Team leadership, Team building, Problem solving

• Developed custom Python tools for information gathering and automated security testing—capable of extracting OS info, network configs, firewall status, and performing advanced port scans.
• Utilized image steganography on Parrot OS to embed Python payloads within image files, enabling stealthy testing of detection mechanisms and validating remote code execution scenarios using Metasploit in a virtual lab setup.
• Researched business logic vulnerabilities in real-world applications; published technical walkthroughs and exploitation strategies on Medium, helping security learners and professionals understand edge-case flaws.
• Simulated phishing & email-based attack scenarios—analyzed mail headers, attachments, and link redirection chains using tools like Wireshark, SentinelOne, and email sandboxing to identify spoofing and payload delivery methods.
