    I've been making software on the web (mobile, too!) since age 10, first teaching myself Javascript, Visual Basic, PHP, & Objective-C... actively learning how to create things in harmony with technology. I wanted to bring the imagination into the physical world. So now, I build the stuff dreams :). I was a part of a team of hackers in the 90’s building out the next AOL Instant Messenger, developed/designed a massive $500+ million fintech live trading web app, architected a successful $100+ million real estate CRM platform for a startup, built live streaming services with drone integrations for the Pentagon, and have collaborated with some of the best minds in tech over the past decade. I'm a polyglot programmer, fluent in almost every programming language. I really enjoy every aspect of engineering systems. I've seen & worked with almost every environment you can think of, and written in pretty much everything except C/C#/C++. I began programming & selling websites as a teenager before a lot of modern day programming languages even existed. When I'm not spending time with software, you can find me oil painting in techniques developed by Italian Renaissance Masters, making digital crypto-artwork, and sharing some of my life and work through weekly newsletters & videos: an online series focused primarily on wellness, artwork, & business- highlighting what it's like to be a business owner, artist, developer, and wellness activist in today's digital world, while building community at it's core.

    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.

    As a curious kid, I had a desire to know how all things (especially gadgets) worked. When the iPhone was first released in 2007, I was determined. I began by jailbreaking to understand how iOS worked, and I started developing iOS applications soon after. So yes, I know what life was like before ARC :P In addition to freelance work, I've worked at a couple of startups, founded my own mobile application development company, and worked for a few larger corporations including Google. My experience of over ten years has helped me become proficient at mobile application development at a large scale.

    I’ve been writing software professionally since 2009. Most of my experience comes from building iOS apps, but over the last few years have been focusing more of my time on server-side development. That said, I still enjoy working in Swift. I maintain an open source iOS app (American Chronicle), and also a Mac toolbar app (Listen).
