Sir,
I've a master degree in embedded systems, and a java expert. I've worked on many algorithms and finished many complex projects.
Your project is simple, and I can do it easily within 2 days as soon as you grant me the job. What I will do is simple : you confirm me what are your needs, then I start developing easy code that is tested, commented and documented. I'll stay in touch with you during all the progress so that you can follow what is being done.
I'd be glad to work with you on this project, as I love developing in java, so I look forward to your response.
Regards
