I needed a solution to create 'with a single click' a PDF file containing both text and automatically generated financial charts based on a combination of HTML and JavaScript. Excellent delivery, on time, great communication along the way and very well documented. Highly recommend!

Was great working with Alexandra. Needed help to rewrite / optimize a code for charts generation in Javascript. Not a simple project, still good final result and great communication along the way. Will surely come back with additional projects.
