1) Tail end of the year - its hard to get full time roles , The hiring definitely picks up after Jan 2nd week or so. 2) Try consulting/contracting - That space is still brimming w hiring. Much faster on-boarding /hiring.
Contracting is not really an option that way in the U.S. market that I've seen, though I'd be interested if you've had a different experience. Either you're contracting through an agency in which case you're applying just like for any FTE job, or you're operating at the high end with an established network. Random gigs at places like Upwork don't pay enough for a major U.S. metro area unless you're willing to hustle…
Smaller companies generally have less red tape to getting contractors, more need (as they are either scaling quickly OR just need something done and don't want to incur high cost of a perm eng). You will need to figure out the appropriate rate (keeping in mind this doesn't come with benefits), but that exercise is left to the reader.
