Project Summary

Kellton developed and redesigned a refrigerant-tracking firm's legacy web platform into a microservices-based web application, advising on technology choices such as Angular for the frontend and Laravel Lumen for the backend. The engagement began in September 2018 and moved from an intense development phase into sustaining work. The vendor added QA and project management during the engagement, which improved product quality; the resulting product has won four awards.

Key Challenges

Legacy product (10–15 years old) built on outdated technology
Platform lacked scalability and was difficult to maintain and extend
Needed to redesign the system from the ground up and select appropriate technologies
Required partner support for design and development

Project Deliverables

Web application
Microservices architecture
Angular frontend
Laravel Lumen backend
API integrations

Project Solution

Kellton recommended and implemented a microservices architecture to replace the client's monolithic legacy web application, splitting functionality into small services that communicate via APIs. They advised using Angular for the frontend and Laravel Lumen for backend services and developed the web application accordingly. The engagement included scaling the team over time and transitioning into a sustaining/support period while remaining involved for new major features.

Project Outcome

The product has won four awards.
Product quality improved after QA resources were added.
The team’s extra effort reduced expected delays (project finished a couple of weeks late rather than months).
