Java Full Stack Developer who built a MISP-based threat intelligence platform with authentication and automated malicious URL detection.

What I'm looking for

I’m looking for opportunities to take on new challenges, grow as a versatile full-stack engineer, and apply my skills to deliver working solutions.

I built a MISP-based full-stack web application to centralize threat intelligence data, with user authentication and integrations to threat-intelligence APIs for malicious URL detection. I also designed its MySQL database and handled inconsistent API responses and provider failures.

At BIST Technologies Pvt. Ltd., I built Java applications using object-oriented programming and the Collections Framework, connected programs to MySQL with JDBC, and developed Java Swing applications. As a Cybersecurity Intern at Excel R Technologies, I analyzed system and network vulnerabilities and supported threat assessment and incident response workflows.
