About Me

I’m a tech enthusiast who loves building systems and making sure they’re secure. Whether it’s designing a network from the ground up or setting up a cybersecurity lab to simulate real-world threats, I thrive on creating solutions that are both functional and protected. I’ve spent countless hours tinkering with tools like Kali Linux, Security Onion, and Splunk to detect vulnerabilities, monitor threats, and respond to incidents. I also enjoy diving into cloud platforms like Azure to deploy secure, scalable applications. For me, it’s not just about making things work—it’s about making sure they’re resilient, safe, and ready to handle whatever comes their way. I’m always excited to learn, experiment, and find new ways to keep systems secure while driving innovation.
