I am a software engineer with experience in technical and executive leadership, full-stack development, functional programming, systems engineering, development operations, and community stewardship.
As a leader, I provide strategic and operational direction to organizations and teams by building and communicating competitive engineering visions and guiding the cultivation and growth of individuals' careers.
As an engineer, I design 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.
I like to give talks on things I find interesting and challenging. Some of my favorites include Hands-On Category Theory, Functional Refactoring, and Discovering Knowledge in Linked Data.
I like to build and maintain open source projects. Some of my favorites include xsbt-web-plugin, codedown, and swagger-test.
