Flashify DSA is Live: AI-Powered DSA Interview Prep
Interactive flashcards with GPT-4o-mini feedback, 50+ curated problems, and pseudocode focus to master algorithmic thinking without rote memorization.
DSA interviews can trip up even strong developers with curveballs like tree inversions, so I built Flashify DSA—an AI coach emphasizing thinking over copying code. It offers smart feedback on your approach, a bank of 50+ problems from easy to hard, and pseudocode-first learning to build real problem-solving muscle. This post dives into its features, clever hacks, and the tech behind it.
Key Features
1. AI Feedback with GPT-4o-mini
Submit your pseudocode or solution for targeted analysis that critiques your approach, not just syntax—limited to three reviews daily to encourage deliberate practice.
2. Curated Question Bank
50+ DSA problems spanning arrays, trees, graphs, and more, with interactive flashcards for spaced repetition and progress tracking.
3. Pseudocode-First Learning
Focus on algorithmic logic before implementation, training the interview mindset where explaining thought process wins.
4. OTP Login and History Tracking
Seamless OTP authentication (check spam!) with local storage for user history—no servers, pure frontend jugaad.
Cool Hacks and Product Thinking
Testing clutter? A worker auto-deletes unverified accounts, honoring laziness efficiently. Product instincts kicked in during development, sparking debates between my dev and PM sides to prioritize sticky learning over answer-dumping platforms.
Tech Stack
Powered by React and Vite for snappy UI, AWS for backend muscle, and NextAuth for secure sessions. Local storage handles history, keeping it lightweight and private.[4]
