Inspiration
The idea for Casa Link came from my own home search. Between endless Zillow/redfin/realtor tabs, texts with friends and family, google sheets trying to track it (not helping much), and screenshots scattered everywhere, the process was overwhelming. It felt like there should be an easier way to keep track of conversations tied to specific homes without the chaos of group chats and lost notes. That spark turned into Casa Link.
What it does
Casa Link organizes the home search process by tying chats, notes, and decisions directly to each property. Instead of endless back-and-forth messages, everyone involved can collaborate in one place. Whether they’re comparing houses or just debating over the dream kitchen vs. the questionable bathroom.
How we built it
Casa Link is built with React Native for cross-platform mobile development. The backend runs on Firebase services, including Firestore for real-time data, Firebase Auth for user management, and Firebase Storage for media. We also integrated RevenueCat to manage subscriptions and power a seamless paywall for advanced features like unlimited image uploads and chats. The app’s design focuses on simplicity and clarity, with Tailwind-inspired styling to keep things consistent and clean.
Challenges we ran into
- Designing an intuitive experience that feels natural for something as personal (and stressful) as house hunting.
- Keeping Firebase rules secure while still allowing fast real-time updates.
- Balancing the technical demands of chat + property data without overcomplicating the UI.
- Time. Building as a solo founder/engineer means wearing every hat, from product design to backend setup.
Accomplishments that we're proud of
- Creating a simple, focused solution to a real problem I personally faced.
- Building a working cross-platform app as a solo developer.
- Early testers have already shared feedback that the app makes their home search less stressful.
- Iterating quickly. Adding apartment support after initial feedback.
What we learned
- The importance of user feedback early. It shaped features like the Pros and Cons camera.
- Firebase can power a lot of functionality quickly, but requires careful thought around data rules and scaling.
- Design matters. A clear UI makes even complex data (like properties + group decisions) feel approachable.
- Sometimes constraints (like being laid off) open the door to opportunities to build what you believe in.
What's next for Casa Link
- Expanding features for realtors: better ways to manage client properties and feedback.
- More integrations with popular listing platforms for faster property import.
- Smarter tools: sentiment tagging, decision summaries, and AI-powered insights to help groups reach consensus.
