Hi everyone,
I have used AI for formatting this post.
I have around 5 years of experience working in Mainframe technologies, mainly COBOL, JCL, batch support, production support, and related maintenance activities.
I want to move to back end development.
I’m a bit confused about the best way to transition from mainframe to backend, especially considering my experience level.
Some of the questions I have:
Which backend stack would be better to learn now (Java/Spring Boot, Python, Node.js, etc.)?
How difficult is it to switch from the mainframe after 5 years?
Should I target service-based companies first or directly for product-based companies?
What kind of projects should I build to make my profile stronger?
How should I prepare for interviews as someone coming from a non-backend background?
Is cloud knowledge (AWS) necessary for backend roles nowadays?
I’m willing to put in the effort and learn properly, but I want to follow a realistic roadmap instead of randomly learning technologies.
Would really appreciate advice from people who made a similar transition or are currently working in backend development.
Thanks in advance!
