- Wrote Dockermon - a Python monitoring / stat-collecting daemon for Docker that ships per-container metrics to Riemann and Graphite.
- Built and architected the Marathon / Mesos / Zookeeper fault-tolerant infrastructure. Maintained and monitored the infrastructure and performed many zero-downtime upgrades on the production environment using the blue / green deployment approach.
- Wrote commands and plugins for the internal developer CLI tool to simplify the development process. One of such tools, “stage-me”, provides a method for a developer to spin up an entire environment for an application with a single command (not unlike Heroku push).
- Rewrote all of the existing infrastructure cookbooks, stripping out cruft and decreasing the total system provisioning time from 40 minutes down to 5.
- Well-versed in configuration management software and source control (Chef, puppet, git, etc).
