Building a Local-First Interview Prep Gym to skill growth

Interview prep usually fails from missing rhythm, not missing problems. I had study plans, LeetCode lists, and scattered notes — but no single system that turned *today* into a concrete action and kept a record of what I actually learned. So I built **dsa-problem**. a local-first workspace that treats interview prep like gym training — daily drills, spaced repetition, honest logging, and tools that stay in your repo instead of on a SaaS dashboard. This post explains why it exists, what it does, and how the design is meant to improve skill over time.
