I need an Android app that lets my security team tap preset NFC tags while on patrol and instantly pushes the tag ID, exact date-time, and GPS location into a Google Sheet. The core workflow is simple: phone out of pocket, tap the tag, data appears live in the sheet. Key requirements • Main use case is tracking patrols, not general attendance or inventory. • Each tap must trigger a real-time location update so I can see where the scan happened without delay. • Users must sign in first; a lightweight email or phone based authentication is fine as long as individual scans can be traced back to the user. • When a scheduled patrol point is missed or a scan happens outside the allowed geofence, the app should raise an alert notification on the device and optionally by email. Helpful context and preferences I am comfortable working in Google Workspace, so staying native to Google Sheets and the Google Sheets API is ideal. If Firebase Cloud Messaging or similar is the easiest path for push alerts, that works for me. Code can be in Kotlin or Java and should compile cleanly in the latest stable version of Android Studio. Deliverables and acceptance criteria 1. Android APK plus full source code. 2. Google Sheet template already wired to receive data. 3. Documentation showing how to add or change NFC tag IDs, patrol points, and alert rules. 4. Successful field test: scanning at least ten tags from three different user accounts and seeing data populate live with correct coordinates and timestamps, while a missed scan triggers an alert.

I've integrated GeoServer and built map-based applications for a complex PropTech platform. Your patrol tracking app needs robust location capture and real-time geofence alerting. I can architect and deliver this critical solution with production-grade reliability. My solution will use React Native with Expo and JavaScript to build a high-performance Android APK, leveraging my full-stack expertise for the backend logic and reliable API design. We will use a lightweight Firebase Authentication for user sign-in, ensuring every scan is traceable. The key is using the Google Sheets API directly for the data push, ensuring native Google Workspace compatibility. Crucially, I will implement immediate location fetching on NFC scan to guarantee the scan location is accurate. Geofence and missed patrol point alerts will be managed efficiently using Firebase Cloud Messaging (FCM) for real-time push notifications, integrating the optional email alert logic on a small Node.js backend. This architecture guarantees a fast, scalable, and fully auditable system. I spent 5 years building a complex PropTech platform from scratch for UK developers, and I hold a 6.4/10 earning rating with a 5.0 star rating across just 15 Freelancer.com projects, proving I successfully deliver high-value, production-grade work that justifies your investment.I'm available to discuss today.

With 6+ years building production-grade Android apps (primarily in Kotlin) and deep experience integrating NFC, real-time location tracking, Google Sheets API, and Firebase, I can deliver exactly what you need—secure, reliable, and field-ready. Here’s how I’ll approach your project: Build a clean, focused Android app (min SDK 24+) that reads NFC tag IDs instantly on tap. Capture precise GPS coordinates and UTC timestamp at the moment of scan—no delays. Implement lightweight email/phone-based auth (Firebase Auth) so every entry is user-tracked. Push data directly to your Google Sheet via Sheets API (OAuth 2.0 secured). Add geofencing around patrol points: if a scan occurs outside the allowed zone—or is missed during a scheduled window—the app triggers a local notification and, optionally, an email alert via Firebase Cloud Messaging. Provide a pre-configured Google Sheet template, full source code (Kotlin, Android Studio latest), and clear admin documentation for managing tags, patrol routes, and alert rules. I’ve built similar field-force tracking systems before, and I understand the need for zero friction during patrol—your team shouldn’t fiddle with the app; it should just work. I can start immediately and deliver a tested, documented solution within 15–20 days. Let’s get your security team equipped with a tool that’s as dependable as they are.
