Crack LLD in 1 Month (Even With a Full-Time Job)

Somehow… nothing gets finished.


The Problem

If you're working + preparing to switch:

You start learning patterns
You get overwhelmed
You stop halfway

Repeat.


The Shift

One simple realization will change things:

Someday you have to change your life, why not today?


The Rule

1 pattern. 20–30 minutes. Every day. Revise.

No excuses. No overplanning.


My Method (Super Simple)

For every pattern, I only focus on this:

  • Problem → why does it exist?
  • Normal way → how would I solve it without pattern?
  • Pattern → Solution?
  • UML → quick structure
  • Use case → where is it used?
  • Edge cases → where can it fail?

That’s it.


Reality Check

You don't need 5 hours daily or 1 perfect resources

You need:

  • A plan
  • Good notes
  • Daily revision
