We have two web apps that require code review and UI testing. The UX is basically a UI dataviz--let us know what this means to you.

Our Criteria for the Ideal Expert

Experience testing the user interface (PHP and D3.js) for a software product where the user clicks on elements of the user experience and triggers changes to data visualization that is the UI. An emphasis on detail exploring features for selecting things like buttons and areas of the screen Must have experience testing across browsers including working iOS and Android using native apps and mobile sites Because the dataviz changes based on the data you will need to provide a test plan and execute it across different data sets that you will load as well as all browsers and native apps including mobile sites. Ability to log detail in a bug tracking system or video recording so that we can see the problem Agile

Please share your experience building test plans and testing UIs across browsers and platforms. How good are you at PHP and D3.js to be able to do code review? Would you use any specific tools?

You must answer all questions and provide your approach to be considered.
