Comparing private lease car offerings that put the user first

Private car leasing has been an emerging trend over the last couple of years and a growing number of manufacturers and third-party providers are offering private car lease services. For consumers, this results in an enormous amount of work of comparing prices and terms before being able to pick the right private lease car and contract.

Comparing lease cars, however, is a complex challenge. Cars are a complex product if you think about the fact that a single car can have multiple models all with their own set of options and accessories. Next to that, every lease car provider has their definitions of mileage, contract time, and additional prices for specific options or packages so we needed to try and get a unified data model for all this information and be able to search, compare and filter through this information. reference case

The right people to get the job done wanted to validate their concept as quickly as possible and asked Luminis to help them turn their concept into a usable Minimal Viable Product (MVP).

A team consisting of a frontend engineer, a backend engineer, a search engineer, a tester, and a product owner took an agile approach to deliver the MVP. In small iterations, together with the founders of, they developed parts of the comparison website. All with the following goals in mind: it needs to be fast, fully responsive, and able to quickly scale in case of onboarding new lease car providers and customers.

The Luminis team is very capable on AWS, FE and Backend as well as discipline/structure in the way of working. The team delivers on time and it's transparent to me as a customer on planning and costs. Several things went different than planned - the true shine of Luminis was in how they solved those problems themselves pro-actively. An exception unfortunately in this industry. Keep up the good work!”

A fully responsive website using Cloud solutions to enable future expansions

A fully responsive comparison website was developed based on React, a JavaScript library for building rich user interfaces.

React allowed the team to create UI components that could be reused across different sections of the comparison website. The website itself is leveraging several (REST) APIs for displaying car or contract information, search and filtering results, and processing offerings. New features and fixes for the website can be developed and deployed at a high pace by leveraging Continuous Integration and Continuous Delivery pipelines.

Amazon Web Services (AWS) was selected as the preferred cloud provider. Within the AWS cloud, the team leveraged existing managed services like Amazon Elasticsearch Service, Amazon RDS, Amazon CodePipeline, and Amazon ECS. This allowed the team to get up and running quickly and let them focus on building customer value instead of managing infrastructure. By taking the above steps we’ve ensured that future expansions can be implemented efficiently and quickly.
