Lead Infrastructure team. We made shit not so shitty.I came in through acquisition of Massive Health and built the team from the ground up, which eventually absorbed the Operations team, which was originally a part of the IT department.We turned a brittle, monolithic, old-school application with a small number of users into a fully-modern, automated (deployment, configuration and testing), SOA system that scaled to big numbers (users and computers). The huge architectural changes we made were responsible for Jawbone's increased uptime, and hilariously, lead to the first Christmas morning without any service disruption. Turns out everyone turns on their shiny new electronic gifts at the same time, which leads to interesting traffic burst scenarios that are difficult to test.Helped architect and build a system for computing real-time, streaming aggregations which is now the backbone of most of UP's smart content, personalized data analysis, and trends features.

Development and maintenance for our kinda popular app called The Eatery. It's not available anymore, but we got some really cool data out of it.http://data.massivehealth.com/R&D for our next product, which was never announced but was continued when we were acquired by Jawbone.

Making Formspring scale for fewer $$$.

I worked on pretty much everything during my tenure at Linden Lab, both client and server side. Here are some example contributions:* Optimization of the object and geometry pipeline.* Performance and scaling work across the board, on both the client and server. Optimizing C++, Python and PHP code, proprietary network protocols, and melting MySQL databases.* Maintenance of LSL, the scripting system for Second Life, as well contributing to the initial support of C#.* Maintenance and enhancements for third party libraries, such as Mono, Greenlet, Eventlet and Mulib.* Python bindings for Kakadu, the JPEG2000 library for C++.* Second Life Enterprise* Server side baked avatar texture pipeline.* I wrote the auto-updater for the Linux port of the client software.* Debian packaging and software for system imaging and deployment.* General release engineering.

We are developing a courseware management system called LOCUS, which is similar to moddle, blackboard and webct. It is currently used by about 90 classes at the University. It was developed in PHP using the MySQL database. We will eventually release it as free software.Duties included profiling existing applications and modifying them to improve performance and scalability, and re-designing some portions of the site to improve accessibility.

Developing an Information Security Management System based on OSSIM (http://www.ossim.net). Correlating data from Snort IDS, switch and router logs, and log information from 300+ servers in a centeral database where it can be anylized in real time.
