resQ - Project Story

About the Project

resQ is a one-tap emergency platform that dispatches high-quality voice notes and precise GPS coordinates to responders. It is designed to be a reliable lifeline in high-stress situations.

Inspiration

Driven by the security challenges in Nigeria, resQ address the issue of slow and unreliable emergency response times. In crises, victims often have seconds to react. resQ ensures that while escaping to safety, users can instantly alert a network of responders with their exact location and situation context.

How I Built It

Built with React Native (Expo) and NativeWind, resQ leverages native hardware for low-latency GPS and audio capture. It uses Clerk for secure identity management and an Elysia (Bun) server for high-performance data handling.

Challenges

Our primary challenge was synchronizing hardware requests. We implemented a "wait-and-lock" mechanism to ensure high-accuracy GPS coordinates are secured before any dispatch is allowed, preventing "blind" emergency signals. We also optimized for network reliability by adopting a robust record-then-send model, better suited for variable connectivity.

What I Learned

I learned that in emergency technology, minimalism is safety. Removing friction is more important than adding features. I also gained experience in hardware orchestration and building for high-reliability environments.

Final Thoughts

To be honest I had always wanted to build something like this for a while now, and even though the hackathon gave me the final push I needed, I'll still keep working on resQ even after the hackathon. The problem of insecurity is real and real lives are being lost. If resQ can save one life, just one, then all of this would be worth it, win or lose.
