    PHP/Java Developer for Custom BrainTree Invoice Payment Portal
    Supun was an outstanding contractor. His skills were perfectly suited, and when he had to adapt programming languages mid-project to work with my evolving implementation schema he didn't miss a beat. Great communication throughout and a genuinely nice guy. The next time I need a developer I'll call on him for sure.
