For 10+ years, I was a web developer. What started out as Flash / Actionscript transitioned to full blown enterprise PHP and JavaScript and some machine learning and AI while working for Diffbot.com. That was until I noticed blockchain technology and completely switched over. I quit my full time job and dove into a 1 year learning-only spree. 4 years later, I am a blockchain and Solidity expert, producing and auditing smart contracts daily, writing dapps, speaking at conferences about blockchain's technical and regulatory updates, and writing technical tutorials at top rated sites like Bitfalls.com and SitePoint.com. The video attached is one such conference - the Blockchain Innovation Conference in Utrecht, NL. I am driven by the decentralized and censorship free promise of the web of tomorrow. It's the reclaiming of the internet that most excites me in the blockchain era, and I enjoy every moment I spend researching the ecosystem and coming up with new long term solutions for true digital freedom. In my opinion, the "currency" or this "cryptocurrency" fad is secondary in all this.

I am a geek, visionary, startup enthusiast, occasional tech blogger, software developer & entrepreneur and most of all a salesman. I am simply uninterested in mediocrity. I don’t settle for average. People say I have a mind that is always running--I'm just that guy who's guilty of staying up all night thinking about how I can be truly exceptional at what I do. You might call this a truly positive or competitive spirit, but I call it passion. I have cofounded that received +$1 million funding.
