Professional Software Development for over 30 years
Hi, I’m Nathan Gopen, freelance software developer, multimedia producer, and owner of Diadem Productions.
I’m an MIT graduate, and I’ve been writing computer
software both as a hobby since age 12, and professionally for all of my adult life. I’m a full-stack developer with many years of desktop, multimedia, web and mobile experience, and can solve any technical or creative challenge that comes my way.
I’m also an entrepreneur and business owner, and I’ve been on your side of the table more times than I can count. You’re looking for a freelancer who can understand your vision, take the initiative and think through solutions and creative concepts that you may have overlooked, and deliver results on time and within budget.
I’ve spent over 20 years working with direct and contract jobs for Fortune 500 companies, as well as many years freelancing for creative agencies or direct clients. I know how to stay organized, communicate well, stay on top of a project and get it done.
Don’t waste time and money on bottom of the barrel overseas programmers who always get it wrong, or junior programmers who just don’t have the know-how – only to have to come back here six months later and thousands of dollars poorer. Get it done right and well the first time. Let’s set up a phone call to discuss your project in detail. I look forward to gaining your trust and helping you achieve your vision.
