Editorial Process
Practical, reviewed notes
Articles are written from hands-on engineering work, personal experiments, production lessons, and technical research. I prioritize concrete tradeoffs, implementation details, and source links when a post depends on external behavior.
AI Disclosure
AI-assisted, human-owned
I may use AI tools to outline, review, edit, or pressure-test ideas. Final article structure, technical judgment, code review, and publishing decisions remain mine.
Safety Scope
Defensive engineering only
Security content is framed for prevention, review, and safer system design. Posts avoid credential exposure, unauthorized access, and exploit instructions.
