Design, create and ship it

Test Driven Development

Software without solit tests will be your darkest nightmare. I want to sleep well at night, that is why all the software I'm creating are driven by unit and integration tests.

Continous Deployment

I strongly believe in continous deployment, so minimizing the time between feature development, testing and pushing to the production is my goal.

Cloud Computing

During my work with Atmosphere cloud system I gained deep understanding of different cloud platforms, such as Open Stack, Amazon, Rackspace and Google Compute.

Whatever the mind of man can conceive and believe, it can achieve.
