I spent a year building a DSA learning platform with 111 interactive visualizers. Would love feedback. A few years ago, I failed interviews at Google, Amazon, and Microsoft. The reason was simple: I could code, but I never properly understood Data Structures and Algorithms. I spent almost a year learning DSA after that. During that time, I realized I don't learn by memorizing. I learn by building. And I couldn't find a tool that taught DSA the way I wanted to learn it. So I

Build multiple resume formats and cover letters from a single profile with AI assistance.

Trying to make a career building website Built a résumé (resume) builder that generates 25 different template styles from one profile — free tier, no credit card. I got tired of retyping the same résumé into a different format every time I applied somewhere with a different template requirement, so I built DraftCareer. The core idea: fill in your career profile once, then render it into any of 25 templates (ATS-safe single-column ones and more visual two-column designs) without re-enter
