Experience
Cybersecurity Intern at Thiranex IT Solutions (2026 – Present)
- Reduced simulated attack surface by scanning 100+ open ports and services across target hosts by building a Python + Nmap based vulnerability scanner that automated host discovery and service enumeration.
- Improved password policy compliance by enforcing entropy-based strength rules (length, character diversity, pattern detection) by developing a password strength analyzer that flagged weak credentials before storage.
- Achieved 87% accuracy in phishing email classification across a labeled dataset of 2,000+ samples by engineering NLP-based features (URL patterns, sender spoofing, urgency cues) and training a Random Forest model.
- Eliminated SQL injection and credential stuffing vectors in a login workflow by implementing SHA-256 password hashing, prepared statements, and session-based access control using Java and MySQL.
