Although you see me new on freelancer.com. I am a full-time industrial design freelancer, have 8 yrs design experience, graduated from Pratt Institute, US. I am a full time freelancer now.
I have bid for a fix price, however, there is no much description on your board, so the freelancer cost can be negotiable after we get into detail.
For my Maths ability, I like to highlight my project on sphere dog house (in my portfolio review). It is about a 4 feet sphere house that constructed by wood. When you see this portfolio, on the right side is all my little calculation for individual wood piece, that I have an ability to figure out complex dimension for all components in product. I do same thing for casino signage (the exploded view on my portfolio page.)
Solidworks have been my 3D tool for all my 3D modeling, I have no problem with this software.
Now as freelance design, I can finish the job sooner for you.
I always communicate with my client via whatsapp, in additional to email. This I find I can have quick respond to client. You are also free feel to contact me via whatsapp, but I don't limit it with email as well.
Please feel free to question me, and review my portfolio samples.
