PostgreSQL database and REST APIs.

Image Encryption System

Hybrid Encryption, CLI · GitHub

  • Developed a CLI tool using hybrid encryption: fast AES for image and media files, RSA for secure key exchange.
  • Automated key pair generation and one-command encrypt/decrypt workflows, keeping confidentiality strong and key handling simple.

Mama’s Cafe — Production Restaurant Website

Responsive Frontend, Deployment · mamascafe.cafe

  • Designed, deployed and maintain a responsive website for a real restaurant, owning delivery from first sketch to production.
