Software Architect

• Designed and developed common infrastructure for all Monkey Inferno projects: Jolitics is a new social political debate and issue voting web application. Zuno and Birthday Alarm are electronic greeting card services. Charity: Water and Help Jess Breathe are charities.
• Designed, configured and installed a Cassandra distributed storage clusters for Monkey Inferno data, in preparation for the petabyte scale image storage anticipated for Monkey Infero child companies.
• Designed and developed an image web server that scales, crops and caches images on demand for Jolitics and Zuno in Python with the Tornado web server using PyCassa and Cassandra for storage.
• Designed and developed a queue, batch job and listener event system using Python and Redis for asynchronous jobs in Jolitics and Zuno. The Redis queues fed the listeners and batch jobs. The system is used for scraping Facebook, greeting card delivery and recalculating Jolitics issue vote and member nomination pyramids.
• Designed and developed a vote and member nomination calculation algorithm for Jolitics in Python. Members of Jolitics can vote on individual issues and nominate each other to enable proxy voting. The issue vote and nomination pyramids require constant recalculation.
• Designed and developed an Email bounce parser and action system for Zuno and Birthday Alarm in Python. The system parses Power MTA logs and bounced mail to gather statistics about bounce and delivery rates. The system automatically re-sends email that soft bounces, removes address from our lists that hard bounce and alerts humans to MTAs that have blocked us as spam.
• Designed and developed an international identity authentication system for Jolitics using SMS in Python in compliance with the Clickatell callback regulations for obtaining a Clickatell shortcode.
• Designed and implemented for a cross-product MVC architecture using Python and Tornado for use with Jolitcs and Zuno. When I showed up here it was all a litle haphazard. We needed some organization and I've written many MVCs.
