Application and Website Development

Since 1982, Leszynski Group's application design and development team has built hundreds of custom solutions and websites for our clients in a broad variety of industries. In fact, our code is run by hundreds of millions of computer users around the world every day!

Our team of solution architects and C, C#, Java, and SQL development experts eagerly tackles software development challenges that might intimidate less-experienced technicians. That's why Microsoft chose us to help design and develop Windows Holographic and the new HoloLens technology. See our skills listing here.
