About us

Our experience and past work are the best way to describe us.

From early 2017, we worked in many IT fields and sectors. Most of our work and experience is from the cryptocurrency space. We are working with Haskell for blockchains and consult for Haskell web applications. We are working with Purescript, Angular, React, Elm and Reflex for web frontends.

We created a lot of AI-based products ourselves written in Java and Python. Python for AI-based components and Java for web applications.

Our work is based on two principles:

Make it work, then optimize.

Keep it simple. Keep it clean.
