Summary: As a software development generalist with broad industry experience, I am probably best utilized in a senior/principal engineer or architect role. I have significant experience building and launching products from the ground up, and I have had primary responsibilities across the software development spectrum, including system architecture, backend, frontend, devops, and developer relations.

Cloud platforms: I have an intimate understanding of cloud platforms, having worked professionally as both consumer and provider. My current role is Ruby engineering lead for Google Cloud Platform, where I lead the team building Ruby libraries and SDKs, and serve as the primary Ruby technical consultant across the cloud organization, ensuring Ruby support for a wide variety of infrastructure, serverless, observability, databases, machine learning, and devops products.

Ruby and Elixir specialist: I'm active in the Ruby and Elixir programming language communities, a blogger, open source maintainer, and frequent speaker at major conferences. In addition to my current role as an internal Ruby expert at Google, I'm directly involved with maintaining a variety of open source projects including events, telemetry, serverless, and developer tooling.

Online application development: I spent seven years as the chief architect of a startup, developing web and mobile applications using Ruby on Rails and related technologies, including MySQL, PostgreSQL, MongoDB, Redis, Nginx, HAProxy, SASS, jQuery, Bootstrap, AngularJS, and so forth. I built and launched a number of products end-to-end and have experience with every aspect of the process, including data and application architecture, testing, deployment, security, scaling, and support.

Location technologies: I'm an innovator in geospatial/location technology for the Ruby On Rails community, the original author of RGeo, the most widely used geospatial data stack for Ruby, along with its integrations with GEOS, PostGIS, GeoJSON, and other common geospatial systems. My RailsConf 2012 presentation and accompanying blog series are considered foundational resources for geospatial technology in the Rails community.

Open Source: I believe strongly in the technical and economic vitality of open source. I am active in the open source development community, both as a primary developer and as a contributor to open source projects in a variety of disciplines.


CloudEvents Ruby SDK: The official Ruby reference implementation of the emerging CNCF CloudEvents standard. Browse source at https://github.com/cloudevents/sdk-ruby. I implemented and currently maintain this library as a member of the community.

Functions Framework for Ruby: The Ruby implementation of the Functions Framework, which underlies the Google Cloud Functions serverless hosting product. Browse source at https://github.com/GoogleCloudPlatform/functions-framework-ruby. I implemented and maintain this library as part of my current position at Google.

Toys: A configurable command line tool with a Ruby-based DSL and automatic argument parsing, error handling and online help. Browse source at https://github.com/dazuma/toys. This is a personal project under active development.

Ruby runtime for Google App Engine: A set of Docker images and build tools that form the infrastructure for running Ruby applications in the Google App Engine Flexible Environment. Browse source at https://github.com/GoogleCloudPlatform/ruby-docker. I implemented and maintain this system as part of my current position at Google. I'm also the developer of a similar runtime for the Elixir language; see the source at https://github.com/GoogleCloudPlatform/elixir-runtime.

RGeo: An open-source library for representing geospatial data in the Ruby language. Implements the OGC Simple Feature Access specification. Browse source at https://github.com/rgeo/rgeo. See also https://github.com/rgeo for a number of extensions and related projects. I was the initial designer and developer of these projects, and later handed day-to-day maintenance over to others in the community.
