Client
Our client is a forward-thinking e-commerce company with a strong online presence in the retail industry. They wanted to innovate their business model by introducing a mobile app with integrated point-of-sale (POS) capabilities. The objective was to offer customers a unique shopping experience where they could exclusively purchase products through the mobile app and conveniently pick them up at designated offline pickup points.
Challenge
Integrating online shopping convenience with a localized pickup option, all without physical stores, posed a significant challenge. The objective was to develop a secure and user-friendly mobile app that seamlessly combined online ordering and offline self-pickup. To achieve this, the solution needed to incorporate an intuitive interface for easy product browsing, order placement, and secure online payments. Integration of POS capabilities was essential, enabling customers to select nearby offline pickup points during checkout. This required a robust system for efficient inventory management, streamlined order processing, and secure payment transactions.

Process
1. Project initiation
The project began with productive meetings between the client and the development team. A skilled project manager and experienced business analyst were assigned to lead the mobile app development project, with a focus on integrating POS functionality. During the phase, clear goals, requirements, and timelines were defined through collaborative discussions with the client. Effective communication channels were established to facilitate seamless information flow between the client and the development team. Additionally, specific deadlines and budget constraints were set to provide a structured framework for the project.
2. Documentation and design
After researching the client’s business model, target audience, and competitors, the development team identified key features for the app, including sales reporting, customer engagement software, and integration with inventory management system.
Next, the team documented the requirements, features, and technical specifications, creating a comprehensive plan for the app’s development.
Simultaneously, an UX/UI designer created a mockup of the interface, focusing on an intuitive and visually appealing design that aligned with the client's branding. Feedback from the client was incorporated to ensure the final design would meet their expectations.
While designing the interface, the team also worked on devising a technical solution that would fulfill the identified requirements. They mapped the desired features to the chosen technology stack and architecture, aiming to optimize performance, scalability, and security. The goal was to seamlessly integrate the POS functionality into the app, providing a robust and efficient solution.
3. Development
With a focus on building trust and transparency, the development process adopted an Agile methodology. This client-oriented approach emphasizes collaborative iterations to ensure the client’s satisfaction and active involvement throughout the development journey. By delivering the solution incrementally, Modsen fostered open communication, welcomed feedback, and readily adapted to evolving requirements. The development process encompassed the following steps:
Infrastructure
To ensure the safety of customer data and adhere to PCI requirements, the team focused on establishing a secure application environment. They implemented industry-leading technologies and best practices to safeguard sensitive information. The developers began by setting up a secure and reliable data storage system using PostgreSQL, a trusted database management system. This choice provided scalability and data integrity, providing a robust foundation for storing and retrieving customer data. To protect data transmission, the team implemented advanced encryption protocols, such as TLS (Transport Layer Security). By encrypting data during transit between the mobile app and backend servers, they prevented unauthorized access and safeguarded customer information. In addition to secure data storage and transmission, Modsen engineers followed strict access control measures to protect the application environment. They regularly updated software components, performed security audits, and applied necessary patches to address any potential vulnerabilities.
Robust app architecture with Flutter and .NET
Creating a seamless user experience across different platforms was crucial for the client. The development team opted for the Flutter framework and Dart programming language to build the app for both iOS and Android using a single codebase, saving valuable time and effort.
To acieve visually appealing and responsive interfaces, Modsen experts made great use of the Flutter Material Design Widgets library. By leveraging these pre-built UI components, a modern and intuitive look for the app was crafted, guaranteeing an engaging user experience.
Efficient state management and optimal performance were also high priorities. That’s why the team integrated the Provider package, a powerful tool that enabled effective handling of data changes. This ensured that the app remained responsive and consistent throughout.
Seamless integration with backend services and smooth handling of API requests were achieved with the Dio package, a reliable HTTP client. It facilitated fast and secure communication between the app and the server, ensuring reliable data exchange.
In addition to the frontend development, the backend was built using the .NET framework. PostgreSQL was utilized as the database for secure and scalable data storage. To guarantee secure user authentication and authorization, authentication protocol JWT (JSON Web Tokens) were implemented. Integration with payment gateway Stripe enabled secure and convenient payment processing within the app. The team leveraged the scalable infrastructure and storage services provided by AWS to ensure reliable performance.
Iterative lifecycle: from coding to testing to deployment
To facilitate a streamlined development process and quick time-to-market, an iterative approach was adopted. The project was divided into 2-week sprints, allowing for focused work on specific features and delivering incremental value to users.
During each sprint, Modsen developers diligently implemented the identified features, following coding standards and best practices. This resulted in clean and maintainable code, laying a solid foundation for the app’s functionality. A dedicated QA team conducted comprehensive tests to identify and address any issues early on.
After successfully completing each sprint, the implemented features were deployed to a staging environment, which allowed the client to review the progress, provide valuable feedback, and make any necessary adjustments to meet their expectations.
Throughout the development process, regular communication and collaboration were maintained with the client. Sprint review meetings were held to showcase the delivered features and gather feedback for continuous improvement.
By embracing an iterative development approach, regular and predictable delivery of new features was achieved. Such flexibility allowed for adapting to changing requirements and delivering a high-quality app within an accelerated timeline.
Verified payment security
To strengthen Modsen’s commitment to security, the product underwent third-party audits and obtained relevant certifications. Independent assessments validated the effectiveness of the security measures applied, including compliance with the stringent requirements of the Payment Card Industry Data Security Standard (PCI-DSS), in protecting customer data.
Acceptance testing
A thorough acceptance testing process was conducted involving both the client and end-users to ensure that all requirements were met and the app functioned as expected. This critical phase validated the app’s performance, functionality, and user experience, ensuring that it successfully met the desired specifications and effectively fulfilled the needs of its intended users.
4. Closing
With all requirements successfully fulfilled, the app development project reached its final stage, indicating its readiness for production deployment. Here is an overview of what the team delivered at this stage:
