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.
