37, switching into dev from a totally unrelated field. Is my age the thing that quietly sinks me?

Not asking for pity, asking honestly. Every 'I switched careers!' story I read is someone who was 26. My skills are coming along, projects are going, but I keep picturing a 28-year-old hiring manager doing the math on my resume and quietly passing.

Has anyone actually switched in their late 30s and landed something? Did age come up at all, or is it mostly in my head?
