I've been working with Matlab since undergraduate level, and website development is a passion for me. I am fluent in Matlab and a few backend web frameworks such as PHP, Python, etc.
You have not given much description so I won't be able to explain how I will approach your problem, but if it's ranking somewhere around transmitting data between Matlab and a web database I assure you that can be done quickly. If that's not it, then I would like to enjoy working with you on other problems.
Do give me a chance, and you won't be back at Freelancer anymore for these kind of jobs.
