I led a technology team of 6, designed and built a scalable, high throughput infrastructure involving web, app, db, and messaging servers hosted on Amazon EC2, and created applications in python, C#, and javascript while overseeing the creation of applications in python, javascript, and ColdFusion. Some of the more impressive items I created at VoterTide/Beyond Measure LLC include:* Storage systems supporting real time answers to highly varied, complex queries over huge volumes of data (billions of transactions and terabytes of data)* Processes that allow on the fly modification to the filtering, tagging, and classification of incoming data by non-technical staff* Integrations with third party services such as DataSift with their own unique expert languages* Advanced Message Queuing Protocol based pipeline of data input, processing, and storage which allows for: * Easy scaling (simply by starting more consumer machines/processes) * Cross-language integrations * Rapid and accurate testing (through isolation of process responsibilities) * Simple feature roll outs * High up-time (even after critical failures or during maintenance/roll-outs, durable message queues resulted in no data loss and only minor lag for those users looking to query extremely current information)* Highly asynchronous systems to take in data from an enormous volume of HTTP requests (crawling).* REST-ful Apache web services* Responsive support for applications with high numbers of concurrent users to dynamic web services through the use of Amazon Cloudfront

* Pioneered the addition of optimistic and pessimistic concurrency in an application with many forms of data access to the same objects and a domain with wide ranging side effects on many of the objects.* Eliminated several legacy projects from a large (46+ projects) solution using complex regular expressions and custom tools to quickly resolve source code issues* Improved speed, reliability, and flexibility of automated builds by remaking the automated build process* Ensured protection of intellectual property and application security by implementing obfuscation in our products* Improved usability and performance while adding valuable features to key areas after taking ownership* Improved maintainability and speed of coding for other engineers by giving presentations and code reviews, writing dynamic and highly reusable view models for Windows Presentation Framework development and functional coding, and provided mentoring in the areas of object design, UI design, WPF layout and animations, and functional programming* Day to day duties were to design, implement, and review business and technical features in a rewrite of our primary software product.
