Technologies to Leverage

Opensource SaaS

I personally believe in flexing opensource projects, especially when they're this robust, it would save a lot of development time and provide a flexible framework for easy tweaks in the future. Using a framework like the above would provide an environment that cards provides where no code, GUI edits and functions and be changed on the fly. Additionally we can just fork any of these projects to make deeper tweaks as needed.
