I am a software engineer with experience in technical leadership, full-stack development, systems engineering, and community stewardship.
As a technical leader, I provide strategic and operational leadership to organizations and teams by building and communicating competitive engineering visions and guiding the cultivation and growth of individuals' careers.
As a systems engineer, I design and document large-scale software architectures and business communications architectures. My preferred architectural patterns include event sourcing and CQRS, service-oriented architecture (SOA), and microservices. I utilize architecture tools and frameworks including UML, DoDAF, GraphViz, and System Architect.
As a community steward, I organize programming events and study groups, lead programming lectures and workshops, and maintain open source software projects. I utilize collaborative tools including GitHub, GitLab, Bitbucket, Travis CI, CircleCI, and Jenkins.
Some of my favorite talks include hands-on category theory, functional refactoring, and discovering knowledge in linked data.
Some of my favorite open source projects include xsbt-web-plugin, codedown, and swagger-test.
