About us


Started at the beginning of 2017, we worked in many fields. Mostly in the cryptocurrency space, we worked with Haskell on blockchain and did consult for Haskell web applications. On the web we worked with Purescript, Angular, React, Elm and Reflex.

We also created a lot of AI base products ourselves that use Java and Python. Python for AI-based components, Java for web applications.

About our work? We think any good work should be correct, it should be well specified and executed by that specification.

Don’t build something you don’t want. What you build should be well tested and precise. Doubt it will work, and you will find ways to improve it.

Make it work, then optimize.

Keep it simple. Keep it clean.
