FrontendEngineer.

Across six client products and one platform of my own, the work keeps landing in the same places: complex interfaces where permissions, state and performance carry real weight. The detailed breakdown lives in the CV — this is the shape of it.

Most of my work is interfaces that change shape depending on who's signed in. Here's the pattern as a working specimen — switch the role and watch the navigation, permissions, data and even the audit trail respond. The rules below are illustrative; the technique is what I ship.

Illustrative demo — not client data. In production, every endpoint re-checks the caller's role before responding; the UI reflects permissions, it never grants them.
