About

Agency seniority, in the work

Three years at a mid-sized digital agency (Matrix Group International) as a Developer (2022-present). Second-most-senior of four WordPress developers: code review, mentoring, onboarding, estimates, and direct client communication. I can own a workstream, not just tickets.
