  • I've been writing software for a few decades and I (still) love it. Over the years I've played with mainly Big Data, full-stack web apps, multi-threaded (near) real-time server apps, and embedded software.
  • At the day job, I'm working with Kubernetes, Podman, Spark, MapR (now HPE Ezmeral), and Hadoop in general.
  • Previously I was doing web dev with D3.js, C3.js, Node.js, Express.js, Python,, MySQL, Apache httpd. For many years prior to that I programmed almost exclusively in C++ (some C++11, some Boost) and Perl (I much prefer Python now).
  • I've dabbled with Go, R, Java, Google AppEngine, AWS, GraphViz, IBM Streams/SPL and BigInsights, Oracle OEP, DynamoDB, Ionic. I've read books about Google Compute Engine, Heroku, Neo4j, Redis, and MongoDB, and I've taken a few Udacity iOS courses , but I never got around to actually trying any of these out on any projects (bummer, eh?).
  • I created an online Angular course at, with an emphasis on Observables, Change Detection, Dependency Injection, Data Binding, and Inter-Component Communication and Data Flow. Too bad the course is no longer up to date. I learned that creating a good course takes too much time and effort.
  • Current interests/learning: Kubernetes, Podman, Spark, Elasticsearch, Python, pipx
  • First computer: Commodore64 (I still have one)
  • SO badge I'm most proud of: Sportsmanship
  • My profile picture: my son gave me that lego minifig years ago, but I put the Angular logo on it
