Summary: I am a software generalist with broad industry experience. My master's research focused on various computer graphics topics such as image-based rendering, multiresolution geometry, and 3D photography. However, I have worked in numerous areas in industry, including client-server architecture, cross-platform development, web development, geospatial technologies, rich graphical clients, visualization, compilers, programming language design, collective intelligence, and more. I am probably best utilized in a senior engineer or senior architect role.
Languages/Technologies: I have experience with a variety of programming languages: principally Ruby, Javascript, Java, and C++, but also including Python, Perl, Lisp and related dialects, and several others. My most recent work has been in Ruby, including web development using the Ruby On Rails framework, as well as development of numerous libraries and integrative systems for tasks ranging from content management to data mining to system monitoring. I've even contributed to both the Ruby and Rails core development. I have also done client-side Javascript work using jQuery; a considerable amount of relational database design using PostgreSQL and MySQL; integration with Apache, Nginx, Tomcat, and other containers; geospatial work using GEOS, Proj4, PostGIS, and other systems; and many, many others.
Library/API Design: I have extensive experience and a particular interest in library, API, and framework design. As part of my current work I have produced a large, integrated suite of components and extensions for rapid development and deployment of Ruby On Rails based web sites and services, with a special emphasis on geospatial database and spatial analysis technologies. A small portion of this work has been open sourced as noted below. Previously, I produced a number of frameworks and libraries in C++ and Java, including GUI widget libraries and GUI frameworks, a distributed service manager and software update system, 3D geometry templates, and many others.
Web/Internet Technologies: I have extensive experience with scalable web development techniques and technologies. Having done engineering work for Internet retail giant Amazon.com, I understand scalability and large-scale web architecture concerns; and as chief architect for an Internet startup, I have experience with end-to-end implementation of an Internet strategy, including application development, data modeling, web service architectures, deployment, security, performance monitoring, and agile processes.
Platforms: I have experience with the Mac OS X and Linux (primarily RedHat-based) platforms, in both software development and system administration capacities. I also have a high level of familiarity with unix-based and open-source tools and technologies such as subversion, gcc, ruby, postfix, apache, and many, many more. I prefer not to work on the MS Windows platform.
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.
