    07/2014 to 03/2017
    Co-Founder and CTO TurboFlix (Turbo VPN Inc.) Burlington, Ontario

    Designed iterative Prototypes to match the fast evolving and challenging VPN Streaming market. The project relies heavily on proprietary solutions hosted on Amazon AWS, Rackspace Managed Solutions and Digital Ocean. Several server components such as BIND, HAProxy, Anycast and high performance VPN software are all used with several customization's for performance. The client-side was designed on a Raspberry PI and a breadboard which we had designed into a compact PCB board running a Broadcom chip and packaged in a slick black case. When we entered the market, we had 2,500 competitors, we quickly moved to be one of the top 5 solutions eventually becoming the first. In the last year we have watched competing companies close as they could not adapt to the new technologies required. In the first year we grew to 250,000 customers, eventually operating a client base of 800,000 at the end of 2016.

    01/2011 to 11/2013
    Founder Vault of Satoshi (Global Crypto Currency Inc) Brantford, Ontario

    Securing $250,000 from a robust prototype and the popularity of Bitcoin, we quickly moved to the top of the Canadian Bitcoin Market and were able to raise another $500,000. Customizing the block-chain software to run under server level conditions as well as securing the software to operate were required off the start. Planning ahead with these requirements allowed us to easily apply and pass the application and certification for becoming Canada's first Bitcoin Exchange operating under a Canadian Money Services Business License. After integrating with Equifax we were able to secure a deal to operate under a Schedule A Bank License allowing us to issue Debit Cards and Credit cards branded as our own. At the peak of operations we were responsible for safe guarding over 5 Million Dollars CDN, and over 7 Million Dollars in Bitcoin Holdings.

    10/2010 to 11/2013
    Founder, and Entrepreneur in Residence at Oracle Verelo Inc (Acquired by Oracle) Manchester, New Hampshire
    Let down by Pingdom several times, my goal was to create a robust Web Site monitoring solution that was easy to implement and up to the current standards of the Web. I designed the entire back-end, as well as the website and the core monitoring solutions. Monitoring 2,400 web properties per minute required a rewrite of our monitoring daemons, all which converted from Java to C. We successfully raised $50,000 pitching our solution to Extreme Start-ups, shortly after we opened up an office at 69 Young Street, Downtown Toronto. We were acquired by Oracle (Dyn) Shortly after a presentation.

This was an open contract, but I lead a team of eight Software Engineers under a tight and seemingly impossible deadline to victory, as we solved the underlying issues with several software redesigns and a migration to Amazon AWS. This lead to the successful acquisition of the Company.

    01/2011 to 06/2012
    Director of Research & Development Syncapse Senior Software Engineer

    The highlight of my career at Syncapse was saving a multi-million dollar marketing campaign by Anheuser-Busch on a weekend, hours before the Advertisements were to go live for Superbowl XLV. Shortly after I was tasked with ensuring our platform would passing quarterly PCI/DSS and routine security tests that were requested by Coca-Cola and Anheuser-Busch (our two biggest clients). Constantly experimented with several Cloud Solution Providers including Amazon AWS, Rackspace Cloud, Linode and several others. Having some of the largest companies in the world caused so many unexpected performance problems as well as many other computing challenges, I often worked hands on with the engineering team to ensure my experience was utilized as well as to teach our engineers some new skills.

    04/2010 to 01/2011
    Team Lead, Senior Software Engineer Hostopia Inc. (Deluxe Corporation) Toronto, Ontario
    Responsible for medium size team of developers, I lead a team to redesign the Fax-2-Email Product and migrate the customer base from an old ASP.Net solution to a PHP LAMP design with the back-end running fast C++ daemons. This fixed many choke points, and we signed a deal with Rogers @Home shortly after to take on their Fax-2-Email customer base. We were one of the first Companies to launch Fax over IP (T.38) in a corporate environment and drastically reduced our costs by eliminating the need for ISDN SIP trunks.
