    70% of all software projects fail. Why is that happening? A few reasons: - Poor communication - Poor communication - Poor communication - Badly defined requirements - Wrong project's priorities - Sloppy development practices How do I address these issues: *Communication & Requirements clarification* - Monday to Friday daily status meetings at fixed time, suitable for all team members(customer is a team member). - Weekly iteration planning meetings. - Transparent and easy-to-use Project Management tools. *Project prioritization* - Complexity estimation - Short iterations & short feedback loop *Development practices* - Perfectly clean code - Test Driven Development (99% test coverage). - Obligatory code review & collective code ownership. - Domain Driven Design, Lean Architecture, GRASP, SOLID If this sounds good for you, let's get this done.

    I am a college student who is very much still learning the trade, but I am fully capable of creating functioning Java, JavaScript, jQuery, HTML, CSS, Ruby, and Python code. I like to think of myself as a perfectionist, so I usually end up taking as much time as possible to make each sure each project is of a high quality. I am still studying, and I am learning new things all the time, so please feel free to provide me with a challenge!
