Ruby, Rails, Vue, React, Node, GraphQL, Cordova, Expo, Storybook, Postgresql, Redis, ElasticSearch, AWS, Heroku, CI, bla bla bla

* React and Vue! both are really solid technologies that have revolutionized front-end development in a really positive manner.
* Cypress! I've been a selenium/capybara/cucumber fan for a... long time... This next gen end-to-end-testing library is pretty dope.
* GraphQL! Initially I was pretty put off by it, and still believe it's a more awkward system than traditional REST; but leveraging it as a tool for eventually consistent distributed data has been fantastic.

Most of my time is focused on client work at the moment; but I do maintain a small set of useful workflow-oriented tools:

* Informed, which makes instrumenting your application with structured logging statements easy-peasy - https://github.com/wecohere/informed
* Coruro, which provides process-management and stubbable/spyabe fake-services like email, stripe, firebase, etc. - https://github.com/wecohere/coruro

* Technical coaching on node, ruby, rails, continuous integration, infrastructure management, or software testing.
* Delivery, with a minimum budget of $20K/mo.
* Team training on pair programming, refactoring, testing, software design, hiring and interviewing, and other such topics..
