(Help) Roadmap to be a better engineer

Hello folks,

Context
If you came here looking for some wisdom, you are wrong.
I am mid level engineer at top MNC company (just by years in the industry and not really by skills). I have spent considerable amount of my time in my current company doing things that require absolutely bare minimum brain and effort.

Cool software and services were made by partner teams, all our org did was onboard to them.
To summarize the experience was mostly from onboarding to another, robotically following the docs given and apply the steps from the doc to our services and call it done. I tried to automate certain things and it was exciting time but that has also saturated.

These things might be good for running overall services in my company but as engineer, i find it dull and boring my skulls out.

Help
I have loads of free time or i am busy doing stuff that doesnt help me grow.
So here I am looking for some guidance to come out of this swamp and be better engineer.

I realize I lack so many skills that a person with my years of experience in IT industry is expected to have.

For starters, knowing async programming, design patterns, HLD. Given the new trends of introducing AI agents everywhere, i feel even more aliened and anxious.
I just don't know where to get started with so many things to learn and so many resources online. It is overwhelming.

TLDR
I so called mid level engineer in MNC but skills at fresher level. I need assistance to build a proper roadmap and stop my career from being a failure.
