Custom Application Development and Maintenance

The Client

The client is a leading online credentialing solutions organization in the logistics industry in the USA.

‍

The Challenge

• For the past 7-years, the client had desktop software built on Angular 5 and lonic for the front-end and Dot Net and MongoDB for the backend server.

• Adding new features within the software and maintaining the software was getting problematic and time-consuming due to the complexities of the application.

• The team faced a critical challenge with the application performance as it was getting slow.

• The UI/UX maintenance was becoming a problem for the team as the software had old non-scalable technologies.

• The team was looking for customized enterprise software that is agile, scalable, can work on any device, and is SaaS-friendly.

Calpion's plan of action

The client reached out to Calpion and explained their situation. They wanted a Custom application development solution implemented within 6-months to stop the loss in operation costs. Calpion analyzed the challenges and drafted a new Custom web application development software design to build an agile and scalable application that incorporates existing functional features while incorporating new technologies and features. Based on a redesigned technical infrastructure that employs hierarchy, user interface adaptable design, and a content management system approach.

• Calpion immediately set up a team of developers, and designers backed them up with a world-class Project Management Office (PMO) team.
• The PMO team prepared the business requirement definition (BRD) documents in collaboration with the client and passed them on to the development and design teams.
• The PMO team monitored the deliverables through the Project Management tool to track the deadlines.
• The design team designed the visual designs and app functions and collaborated with the client for approvals. Once approved, the designs were forwarded to the development team to create the software as per the guidelines.
• The PMO team collaborated with the client from time to time to provide the latest update and feedback about the progress.
• Calpion utilized the AWS platform to maintain backend and front-end application infrastructure and make the software agile and scalable.
• With the help of the latest cutting-edge technologies, Calpion added new features and made the application more performant and easier to use with great UI/UX.
