Want security-aware web work?

I build responsive sites with safer defaults — and I’m open to internships and collaboration.

Lab Notes

What the labs actually drilled.

The concepts the TryHackMe paths above hammered in, and the habit each one left behind — not step-by-step solutions.

Network enumeration

Recon

Mapping open services before touching anything. The habit that carried over: know what a system exposes before assuming what it does.

NmapService detectionBanner grabbing

Web request tampering

Web

Intercepting and replaying requests with modified values. This is why I now validate on the server even when the browser already checks.

Burp SuiteHTTPInput validation

Linux privilege escalation

Linux

Misconfigured permissions and forgotten defaults doing more damage than any exploit. Made me read defaults instead of accepting them.

LinuxPermissionsEnumeration

Traffic analysis

Analyst

Reading captures to reconstruct what happened. Useful far beyond security — it is also how I debug a request that silently fails.
