Building better digital worlds.

lambdaforge is a consulting company that specializes in information system engineering and digital products.

We design and build scalable, maintainable and reliable systems for data-intensive applications by building on a combination of the best open-source industry standards and our own open-sourced stack.

Our speciality are functional programming paradigms to deliver high-quality products in quick iterations. We can beat the averages by minimizing the complexity of our solutions with Clojure and JavaScript.

We are not only able to handle large amounts of data in our pipelines, but believe in tight integration with both well established and bleeding-edge data science technologies. To do so we conduct scientific research parallel to our consulting work.

We can work with state-of-the-art machine learning frameworks in Python or R, but through our deep understanding we also tightly integrate the necessary numerical routines directly and can infer business-critical information in realtime.

About us

Given a problem our team of specialists forms a self-managed, focused unit formalizing the product design given the underlying business model to implementing a flexible scalable full-stack system design. We then keep your long-term costs low by running the resulting system smoothly.

Work with us!

Wade Dominic

Wade Dominic

Jack of all trades

Wade dances on the border of creativity and logic. As a designer developer he establishes channels of communication which visualise and articulate a vision right through to the implementation details. His unique experience and perspective streamlines product development by avoiding miscommunication and wasted/throwaway feature development.

Always on the pursuit of more knowledge he now studies mathematics and physics in Australia.

Ferdinand Kühne

Ferdinand Kühne

Open Source Contributor

As an avid open source developer Ferdi supports us in his free time on our open source libraries konserve and incognito. He works at jSERVICE as a Clojure developer in Münster.


As open source developers we are interested in transferring our knowledge about our work as often as possible. Here we are collecting the latest blog posts, screencasts or announcements.

Got some questions we should write about? Let us know!

Title An Introduction to the Hitchhiker Tree
Description The goal of the Hitchhiker tree is to wed three things: the query performance of a B+ tree, the write performance of an append-only log, and convenience of a functional, persistent data structure.
Title Rapid Web App Prototyping with Clojurescript
Description A short trip through web development via Om, a beautiful React-wrapper in Clojurescript, and replikativ, a simple synchronisation infrastructure


Having worked with large corprations as well as small startups, we are able to adjust to different environments.

We are happy to help you with your digital challenges!
