Highcharts development and integration in WordPres
Amazing work ethic and deliverables. I can highly recommend and will definitely use again on future projects.
The project was complex and included data integration with HighCharts and DataTables. Sometimes you don't know what you don't know ahead of time and he always was willing to provide the best solutions without compromise.
Communication was outstanding! His prior experience and knowledge of the subject was obvious and this goes a long way when you're unsure about hiring the right person for the project.
Above and beyond is what he provided and I couldn't be happier with the result!
