Software Architecture and Development

I have expertise in architecting and developing software from top to bottom, from the user experience through data storage and retrieval and everything in between. I embrace the development process from analysis at 10,000 feet through well-written lines of code.

I have expertise in cloud services, particularly Microsoft Azure and AWS. I love web application development and UI/UX, including chat bot development with platforms like the Bot Framework.

Nonprofits and Education

I helped start up The Physics Factory nonprofit, a science education organization dedicated to inspiring interest and learning through outreach and mentoring. Originally founded in Tucson, AZ, the Physics Factory has recently expanded with a Physics Bus program in Ithaca, NY.

I love absorbing languages and cultures, and getting to know people from all over the world. Work and pleasure have taken me to over a dozen countries in five continents so far. It's a lifetime journey.

Hablo español. Je parle un peu le français. Eu falo português, mais ou menos.
