🔐 Cybersecurity Home Lab — Multi-VM Offensive & Defensive Environment

Production-grade isolated penetration testing and threat detection laboratory built from the ground up on VirtualBox — simulating real-world attacker/defender scenarios across a host-only network.
Stack Kali Linux · Metasploitable 2 · Ubuntu (Wazuh SIEM) · Windows 7 · VirtualBox
Network Host-only isolated topology — 4 VMs
Exploits vsftpd 2.3.4 · UnrealIRCd 3.2.8.1 · Samba MS-RPC → full root shell on all
SIEM Wazuh 4.7.5 + Suricata 8.0.5 — live alert monitoring across all nodes
Web Attacks SQL Injection (UNION-based) · Stored & Reflected XSS via DVWA
Post-Exploitation Password hash dumping · John the Ripper offline cracking

Architecture: Kali (attacker) → Metasploitable 2 (primary target) → Ubuntu/Wazuh (detection) → Windows 7 (credential attacks). Documented as a formal penetration test report covering the full kill chain: recon → exploitation → post-exploitation → detection.

📊 AI Stock Risk Report Generator — Claude API Web App

Dark-themed single-page web app that generates AI-powered risk analysis reports for Indian equity and smallcap stocks using the Anthropic Claude API.
Stack HTML · CSS · JavaScript · Anthropic Claude API · Vercel Serverless
AI Model Claude Sonnet via Anthropic API
Target Indian equity market — NSE/BSE smallcap focus
Output Structured JSON risk reports rendered as formatted HTML
Deployment Vercel — live in production
🔑 Password Strength Analyser — Python Security Utility

CLI tool that analyses passwords against entropy, length, character diversity, and common pattern heuristics — built during a remote internship at SkillCraft Technology.
Stack Python · Regex · String analysis · CLI
Coverage Length · Character class diversity · Common pattern detection
Output Colour-coded strength rating with actionable feedback

Implements a weighted scoring model that penalises dictionary-adjacent patterns while rewarding true entropy.

🔒 Caesar Cipher Tool — Cryptographic Python Utility

Python implementation of the classical Caesar cipher with encryption, decryption, and brute-force key-space analysis mode.
Stack Python · Modular arithmetic · CLI
Features Encrypt · Decrypt · Brute-force all 25 shifts
Context SkillCraft Technology Remote Internship
📱 Attendance Calculator — Native Android App (Kotlin)

Android app that calculates minimum attendance requirements and predicts percentage based on classes attended vs held.
Stack Kotlin · Android Studio · XML Layouts
Features Minimum class calculator · Percentage tracker · Skip budget

◈ Experience

Cybersecurity Intern · SkillCraft Technology (Remote) June 2024 – July 2024

  • Engineered a password strength analyser in Python with weighted entropy scoring across multiple character class dimensions
  • Developed a Caesar cipher tool with brute-force key analysis mode
  • Applied modular code structure, CLI design, and security-first output handling
