Summary: As a software development generalist with broad industry experience, I am probably best utilized in a senior engineer or senior 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, and devops.

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, Twitter 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.

Cloud platforms: I have an intimate understanding of cloud platforms, having worked professionally as both consumer and provider. As a web and mobile developer, I have extensive experience with deploying with Amazon Web Services. My current role involves work on Google's cloud platform technologies, including App Engine, Compute Engine, and the various cloud APIs and SDKs, as well as cloud-based development, build, and deployment tools.

Location technologies: I am one of the leaders in geospatial/location technology for the Ruby On Rails community. I authored and currently maintain 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.
