Most of our processes are EOD centric, we run a lot of batch jobs (mainly TSO, very little IMS). Integrations are mostly file based but we do both call and expose APIs (“regular REST APIs”) as well as consuming from and producing to Kafka among other things. We integrate with both mainframe and distributed systems on prem as well as “internal” systems hosted on cloud.
We use Git for source control but have a CI/CD solution that is built in house. Quite a lot of other infrastructure is also built in house.
I am mid 30s and am on the younger side looking at the mainframe area as a whole at my employer, however in my team we have several developers is in their 20/30s.
My background is mainly back- and frontend development on the Microsoft tech stack but I have worked, and do work, with whatever is at hand/required. But mostly stuff like .NET and SQL Server on the backend, and Angular/Vue/React on the front end before this.
