Open Source Development, Open source is a development methodology, which offers practical or total accessibility to a products source code.
As my own point of view it is the most secure and honest method of development, it is completely open, so its also visible to other developers and people in general to look at it and inspect it for errors and bugs.
We as a high-end web development firm, that supports Open Source Web Development 100%, are dedicated to create all our application developments, shopping carts, ecommerce services, administration platforms and other services using open source technologies, services and programs.
