A continuously-evolving, rock-star, senior software engineer from the front-end to the back-end with customer focus. In this industry, I truly believe you're either growing, or you're left behind. At present, I'm mostly focused on the design and development of web sites and mobile apps with Angular 18, Angular Material and Ionic 8 on the front-end. For the back-end, I'm up to date with Node.js, Golang or Java. MongoDB or MySQL are my preferences for the database layer. My philosophies are: 1) Make it easy to use and 2) Do what's right for the customer.

Bachelor of Science, Computer Science, Colorado State University. I have long been passionate with software and game development, and spent many years learning web development on my own time. I can mock up a website in just a day, and have excellent graphical and writing skills, allowing me to design software and websites efficiently. I am currently working on my own original game with Unreal Engine, modeling assets in Blender. I also develop plugins for a Minecraft server, which will become public in the future. I am looking for work related to my interests only, so that I can provide quality results, gain more experience in the job environment, and have something tangible to show off to future employers. So, I am not interested in touching up a wordpress website or other small things that can be done in an afternoon.
