"Wayne is not only skilled at directing a software product from an architectural standpoint, he also is able to understand it a micro level. As a result, he usually has a very complete grasp of any code he works with for any significant amount of time, whether it's something he's designed or something others have designed." -- Jim K "I experienced Wayne as a highly skilled and motivated software engineer, with a fast and analytical mind. His expertise and creativity always made him the default technical lead of the team. I highly recommend him." -- J. Ovesen With the right software engineer, your project can be done right the first time. When the strongest developers are 10x better than the weakest, working with someone with the lowest hourly could be more expensive than working with a strong engineer with a higher rate! I have been writing software for 30 years, from web, mobile, and desktop apps to firmware written in assembly. I understand software development at its core and can therefore handle your project expertly. In addition, I have been leading software development teams for 2 decades so I can help you manage a team if that is what you are looking for. On the mobile app side, I wrote the first few versions iOS and Android apps for Sound World Solutions, and internal tools in Xamarin and Swift. I also wrote and maintained an inventory management app that used barcode and RFID scanners in Xamarin. On the desktop side, I was the technical lead for the fitting software at GN Resound in the early 2000s. Recently, I have written factory test software and a lot of internal tools in C#/WPF. I have also written desktop software in Java for cross platform compatibility. On the firmware side, I have written the software on a hearing aid on 2 different chipsets and 2 different DSPs. These were written in C and assembly. For web apps, I have worked on e-commerce sites for Sound World Solutions and, too many moons ago, on J2EE and ASP. Currently, I am working on a project in Laravel. As you can see, I can help you with your project! I am efficient and deliver quality code. Please get in touch if you would like me to join your team.
