Hi, Matt S Rinc here and I can help you - 20 years of software development, now more and more in statistics (3 years or R) while of course a multimedia pro, graduated with image recognition.
Please expand more what type of D3.js projects you plan to see if I can match them. I don't have portfolio of them yet but I will in the future - and work until it's done.
Without further details the bid amount is my daily rate (8-10 hours).
Looking forward to your reply,
Matt
