Recently laid off at age 48. Less than a month later, had multiple offers with better compensation. Still in tech sector. Two years ago we switched from PHP to Go, which definitely helped.
If you can, what type of code are you writing in Go commercially? Don't worry, you don't have to be specific, I'm just curious =) The libraries have really started to take off for it, and I'm curious if companies are catching up to that, yet.
There are several projects, but the largest is basically a very large specialized content platform. Many sites that have to be fast with no downtime - so Go, K8s, CockroachDB. We also have some machine learning (that's why we kept the Python). Also a few fun, small Raspberry Pi / GoBot things around the office.
Fellow 40-something software dev here. I'd love to ask you some questions about your background & experience. If you'd be inclined, can we chat? My email is in my profile.
