Reqflow
Go from confused to confident.
ReqFlow is an interactive engineering playground where you learn by doing, not watching. Explore real system architectures like WhatsApp, Netflix, and Uber, trace live requests, trigger failures, and rebuild systems from memory. Practice System Design, DSA, React Native, and Forward Deployed Engineering with interactive visualizers, interview mode, capacity estimation, drag-and-drop design, AI feedback, and hands-on lessons that prepare you for real engineering work.
👋 Hi Product Hunt!
I'm the solo developer behind ReqFlow.
I built ReqFlow because I felt that most programming courses rely heavily on long videos and passive learning. Students finish hours of content but often struggle to apply what they've learned when building real products or preparing for interviews.
ReqFlow takes a different approach. Every lesson is designed to be interactive, practical, and focused on real engineering problems.
Today the platform includes four learning tracks:
🚀 Data Structures & Algorithms with interactive visualizers
🏗️ System Design using real-world architectures and a drag-and-drop builder
📱 React Native with practical lessons for building production-ready mobile apps
🤖 Forward Deployed Engineering, covering AI applications, RAG, MCP, automation, and modern engineering workflows
The goal is simple: help students build practical software engineering skills instead of just collecting certificates or completing another video course.
This is just the beginning, and I'm continuously improving the platform based on feedback from students and developers. I'd love to hear what you think, what you'd like to see next, and how I can make ReqFlow even better.
Thanks for checking it out! ❤️

Who hunted Reqflow?
Reqflow was hunted by Fouzia Naaz. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
