Final Degree Project
Mobile and web platform that helps firefighters find an operational hydrant in seconds during an emergency.
During an intervention every second counts, yet finding a working hydrant relied on paper maps and outdated records. That is what the Granada firefighters I spoke with told me: they had no reliable source of truth about the real state of the hydrants.
ABI combines a mobile app for field crews and a web panel for municipal administrators, both working on the same real-time data. In emergency mode, the app instantly shows the three nearest operational hydrants.
Rendering hundreds of markers in React Native tanked the frame rate, especially on Android.
I switched to static image markers, disabled view tracking, memoized components and grouped points with clustering.
700+ hydrants at a steady 60 FPS.
Each municipality must only see and manage its own data, and the information is sensitive.
I built security in from the start: JWT authentication, HTTPS, encrypted passwords, role-based access and per-municipality data isolation, designed with GDPR in mind.
A foundation ready to be offered as SaaS to municipalities and fire-department consortiums.
An app that works doesn't guarantee it's useful in a real emergency.
I validated it with a Nielsen heuristic evaluation and hands-on testing by an active firefighter, and turned their feedback into concrete improvements.
4.6/5 in the heuristic evaluation.
