Not a list assembled for this page. These are the rules I actually hold myself to, and every project below was built under them.
- 01Debugging-first problem solver
- 02End-to-end ownership, business context to production
- 03Layered quality gates
- 04Commitment · Communication · Respect

Two employers, one continuous climb
The ladder, not the job list. Each rung is a title actually held; the projects under it are clickable.
Formal grounding, still going
The M.Sc. is the research counterpart to the security work, not a side quest.
