Profile bio
About John Mcguinness
I'm a .NET developer who likes to work on the full-stack. From front-end UI, to back-end database development, and everything in between. Recently, I've been getting into mobile development using Xamarin to create iOS and Android apps using a shared core library.One of my greatest strengths is saying yes when other developers say no. For me, there is always a solution, a way to accomplish a task. “No” to me is a challenge. When working remotely, as I do, good communication is key success. I ask pertinent questions and I’m not afraid to ask something if I don’t have solid direction.
