Flex Developer for visual analytical tool

Olga quickly apprehended the underlying architecture of the product (which was not well documented), quickly fixed bugs from earlier work, and then proceeded to implement new features in an elegant and efficient manner.Olga understands the many subtleties associated with complex AS3 projects, makes excellent suggestions on how to improve a design, and performs her work in a timely manner.I look forward to hiring Olga again on future projects.”
