Commercial Support / Consulting

We recognise that although organisations use happily Open Source Software such as http4k, they may gain additional peace of mind from having direct access to expert advice. For this purpose, the project creators offer a range of professional services to support library users in making the most of the powerful feature set which http4k provides, including:

  • System architecture and design review
  • Testing strategy and implementation review
  • Project-level Developer and Team mentoring
  • Troubleshooting integration issues and debugging
  • Kotlin language Developer training
  • Advice on extending or creating custom builds of http4k

http4k Training Courses

The http4k project is a culmination of work on real-world projects in many different industries. Whilst the library is designed to be simple to learn and use, there are many advantages to learning from our mistakes when using it! To this end, the team have developed a significant amount of training materials which can be used to give teams new to http4k the best possible start, especially around the following areas:

  • Advanced testing strategies for individual and entire fleets of services.
  • Building, packaging and deploying http4k apps to on-premises and cloud-based environments.
  • Advanced CI/CD design.
  • Extending the http4k libraries.
  • Configuration of http4k apps for use in data-sensitive environments (customer PII protection etc).

These materials can be delivered both remotely and in on-site sessions. If you are interested in taking advantage of our mistakes, please get in touch at: [email protected]
