Build your application

Objective

Build custom applications or APIs that enable deeper interaction with your data. From AI-powered tools to line-of-business apps, we deliver solutions tailored to your specific needs.

Approach

Specification-first development using OpenAPI. We design the user experience, create interactive prototypes, write executable specifications, then build and test iteratively.

Collaboration

Your team defines the business need; we translate it into a tested, deployed application. Pair programming and code reviews ensure full knowledge transfer throughout.

Key activities

Application Development follows a specification-first approach. We define the API contract using OpenAPI, design the user experience with interactive prototypes, and build iteratively with executable specifications ensuring correctness at every stage.

But don’t just take our word for it.

We pride ourselves on our customer relationships. Here's what they had to say about us.

When we selected Microsoft Azure to run business critical, client facing web applications in the financial services sector, endjin provided us with the day-to-day in-depth expertise we needed to keep our software & hosting environment relevant, reliable & robust.

We can now spend our time and energy finding new opportunities and building new relationships, confident that our platform can scale to meet any challenge.

We recently completed a Microsoft Solution Assessment and line-by-line code review. The solution and code were rated high-quality and well-constructed.
