Human Factors
I was departing runway XX at ZZZ. Noise abatement procedure calls for no turns below 1;000 feet. I was climbing out at 80 Mph when a warning flashed on my ADSB in software on my tablet. I was nose high and did not see the traffic approaching me from the NW and below my altitude. When I looked left; I saw a twin engine aircraft climb through my altitude and fly past me on a southeast heading. I was just starting my crosswind turn when I first saw the aircraft. They were not on the CTAF frequency even though they were flying through the pattern for ZZZ. After I was sure the plane was clear; I resumed my turn to downwind for runway XX and then checked the ADSB in information on the target to be sure I had seen the correct N number as it flew by. The N number I wrote down was the same N number that showed up for that target on ADSB-in. It was disconcerting to have a plane fly under me and so close laterally while I was in the pattern.
A pilot departing a non towered airport reported a NMAC with climbing traffic not communication on the CTAF.
