Hello!
If you have a specific question about any of the open source repositories that I contribute to, the best way to ask is to open an issue on the repository itself.
If you have a more general question about using ArcGIS maps and/or services in JavaScript applications, the best place to ask is on GeoNet, GIS StackExchange, or StackOverflow with the appropriate tags and cc me (@tomwayson) if you would like me to respond.
You can also find me (@tomwayson) involved in the discussion about those same topics on twitter.
I’m not currently in the market for a job. I love working for Esri, but if you think you might like to join us or are looking to network, you can reach me on LinkedIn.
I look forward to hearing from you.
