DSA Trackeris a free, ad-supported DSA practice tracker for anyone preparing for software-engineering interviews — students, career switchers, working engineers brushing up before an interview loop, all of it. We don’t invent new problem sets — we reorderthe well-known ones (Apna College, Love Babbar 450, Striver A2Z) around the role you’re actually preparing for, then layer AI skill-analysis and progress tracking on top.

What you can do here

• Practice 370 curated problems, filtered by difficulty, topic, sheet, status, and free-text search.
• Get a role-specific reorder— pick “SDE”, “Backend”, “ML Engineer”, etc., and the same problems are resequenced by relevance to that role.
• Run an AI skill check — paste your resume or skills paragraph and get a match score, missing skills, a 12-week roadmap, and the DSA topics to focus on first.
• Track progress honestly — streaks, heatmap, per-topic mastery, leaderboard. AI falls back to a deterministic rule engine when upstream providers are rate-limited, and we tell you when that happens.

Why this exists

Most DSA sheets dump 450 problems on you and walk away. DSA Tracker asks one question first — “What role are you preparing for?” — and uses that to pick the order, the roadmap, and the AI guidance. The goal is to remove the “what do I do next?” paralysis without inventing yet another problem list.
