💡 Did you know that most startups fail not because of bad ideas, but because of weak tech execution? In the past few years, I’ve helped founders in HealthTech, Real Estate Tech, and EdTech turn their early concepts into stable, scalable products that users love. Here’s what I’ve learned: 1️⃣ Simplicity beats complexity, especially in MVPs. 2️⃣ UX matters as much as backend logic. 3️⃣ Clear communication between devs and non-tech founders is game-changing. Curious to know, what’s the biggest challenge you’ve faced while turning an idea into a working product? #StartupTips #ProductDevelopment #FullStackDev #HealthTech #RealEstateTech #EdTech

And finally, here is my entry for the Holiday Challenge: "Snowball Merge Christmas". I made it in 24 hours, so I’m really proud of the result. I built the game using @Rork and created the background music with @Suno . Players drop objects into a box and merge matching items to create bigger ones and score points. As an ex game developer, I have to say @Rork handles game physics extremely well, it would have taken me days to build the same logic in Unity 3D. Happy New Year everyone 🎉🎉🎉

RailRadar is a real-time train detection and arrival prediction system built for communities impacted by rail crossings. Using a distributed network of camera-based tripwire sensors, RailRadar detects train movements at the edge and generates bias-corrected ETAs that adapt to real-world conditions. The system delivers timely, reliable alerts without relying on railroad-provided data or centralized tracking feeds. RailRadar is designed for resilience and accuracy in the field. The platform supports community alerts, operational monitoring, and future integrations with municipal and transportation systems. This project includes full-stack system design, edge sensing logic, backend services, alerting infrastructure, and deployment workflows focused on real-world reliability, not demos.

I love Notion. I just don’t love paying $29/month. That adds up to $348/year. With Claude Code, it’s now realistic to build a personal Notion-style app in a single hour — and build it exactly how you prefer. So I started building Numun Notes for myself: a native app that runs directly on my Mac: ✅ pages + editor ✅ wiki links + backlinks ✅ databases with views (table + kanban) ✅ filters/sorts/grouping + templates ✅ offline-first + fast search Next: I’m merging Notion + ClickUp into one master app, so Numun Notes becomes exactly what I want for productivity.

SoulSync is a concept project exploring memory-based compatibility systems. It works by taking ChatGPT memories or conversation summaries and transforming them into structured, evolving traits. Instead of static profiles, it uses a layered memory model: • past conversational context as input • inferred traits (values, communication style, motivation) • weighted updates as new memory is added Think of it as applying ChatGPT-style memory mechanics to human alignment. Built as a systems and coding exercise to explore memory, state, and human-centric modeling

Several designers had contributed to the product over time, each building on the previous work, which naturally created some inconsistencies and gaps. And my role was to bring everything together, aligning, filling missing states, removing redundancy, and providing clear annotations to support the dev team. Problem People want to turn their closet into cash, but selling is tedious. Writing descriptions, comparing prices, and managing multiple listings takes more time than it’s worth, so great pieces end up sitting in the closet. Solution CNTRL removes the friction. Users snap a photo or search the item, and AI creates the description, shows pricing trends, and recommends the best platforms. The app cross-posts automatically and delists everywhere once the item sells, helping users make money faster with far less effort.

Color contrast isn’t enough on its own, so I’m trying out textures as a second cue to improve accessibility. What are the best practices for using patterns to support users who can’t rely on color alone without making the chart feel busy or distracting?

A community-powered app built on trust. Many immigrants in the U.S. regularly send care packages home, medicine, comfort foods, and small reminders of love. But shipping is slow, expensive, and often unreliable. My client saw families struggling with this and imagined a simpler path: travelers already fly with unused luggage space… What if that space could help someone send something meaningful home, while the traveler earns money in return? This vision shaped our UX approach: • Reduced friction by standardizing luggage sizes, fixed pricing, and simple packing rules. • Strengthened trust through ID verification, clear policies, and plain-language guidelines. • Empowered users with easy reporting tools and transparent expectations that keep the community safe.

Hi fellow designers 👋 Sharing one of my favorite MVPs I designed with an amazing client and team. ChartSync: Patient-Owned Medical Records Problem: When patients switch insurance or move states, their medical history often gets lost, leading to endless PDF searches, duplicate tests, and having to retell their story because their records are scattered everywhere. Solution: We designed a mobile app that lets patients capture files, medications, vitals, and auto-organize their records, and instantly send or receive medical files via QR code with any practitioners without downloading the app. Now in Beta: https://play.google.com/store/apps/details?id=com.chartsync.chartsync&hl=en_US Open to any design or case-study showcase tips from this community. ✨

MCP Market is the financial operating system for AI agents. Launching end of February 2026, it's the first platform that lets autonomous agents actually buy and sell stuff—think Stripe meets AWS billing, but for intelligent software. It solves the extension payment crisis (Chrome killed their payment system), enables agent-to-agent commerce with crypto rails, and meters AI resource usage down to fractions of a cent per API call. Developers can monetize their agents with granular pay-as-you-go pricing while users get "kill switch" budgets to prevent rogue agents from draining their wallets. It's cloud-grade billing infrastructure accessible to individual devs, bridging local AI runtimes with global payments through both fiat and USDC.
