Transforming On-Site Training Assessments with a Seamless Digital Solution
Project Overview
In today’s fast-paced industries, skill assessments play a crucial role in evaluating and certifying professionals. Our client, a leading training and certification provider, sought to modernize their assessment process, which was previously paper-based, slow, and prone to errors. They needed a robust, mobile-first solution that could enable assessors to conduct evaluations seamlessly, even in remote locations with poor connectivity. That’s where Magnatesage stepped in! With our expertise in mobile application development and cloud-based integrations, we designed and developed a Flutter-powered cross-platform assessment application for iOS, Android, and PWA. The result? A streamlined, secure, and scalable digital assessment system that transformed the way skill evaluations were conducted.

Objectives
- Enable digital, real-time assessments on mobile devices.
- Implement an intuitive, user-friendly interface for assessors.
- Support offline functionality for areas with limited connectivity.
- Enable photo, video, and audio-based evidence capture for assessments.
- Ensure secure data handling, with automatic uploads and deletion from the device post-sync.
- Integrate with a centralized API to fetch assessments and log assessor activity.
The Challenges
- Remote Accessibility & Offline Mode
Assessments needed to be conducted in low-connectivity zones, such as construction sites, offshore oil rigs, and rural training centers. A pure online solution would not work. - Dynamic Question Rendering
Assessments were not pre-set static forms but dynamically generated from an API. The app had to render custom question types (MCQs, text comparisons, media-based evaluations) on the fly. - Secure & Compliant Data Handling
Captured assessment data, including videos and images, needed to be stored temporarily on the device and securely uploaded before being erased to ensure data protection and compliance. - Multi-Device Optimization
Assessors used both tablets and large-format smartphones, so the UI/UX had to be fluid, ensuring a seamless experience across different screen sizes.
Our Solution
Offline-First Architecture
- Implemented local data caching to allow assessors to complete assessments without an internet connection.
- Automatic background sync once the device reconnects to the internet.
Dynamic Form Generation
- The app fetched assessment structures on demand from an API, rendering different question types dynamically.
- Support for MCQs, True/False, text comparisons, numerical inputs, scenario-based questions (photo/audio/video).
Secure Data Lifecycle Management
- Data encryption for local storage.
- Auto-deletion of data from the device post-upload to maintain compliance.
- Real-time logging of user activities via API for auditability.
Multi-Platform Deployment
- Developed using Flutter for iOS, Android & PWA, ensuring a single codebase with native performance.
- Optimized UX for tablets and large-screen smartphones.
Deliverables
- Mobile App (iOS & Android) – Deployed on App Store & Play Store.
- Web PWA Version – Accessible via browsers (without offline functionality).
- Admin & Assessor Dashboard – API-driven seamless integration.
- Comprehensive Logging System – Secure activity tracking for compliance.
- End-to-End Testing & Support – Ensured smooth deployment & maintenance.
