Hey Dev Community! 👋

As developers, we’ve all been there: staring at hundreds of LeetCode problems or DSA snippets, trying to memorize them right before a big interview sprint. But when the interviewer asks, "Why did you choose this approach?" or "Where would you deploy this in production?", memorized snippets fall completely flat.

That is exactly why I built InterviewPro—a free, open-source speed trainer designed to change how developers prepare for SDE Level 1 roles.

Instead of just giving you code to copy, the platform forces you to drill down into structural engineering communication.

🛠️ The Tech Stack
I built this platform end-to-end to ensure it feels incredibly fast, snappy, and responsive:

Framework: Next.js (App Router) for clean routing and production performance.

Styling: Tailwind CSS with a modern, glassmorphic dark-theme UI.

Icons: Lucide React for consistent, crisp interface indicators.

Tracking: Fully integrated with Vercel Web Analytics to watch unique visitor trends scale live.

🚀 Key Features Built for Devs

The 5-Part Production Matrix The core engine of the platform breaks every single technical question and solution down into five high-value engineering steps:

What it is (The core concept)

Why it matters (The underlying engineering reasoning)

Where to deploy it (Real-world system design application)

Optimization Tactics (Refining the approach)

Enterprise Best Practices (How real production teams handle it)

High-Octane DSA Sprints
We just dropped an upgraded module specifically targeting SDE Level 1 Data Structures & Algorithms. You get full code breakdowns with syntax highlighting that mirrors your native VS Code environment—complete with strict Time & Space Complexity metrics.
Transparent Solo-Dev Flow
To keep this project 100% free and community-driven, I avoided annoying paywalls or corporate pricing structures. I designed a custom, streamlined support layout where mobile users can instantly tip via PhonePe/GPay UPI deep links to help keep the servers running.

🎯 I'd Love Your Feedback!
As a solo developer, building this has been a massive learning curve. I’d love for the Dev.to community to open the link, break the system, run through a few interview rounds, and give me honest code reviews or feature suggestions.

What should I optimize next?

What DSA patterns or features would you like to see added to the matrix?
