Developing integrated applications for business users means connecting different systems into a unified whole. Our solutions link web and mobile applications to business logic on the backend, enabling real-time access to data and workflows across platforms. All components share a single database, unified user management, and a structured API layer to ensure secure and accurate data exchange.
Our applications are built with two core components – web and mobile – both connected via a REST API to a PHP backend. We use MySQL as the database and OAuth2 with JWT tokens for secure authentication. Mobile applications are developed using the Ionic framework, allowing shared code across iOS and Android while maintaining a native user experience.
Example Implementations
For AVIS rentacar, we developed an application to document the condition of vehicles during pickup and return. Users upload photos and status information via a mobile app, which syncs in real-time with the backend. The web interface allows fleet management, reporting, and data analysis.
For IGH Institute, we delivered a reporting tool for field engineers. Through a mobile app, engineers log observations, upload photos, and mark geolocation. Reports are synchronized with the central system and reviewed via a web interface with options for PDF export and automated distribution.
We’ve also built internal communication and operations tools, including apps for time tracking, field presence, absence requests, and job orders. A single backend ensures consistency across web and mobile, allowing staff to work efficiently regardless of location.
A more complex system involves ferry ticket sales. This app integrates with payment gateways, manages schedules and reservations, issues digital tickets, and validates boarding using QR codes. Offline functionality ensures that field staff can continue working without connectivity, with automatic sync once online.
Integration Process
We begin every project with an analysis of user workflows and identify where manual input or delays cause inefficiencies. Based on this, we design system architecture, data structures, and user flows.
Using REST APIs, we connect mobile and web components to the backend. APIs are versioned, documented, and stable. Ionic-based mobile apps consume the same APIs as the web interface, ensuring unified behavior and streamlined maintenance.
Authentication is handled via OAuth2 with token-based access and fine-grained permission control. We use authorization code flows and refresh tokens to provide a secure but seamless user experience.
Data is stored in a structured MySQL database, optimized for fast retrieval and cross-referencing. All entries made via the app are immediately visible in the web interface and vice versa.
We implement logging, error tracking, and system alerts. Clients are also given access to dashboards and analytics tools for insight into system use and user behavior.
