The Challenge: Ensuring a Reliable, Offline-First Data Collection Platform

In Airotect, set out to develop a scalable field data collection platform that functions seamlessly in remote locations with limited or no internet access. As the QA Lead, I played a critical role in ensuring the platform's stability, data accuracy, and synchronization. I led testing efforts to tackle key challenges such as:

🔴 Real-time & Offline Data Synchronization: Ensuring smooth transitions between offline and online modes.
🔴 QR Code-Based User Authentication: Enabling seamless user verification in the field.
🔴 Batch Processing & Bulk Data Submission: Validating large-scale data uploads.
🔴 Cross-Device & OS Compatibility: Ensuring flawless functionality across web, iOS, and Android.

Solutions & Approach

✅ Implemented Robust Offline Data Sync Mechanisms:
- Developed and executed test cases to validate offline data storage & auto-syncing.
- Simulated real-world field conditions to ensure seamless data recovery.

✅ Optimized QR Code Scanning & Authentication:
- Ensured high accuracy in user validation under varying lighting & connectivity conditions.
- Automated test cases to validate QR-based login and batch registration.

✅ Enhanced System Performance & Bulk Data Handling:
- Conducted load & stress testing to optimize batch data submissions.
- Validated backend processing to handle simultaneous requests from multiple users.

✅ Ensured Seamless Multi-Platform Functionality:
- Conducted extensive cross-browser and device testing using BrowserStack.
- Verified UI & functionality across various screen resolutions.
