I don't really think the tech stack matters. I'm a dotnet guy for the most part and have been gainfully employed from it for 20 years, hell going back to vb-6, com etc before dotnet. I get around age discrimination by looking a lot younger than I am. I achieve this by dressing current which doesn't mean trendy, just don't wear that same old sweater to work you've had for 10 years, keep it for family time. New clothes go a long way in this situation. Also don't over dress, that's a huge give-away so no suits. I also shave my head, but if you aren't losing your locks, good for you though you'll want to consider dying it. I also workout a ton, eat well/little (restricted calories, etc),take a ton of vits and sups including metformin, NMN and resveratrol to name a few of the more useful and/or exotic items. I thinking being lean, fit and strong also goes a long way toward conveying both youth and confidence that employers are naturally drawn toward. I mean look when you've been coding for 30 years the problem isn't your abilities, it's how you are perceived by a potential employer. I'm 51 but most guess my age around 38ish.
