Welcome on Beyama

Hi! My name is Alexander and I am a freelance developer focused on Ruby on Rails, node.js and Android development. I've also a background as Linux server administrator.

Below is a short summary of what I can do to help you and how I work.

Service

I cover the classical development spectrum ranging from planning, implementation, testing, documenting to deployment and maintenance.
I offer development services preferably utilizing Ruby/Ruby on Rails and JavaScript, as well as CSS3 styling.

Additionally, I offer conceptual work for personalized hosting infrastructures to suit your needs.
This includes optimisation of existing solutions.

Principles

I work iteratively, according to the principles of agile development. I do not work on fixed-scope, fixed-cost projects.
I prefer to work from my home office. I'm not looking for full-time on-site work.
