Charper Bonaroo

We have worked on a wide range of software products over the years and acquired intimate knowledge on various languages, frameworks and tools. We feel comfortable with ‘the usual suspects’ of web-development such as Ruby and Ruby on Rails, JavaScript (and frameworks like VueJS and React) and PHP. More recently we have been charmed by the Elixir language and the Phoenix Framework for building applications and API’s.

To a lesser extent we have a working knowledge on languages like C/C++, Python, and Java and Swift for Android and iOS development.

Next to application development we have extensive DevOps experience. We keep our applications running efficiently with Docker, Kubernetes, Google App Engine, Heroku, AWS, Chef and Puppet. connects dairyfarmers and traders on a structured communications platform to facilitate trade and ease administrative hassle.
