I realized recently that I

I realized recently that I couldn't find some of my oldest childhood friends online. Instagram handles change, Facebook feels like a ghost town, and the internet,despite connecting the whole world,somehow forgot about the class of 2012. So, I decided to build a place for us.

The Solution: Meet Catalog. A mobile MVP designed not as a noisy social network, but as a quiet sanctuary. No endless feeds, no gamification. Just a calm, nostalgic space (built with a strict Notion & Daylio-inspired design system) to find your old school, claim your class, and share memories.

The "Messy Middle" (How I built it): For the challenge, I didn't just want to drag and drop. I wanted to push the technical limits:

The Architecture: I used for the first time the Model Context Protocol (MCP) via Cursor (first time too) to inject a strict design system directly into #Flowstep using prompt engineering.

The Reality: Building is messy! As you can see in my demo video, my laptop battery almost LITERALLY died mid-generation, and the AI created some duplicate branches. But that’s the beauty of being a Product Engineer. I jumped into the Flowstep canvas, cleaned the architecture, exported the native layers into Figma, and manually wired the final prototype to perfection.

What's Next & Let's Connect: This UI prototype is just the beginning. With my background in Software Engineering and Data Science, I am going to build the real backend for this. To ensure safety, I plan to integrate an OAuth verification system (like Instagram API) so users can securely verify their identities before seeing sensitive contact info.

I want to see this project come alive so I can finally find my long-lost friends, and I hope it helps you find yours, too.

Want to collaborate on making this real?I will make this a study-case on my blog where you can see more updates or reach out Flowstep link:https://app.flowstep.ai/file?activeFileId=df531572-26cc-49ef-986a-40cbbf6bbee5 Social post (instagram) link: https://www.instagram.com/reel/DbewKGCICBv/?igsh=MTc4a2NvMjhma3c2ZA== Personal page: https://garrulous-build-logic-flow.base44.app/
