About
Dhanush B S
Diploma student in CSE · Cybersecurity & Networking · Bengaluru, IN
Dhanush B S, a Diploma Computer Science & Engineering student in Bangalore, currently in Semester 5 and focusing on Cybersecurity.
His strongest interests are hardware troubleshooting and deep system understanding, paired with cybersecurity and networking. Long-term goal is a Network Engineering career, building toward CCNA/Cisco certification and a dedicated home lab with a SOC/security-analysis environment. Outside of coursework, I build small Microcontrollers & Electronics and Home IoT Projects for fun, they're a natural extension of the home lab work.
