01 About

I'm a first-year Computer Systems Networking & Telecommunications (CNET) student at Holland College, and an international student from Kerala, India. I don't wait for assignments to build things: I've built a full enterprise MSP lab (Active Directory, pfSense, Wazuh SIEM) and I'm moving it to Oracle Cloud with hybrid identity. I learn by building, and everything I list is real and documented on GitHub. This site runs on Cloudflare today and will move to servers I built myself.

Open to summer IT roles in Charlottetown, PEI — MSP, helpdesk, sysadmin, cloud or security.
