About

I am a Software Executive based out of Greater Boston. Taught myself to code and started writing software when I was 13, since then I have shipped software on several platforms over the past 25 years. Currently interested in machine learning, high performance web apps, mobile, security, network architecture, electronics and robotics.

A few years ago I wrote a Programmer Competency Matrix which has been popular. In 2012, I took part in a NFC/Android Hackathon and was ranked #3 for my app LokoChat which lets you create HyperLocal chat rooms. I made my first open source contribution in 2011 to Python and more specifically CPython. I was a Most Valuable Professional (MVP) for Microsoft in 2005 for my contributions to the .Net and C# community. Recently I’ve been advising HackerRank as part of their Skills Advisory Council.

I’ve been developing software professionally for more than 17 years now, the majority of my experience has been in working with startups, building and managing software teams, and shipping awesome software. My LinkedIn profile has more details.

I enjoy solving problems using code, learning new things, reading and writing about technology.

Spoon Application Virtualization Technology

Spoon uses proprietary app virtualization technology to allow streamed apps to execute instantly in an isolated environment on any Windows desktop. Unlike hardware virtualization solutions such as VMware and Virtual PC, which emulate the underlying hardware and therefore require an entire copy of the host operating system, Spoon app virtualization technology emulates operating system features required for execution.

Youthful Arrogance

In 2000 when I had just started my master's degree I had already been programming in C/C++ and VB for some years prior, mostly simple LoB apps for my dad's business and some other telecom programs that I had written while working as an intern during my undergrad years studying mathematics.
