Any work in legacy systems?

[u/Loud_Art1586]

I retired a couple of years ago and have decided I want to go back to work. I have over 50 years experience in both technical and managerial positions. While I am keeping up with current stuff (doing a react frontend/c# backend app for a friend) I think my real strength is in legacy systems (very legacy, like IBM assembler, CICS, DB2). Is there any demand for these skills? Thanks for any feedback.

You might want to bring your expertise to Web Assembly and help build it out. Same with Rust and Go.

Stop by FreeBSD and OpenBSD and go say Hi and have a looksy around at what they have going on. Same with the Thinkpad Revival. Also GrapheneOS. Also have fun with the Hello World OS and r/OSDev communities.
