ABOUT

Who I Am & What I Build

I am Sultanus Salehin, a CSE graduate candidate targeting Cybersecurity Engineer and Network Security Engineer roles. My CV combines a 4-month Cyber Security Internship at Goinnovior IT LTD, production website administration, secure deployment work, and security-focused research.

I work across network security, vulnerability assessment, secure communication, web security, IoT security, REST APIs, backend integrations, Python scripting, technical documentation, access control, secure configuration, and risk-aware reporting.

Through Erasmus+ KA-171 International Credit Mobility at Yildiz Technical University (YTU), I gained international academic and team collaboration exposure across software engineering, AI, computer organization, and big data processing and analytics.

My earlier hands-on work includes microcontroller-based robotics, Pixhawk flight-control experiments, real-time face and emotion recognition, and DIU training in precision mapping with drones and aerial robotics. These builds established the embedded-autonomy foundation behind my current secure IoT and AI research.
