Narrative:

While climbing out of ZZZ; initially we were assigned to climb and level at 4;000 feet which changed to 7;000 feet. I engaged the autopilot at 5;000 feet and maintained 250 kts per the SID. Approximately 6;800 feet ATC assigned to climb and maintain 19;000. The power setting and speed I had was maintaining 250 kts. The aircraft alts capped and the speed shot up to approximately 285 kts since the power was reduced but not enough. I disengaged the autopilot; reduced the power; corrected the airspeed deviation and continued to climb as assigned. Cause of this event was due to me being behind the aircraft in climb and getting too behind the automation. Another contributing factor was due to me not flying approximately 80 days leading to a lack of proficiency.[I] suggest pilots who have not flown recently to slow down and make sure they stay ahead of the aircraft to minimize errors and deviations.
