Also extracted data rows for the report generator using using customized pseudo-SQL queries, all using Python.
Also serving in a community leadership position for the engineering team, providing support, guidance, and encouragement, trying to bring some stability to a hectic startup environment. I advocate agile development, longer, more well-thoughtout design processes, and careful architecting vs. hacking systems together that are thrown away later. Helped organize the company's presence at the PyCon conference and generally make myself available as an in-house Python resource. Also have been writing up a "PyTips" column for the team giving insight, describing useful modules, suggested tools, and best practices.

Senior Engineer: Building applications for optimizing localized retail shopping for consumers who research and shop online but prefer to buy offline. Built an SMS/text messaging service allowing mobile phone users to utilize the company's search engine to find products, sales, coupons, brands, etc., at shopping malls and have results delivered directly to their cell phones which interfaced to the mBlox mobile transaction network (via XML). Also developed an in-house application to help CSRs manage product reservations and availability checks for customers. This customer reservation tool was built on top of RoundUp, a relatively simple yet highly customizable Python issue tracking system. Responsible for system maintenance product requirements such as deployment and release, monitoring, log management, and reporting. Work performed on CentOS Linux, Mac OS X, and Win32 systems using Python as the primary development tool mixed with writing Unix shell scripts and MySQL queries. Parsed some XML and JSON using various tools as well as SQLAlchemy and Elixir for higher-level ORM database access.
Software Engineer: Designed and architected computer applications for a series of electronic mail security gateway appliances used for high-performance message delivery and spam and virus filtering services. Development performed using (both native and coroutine-based stackless versions of) Python in FreeBSD Unix, MacOS X, and Win32 operating environments with the MySQL and PostgreSQL database systems. Specific products worked on include: Virus Outbreak Filters® (temporarily quarantine suspicious messages during the vulnerable period between time zero -- when a virus is released into the wild -- and when an antivirus IDE signature is made available to the public), Mail Flow Central® (message tracking, appliance data import and analysis, report generation, etc.), Spam Quarantine (message view and search), and Threat Operations Center application code which helps operations analysts monitor for worldwide viral outbreaks.
Senior Software Developer: Lead software engineer for clinical trials medical imaging application which allows radiologists and trained technicians to perform vertebral identification in a digital domain, quantitative morphometry (QM) reading, and both semi-quantitative (SQ) and binary semi-quantitative (BSQ) scoring of spine radiographs (X-rays) for vertebral fracture analysis and assessment. Enhancing and developing software in a Unix/Solaris environment using Python, Tk (Tkinter and Pmw), and C, and database queries and stored procedures using Sybase Transact SQL.
Technical Yahoo!: Lead software engineer managing one junior engineer for Yahoo! People Search, an online email, telephone, and netphone database directory (replacing the original Four11.com site) -- proprietary database with SQL-like access.
