• Atomist creates development automation tools, including CI/CD; checking and changing code across hundreds of repositories; and responding to events and chat commands.
• It is a new sector in developer tools, creating new possibilities, new levels of automating our own work in order to scale software development. At conferences and through blogs, I worked to create this sector in the market, teaching and inspiring developers to think bigger about what we do.
• I helped with the core libraries (originally in Scala, now TypeScript running on Node.js). I wrote a good bit of documentation (github.com/atomist/docs), including taking charge of delivery automation for the docs (github.com/atomist/docs-sdm). I made the developer-facing GUI for github.com/atomist/org-visualizer, which seeks and displays information across repositories across GitHub or on your computer.
• My particular focus is to make it easier for developers to understand and use the tools.

• Development in Clojure, on a fully remote team with a culture of pairing and deep collaboration. We built and maintained a system for demographic-targeted ad display, which observed behavior of customers shown ads and fed that back into targeting strategy. We used Ansible to deploy Clojure web services in AWS, and processed events in ElasticSearch and Hadoop. Our team coordinated very well with Zoom, Slack, and Trello. At Outpace, I learned that fully remote teams can have great communication and rapport.
