Narrative:

On the arrival into ZZZ; ATC commanded a descent; which I selected level change; frequency change and then cleared for the RNAV xxr approach. After reprogramming the approach from the left to right and briefing; I failed to select VNAV before busting the 7;000 feet restriction at zzzzz. We immediately disconnected the autopilot and returned to 7;000 feet. The remainder of the approach was uneventful.prioritizing the sequence of events. Basic piloting. Having flown little in the last 90 days; my proficiency level is not as it normally is. Be aware of this and that I am in the yellow. Work harder at staying in the green.
