Problem Solving as Engineering Practice

Competitive programming is not the same as day-to-day software engineering, but the thinking transfers well.

Solving hundreds of problems gave me a habit I still use at work: identify the constraints, name the invariants, handle the ugly edge cases, and only then choose the implementation.

That habit helps in system design too. A distributed lock, a reconciliation pipeline, or an agent workflow all become easier to reason about once the boundaries are clear.

I am less active on LeetCode now than I used to be, but that practice still shows up in how I debug, design APIs, and review tradeoffs.
