What dedicated means

The same person. Your standards. Clear ownership.

One consistent point of ownership

You work with the same person, not a rotating queue. They learn your priorities and become accountable for the agreed work.

Embedded in your workflow

Your team member works with your tools, templates, naming conventions, checklists, and review points.

Capacity that grows deliberately

Begin with a defined scope, then expand hours and responsibilities as quality and demand justify it.
