Full featured next gen Clojure test runner.
Clojure & ClojureScript consultancy
Gaiwan seeks to improve upon common IT industry practices, by making deliberate technological choices and focusing on simplicity. They use Clojure, a language known for its high developer productivity. Gaiwan develops several popular Clojure libraries, benefiting their clients, their own projects, and the wider Clojure community, and making the language itself more attractive. By strengthening Clojure and its ecosystem, Gaiwan contributes to enhancing the IT industry as a whole.
We worked with Gaiwan on a complex ClojureScript test runner, and an integration of our product with a popular service. In both instances, they managed their time and resources well, effectively navigated unknowns, delivered high-quality code and communicated clearly. We had nothing but positive feedback, and would highly recommend Gaiwan as a partner.
The Gaiwan team helped us deliver a flawless attendee experience for our conferences. They have created a Bespoke editing and rendering tool to meet ITRev's needs. Created a live streaming conference platform and integrated it into several services and much more. It has been a delight working with them.
We have worked with the Gaiwan team for a large part of our journey. This has included tooling improvements, architectural feedback, improvements to our testing approaches, and one-on-one coaching sessions with our developers.
Gaiwan was comissioned to create the Datomic database driver for Metabase, and worked with Eleven to integrate Metabase into our system. They completely took the pain away from us and let us focus on our core product.
How we give back
Through Gaiwan's educational arm, Lambda Island, all Gaiwan engineers create and maintain several popular Clojure libraries and tools. Check out the quality of our code in these open source projects.
Compare Clojure data structures.
A idiomatic and cross-platform URI library.
Royally reified regular expressions.
A ClojureScript logging library based on goog.log.
Convert ANSI escape codes to Hiccup.
We also maintain community infrastructure, like the ClojureVerse forum and the clojurians-log Slack archive.
Our projects
Lambda Island Open Source
All Gaiwan engineers are active open source contributors, and we have several open source libraries we created and maintain, available through the Lambda Island brand.
These projects often stem from needs we saw in client projects, or in the community in general. By opening them up we make sure we can use these building blocks on subsequent projects.
Heart of Clojure
Gaiwan GmbH is the initiator and legal entity backing the Heart of Clojure community conference. We provide the organizational infrastructure to be able to pull off such an event, and manage a big chunk of the work that goes into organizing. We also provide a “parachute sponsorship”, patching up any holes in the budget that may arise.
