Structured technical documentation from my TryHackMe learning progress. Each room I complete gets a writeup covering the methodology, commands, concepts, and tools I used — organized by learning path and module for reference and review.
| Path | Status |
|---|---|
| Pre-Security | Completed |
| Cyber Security 101 | Completed (14/14 modules) |
| Jr Penetration Tester | In progress (27% — 4/15 modules) |
SEC0 Professional Certification earned. Foundational knowledge across networking, operating systems, web technologies, and security operations.
PreSecurity/ — 7 modules, 31 rooms with room-level writeups, concept deep-dives, command references, tool guides, cheat sheets, diagrams, and interview questions.
