CoreCare

Your software is live. Now it has to stay reliable.

CoreCare is JustJava's production engineering service for software that needs ongoing technical attention after launch.

One night on CoreCare.

Software Health Review

Already have software we did not build?

We can take responsibility for existing software, but not blindly.

Before CoreCare begins, JustJava performs a technical health review to understand the codebase, architecture, deployment, dependencies, documentation and operational condition.

Responsible engineering starts with knowing what we are taking responsibility for.

Have software that needs to be done properly?

Tell us what the business is trying to achieve. You do not need to arrive with a technical specification. If the opportunity is a good fit, we will help turn the business requirement into an engineering problem we can solve.
