Startup progress
Coding interview practice that feels less random and more deliberate.
CodeGrind organizes original interview-style problems into focused clusters so you can practice arrays, strings, trees, graphs, dynamic programming, and other DSA patterns with a clearer progression than blind problem grinding.
CodeGrind is the platform. Code Breach is its first live featured game: an actual tower defense coding experience where you solve real problems, protect your base, and build skills that carry into beginner learning paths, problem clusters, and interview-ready practice.
Start with a simple Code Breach getting-started problem on the homepage, then branch into the rest of CodeGrind through Beginner Learning Paths or Interview Prep Clusters.

What You Get
Original interview-style challenges grouped by topic and difficulty.
Classic editor and coding game modes for different practice moods.
AI-assisted hints paired with execution feedback so answers can be checked, not blindly trusted.
Progression, XP, streaks, and leaderboards that make daily practice easier to sustain.
Practice by pattern, not by panic
The strongest interview prep platforms build clear topical pathways. CodeGrind follows that pattern with challenge clusters that help learners revisit core DSA patterns instead of jumping between unrelated questions.
Turn practice into a repeatable loop
Solve a problem, run real test cases, ask for guidance when stuck, verify the result, and keep moving. That loop is designed for interview prep, daily challenge habits, and learners who need structure without losing momentum.
Use AI without outsourcing judgment
CodeGrind positions AI as a practice partner. The goal is not to paste answers, but to learn how to question suggestions, validate code, and build the problem-solving instincts interviews actually test.
