@arhangupta
Cybersecurity-focused assistant system engineer combining Java, OSINT, and VAPT to deliver secure systems.
IndiaWhat I'm looking for
I’m an Assistant System Engineer at Tata Consultancy Services, currently supporting a government sector client project with domain-specific enhancements and maintenance. I work on modifying and optimizing JSP pages, Java classes, PL/SQL package files, and build XML configurations to improve application functionality and performance.
My cybersecurity foundation comes from hands-on work as a Cyber Security Intern at Cybrisk, where I performed OSINT using IPQS, PhoneInfoga, and OSINT Framework. I’ve also run controlled exploitation with Metasploit, extracted evidence using Cellebrite UFED and MagnetAxiom, and performed VAPT on web applications with Burp Suite, Acunetix, and OWASP ZAP.
I enjoy turning security ideas into real tools—like a graphical password authentication system to counter shoulder surfing, AWS IAM policy implementation for secure access control, and an AI-powered threat intelligence model using NLP and logistic regression. I aim to build practical, user-centric defenses, and I’ve demonstrated leadership by leading a team of 4 to publish a detailed NETWORK Vulnerability Assessment Report.
