How do people who consider themselves as problem solver fair in the industry?

I’ve had numerous jobs spanning different business domains: banking, access management, multi tenant services provisioning, etl pipeline, and much more.

I was also curious enough to deep dive into a problem no matter which layer ranging from clarifying requirements of a project to debugging an application to tracing packets and troubleshooting physical hardware.

I’d say that it’s given me a very interesting and enjoyable career. and insights to almost zero in on the probable root cause on any problems as soon as someone starts to describe their issues. I’ve been able to jump into any unknown projects and debug issues and implement features.

Basic troubleshooting ability, the ability to say I don’t know right now, but I’ll be able to figure it out has paid off well financially and career wise.

Once you reach a certain level it becomes less about the stack itself and more about the bigger picture. What problems for the customer you're solving, what's the UX. If the stack there for historical reasons then just pick up that stack. Business don't generally care about how you solve their problem, they just want it solved. If you have to pick up a new stack to do it, then so be it. Is there a demand for that? Businesses still have, and will always have problems they need bespoke software written to solve. Choose whichever you want, you'll be valued either way. Specializing in one field limits the breadth of what you can do but the depth makes you more valuable, just in a different way.
