Tell me what you're working on and where it's getting stuck. I'll tell you straight whether I can help, and which studio the work belongs to. You talk to the person building your system, not a gatekeeper.
30 minutes for an intro call, 15 if you only need a quick answer. Monday to Thursday evenings, India time; the picker shows them in yours.
Times are shown in your time zone. You get one email with the meeting link; reschedule or cancel from that email.
