"Everyone has a plan until they get punched in the mouth."
Thanks for visiting my website. It is a mix of personal interests and professional experience.
My professional background is focused on software quality assurance, but not just pointing and clicking! My approach to quality assurance is engineering based with an emphasis on "pushing left" and building teams from the "ground up". This means understanding the importance of being involved early in the software development lifecycle, being able to create detailed documentation, reliable processes, automating error-prone, mission critical and mundane tests, as well as harnessing human strengths (like exploratory testing).
I also have speaking experience on a variety of topics software quality assurance-related. My contact information is in the footer if you are interested in having me speak at an event.
When I'm not being a software quality assurance guru I enjoy a variety of activities, some of which are represented on my website. I like making craft cocktails , building things , and listening to podcasts.

Curious Cometary Knots in the Helix Nebula
What causes unusual knots of gas and dust in planetary nebulas? Seen also in the Ring Nebula, the Dumbbell Nebula and NGC 2392, the knots' existence was not initially predicted, and their origins are still not well understood. Pictured here is a fascinating image of part of the Helix Nebula by the James Webb Space Telescope showing tremendous detail in infrared light. The cometary knots have masses similar to the Earth but have sizes typically several times the orbit of Pluto. One hypothesis for the fragmentation and evolution of the knots includes existing gas being driven out by a less dense but highly energetic stellar wind of the central evolving star. The Helix Nebula is one of the closest examples of a planetary nebula created at the end of the life of a Sun-like star. Given a technical designation of NGC 7293, the Helix Nebula lies about 650 light-years away towards the constellation of Water Carrier (Aquarius).
