About Me

I am an expert in front-end development and React/Redux or Angular 1.x. I also specialize in real-time web protocols including WebSockets, WebRTC, and interactive 2D and 3D graphics using Canvas and WebGL. I am passionate about programming and seeking out the most innovative and creative solutions for my clients. I am very detail oriented and consistently deliver the best and cleanest code possible.
I am very mindful of on-time delivery and consistently meet deadlines. I will work long extended hours to make any project successful and will not close out a project until the client is fully satisfied.
