Efficient Device Evaluation for Large Enterprises

A major leasing company approached us to ensure efficient valuation of returned leased equipment. After 18 months of development work, we have now rolled out the system.

Customer Requirements and Our Solution

Our customer required a solution that allows leased devices to be evaluated quickly and easily. The goal was to determine whether devices need repairs and the potential costs involved. We developed a system that meets these requirements:

User-Friendly Interface

• Simple Input: Users can enter or scan a device's serial number to get immediate information.
• Intuitive Navigation: The minimalist interface allows automatic navigation through evaluation questions, with progress saved even if the browser is closed or the page is refreshed.

Extensive System Features

• Report Generation: Reports are automatically sent to a central repository upon completion of the evaluation.
• Control Panel: A clear dashboard allows management of system data and numerical evaluation values.
• Keycloak Integration: Secure management of tenants, users, and roles through Keycloak integration.

Technological Foundation

Our system is based on a robust microservice architecture using state-of-the-art technologies:

• Backend Technologies: FastAPI, PostgreSQL, RabbitMQ, Redis, and Docker.
• Automated Imports: Regular and automatic data updates via Webhook.
• Storage and Processing Optimization: Utilizing Redis, RabbitMQ, and AWS S3 for efficient data processing and storage.
• Optimized Database Access: Transaction summaries and indexing speed up database queries.

Operation and Scalability

• AWS Hosting: Our system runs stably and scalably on AWS, supported by load balancers and optimized resources.
• CI/CD Pipelines: Continuous integration and deployment ensured by GitHub and Terraform.
• Comprehensive Testing: Backend services are thoroughly tested and configured via Docker to ensure maximum reliability.

Results and Benefits for the Customer

The result of our work is a highly functional system for evaluating leased devices, significantly simplifying and accelerating the evaluation process:

• Efficiency and User-Friendliness: The evaluation process is intuitive and fast.
• Secure User Management: Keycloak integration ensures secure and reliable management of users and roles.
• Robustness and Scalability: Modern technologies and Docker containers make the backend robust and scalable.
• Timeliness and Accuracy: Automated imports and reports ensure always up-to-date and precise evaluation data.
• Fast Data Queries: Optimized database access significantly speeds up query processes.
• Stable Environment: Our DevOps setup on AWS provides a stable, test-backed, and flexible development environment.

With this tailored system, we have created a solution that meets our customer's requirements and makes the evaluation process of leased devices more efficient and user-friendly. This project underscores our ability to translate complex industry requirements into powerful technical solutions.
