Portfolio

I wrote a rather involved article about helpful Python tricks that reached the front page of Reddit and is still the first Google result under 'Python Tips'. You can view it at http://www.siafoo.net/article/52

Python Tips, Tricks, and Hacks

Created for NBC's advertising sales department, this site features a custom Django implementation, giving it a full-featured review-before-publish and revision control system. It is fully adminable through a custom interface. I designed and programmed this reusable system on top of Django, as well as creating the rest of the database and backend for this complex site.

NBCStations.com

The home page for the California Pizza Kitchen chain is fully customizable via a custom Django interface. Items can be priced per location, and locations are automatically located and mapped via the Google Maps and Yahoo Placefinder APIs. Job applications are automatically accepted and collated.

CPK.com

Created to promote the Kelsey Grammar show Boss, this site aggregated tweets about political, church, education, and sports scandals. It used the Twitter streaming and search APIs to collect all tweets mentioning certain keywords, and a robust spam filtering system to only show relevant results. Users could view tweets by category, topic, or location (using a map). I wrote the entire backend, including the aggregator and an administrative panel, in Django, PostgreSQL, and Python. I provided a robust RESTful API for frontend developers and third-party advertisers to grab trending tweets and topics, and to post tweets back to twitter through the site.

It was a pleasure to work with dji again. He is a great communicator, striving to give his clients whatever they need and continues to stay connected after project completion to ensure smooth integration in to projects.

I'll certainly be hiring David again. He worked hard to produce another ArcGIS toolset for me, wlooking forward to working with him again.

Simple database-driven iPhone App

David did a fantastic job of implementing my requirements. He delivered high quality code ahead of schedule. He is a great communicator with a keen intellect. I found his ability to ask insightful questions really useful. Together, we clarified the requirements. The functional requirements were then accurately translated by David into well written code. His approach contributed significantly to the success of the project. I look forward to working with DJI again soon.

I've done various short-term work for different clients, from simple CSS layouts to complex iPhone applications and .NET APIs. Usually these were prototypes of some sort or another. My most complex was building an iPhone application which autodiscovered and communicated with a .NET json API (which I also built), which in turn modified the database for an existing (somewhat mental) restaurant Point of Sale system, and also printed out receipts. Technologies used: Objective-C, C#, ASP.NET, JSON, i

I created and deployed interactive internet marketing campaigns - mainly websites and Facebook applications - to meet the diverse and changing needs of clients. I was involved in the entire process, beginning with brainstorming strategies, implementations, user flow, and basic designs and wireframes. After the designers and UI guys had a crack at it, I'd implement the backend, usually solo, and usually in python and Django, but sometimes in tornado (asynchronous python) or node.js. I created a ton

Siafoo is a website to help programmers share code and experience. My business partner and I created, designed and implemented the entire thing. Almost all of the front-end implementation was mine. The site supports multiple browsers, including those without Javascript, CSS, or images (for the hardcore lynx users!). It was built using all open source (free) libraries (we only pay for storage & bandwidth). For more information, you can view a talk we gave to the Linux Users Gcoup of Davis: http://www.
