We do have since some weeks a major java based software development project ongoing with freelancers involved around the world.
For QA analysis, quality reporting on code, module and setup we do need a highly qualified, experienced QA .
You should know Java with all tools like Spring, db like mysql in and out and you have supervised projects. Architecture - you should tell us what we can improve.
Of advantage would be if you have made experience with booking engines,in hotel, airline, toursim or event.
