Objectives

I have a few goals with respect to programming.

Collaborate with other developers to improve human communicationMake computing efficient and enjoyable

The first two of these goals require fundamental changes in our

computing platforms. This is why I'm mostly interested in

framework programming, and why I'm a developer for the Twisted project.

I'm also involved in virtual world simulation and interactive fiction projects and interested

in language and operating system design.

Current

January, 2001 - present

Release Management and Software Development (volunteer)

I work with a team of developers on Twisted, an Open Source

networking infrastructure. I collaborate with the team to design, implement, and

review changes to many parts of the Twisted

system, including the web application server, the chat service, the

remote-object protocols, and the online world simulation framework.

I also manage releases of the software, which includes testing,

developing packaging automation tools, and maintaining

the

server.

Experience

March, 2006 - August, 2009

Software Development

Worked with a team of developers on, a system for managing

deployments of many Ubuntu machines. I worked on the project since it started in 2006, and have designed and implemented major parts of the system. Technologies utilized were Python,

Zope3, Twisted, Postgres, and others.

Among many other things, I worked on

the HTTP-based message queue, which provided a persistent and secure

channel by which the clients and server could communicate

the various data-collection plugins in the client, which integrate

tightly with various Linux systemssystem management plugins in the client, such as the package

and user management systemsthe "ping server", which was a fast and secure

HTTP-based mechanism for the clients to determine whether they should

retrieve new messages from the serverAmazon EC2 integration, which allowed users of Landscape to treat EC2 VMs the

same way they would treat a real machine on the user's network.

August, 2004 - February, 2006

Hobart, Tasmania, Australia

Software Development

Worked with a team of developers on the company's core

product, a document management system for small to medium sized

organizations. This product consists of a management UI written

in PHP, a backend server written in Python utilizing Twisted and

MySQL, and Zope/Plone Products for higher-level applications and

customer-specific applications built on top of the document

manager. I was involved in the maintenance of all parts of this

system, and have done significant development on the Plone and

Twisted-based code.

I was also the lead developer and maintainer of ConveyIT, a

web application for facilitating easy electronic land

conveyancing for Tasmanian solicitors and real estate

agents. Initial development was carried out with a small team of

3-4 developers over 4 months, after which it was cut back to

only myself unless major new developments were taking place. I

also served as technical contact for the client, responding to

support issues and implementing new features. Technologies

utilized were Python, Twisted, Divmod Nevow, Divmod Atop, and OpenOffice.

November, 2003 - August, 2004

Software Development

Developed and maintained an anti-spam service with a small

team. This involved protocol implementation, server

infrastructure, and heuristics for deciding whether a given host is

a spammer or not. Protocols involved were DNS and SIQ (Server Index

Query). Technologies utilized were Python and Twisted.

November, 2003

Frankfurt, Germany

Training

Gave three full days of training to programmers at Ypsilon on

the networking

framework. Topics covered were protocol implementation,

components, Deferreds, Twisted Cred, Perspective Broker,

twisted.web, and XML-RPC.

Amy ThompsonAugust, 2003 - October, 2003

Software Development

Implemented an automated test-running system to facilitate

software testing at the Fresno

County Office of Education. Technologies utilized were and, with improvements made

to each.

August, 2003 - October, 2003

System Administration

Set up and maintained two servers running Debian GNU/Linux for the

use of Divmod in the development, testing, and deployment of and other

software. Maintained email servers (Exim), domain server (Twisted

Names), CVS, Asterisk PBX, and various other services.

March 2003 - July 2003

Washington, DC

Software Development

Helped the team to design and implement the PanGalactic

Engineering Framework. Integrated the repository (application

logic and relational database) with various clients, including

a Web UI and a GUI thick client. Technologies utilized were

Python, PostgreSQL (relational database), Twisted's Woven (web

framework), and wxPython (GUI toolkit).

December, 2002 - June, 2003

Software Development

Worked independently on a tool for validating digital coursework

data files. The GUI tool ensures that files in a wide range of

formats meet the quality standards of the Office of Education.

Technologies utilized were Python, Twisted, and Tkinter.

September - December, 2002

Zagreb, Croatia

Software Development

Worked with a team of developers on an open source,

component-based Content Management/Wiki System. Redesigned the

initial version to utilize Twisted's web MVC framework, Woven.

July, 2001 - August 2002

Pittsburgh, Pennsylvania

Web Development

Designed and maintained web sites for the company intranet and Internet,

gave support to other Web Designers within NOVA, and explored enhancements

to the navigability of existing web sites. Technologies utilized

were HTML, Javascript, Python, and ColdFusion.

Publications

Getting Twisted - An article I wrote

professionally for . It

is a general introduction to implementing a protocol with

Twisted. The

is available on the PyZine web site.

Releasing Large Python Projects - I gave a

talk at PyCon 2003 about the Twisted release management

process. The

are available on my web site.

Minor Projects

I am involved in the interactive fiction community. I run the blog site and contribute to the project.I implemented two different Lisp-like languages: one

compiler and one interpreter. The compiler was for an

experimental syntax that attempted to bring some of the

niceties of Python's syntax to the Lisp language. It compiled

to Python bytecode. The interpreter was an experiment in

restricted execution environments, and was written in Python.

I wrote a graphical mind-mapping application named

Infogreater.

Skills

Programming Languages

Operating Systems

Debian GNU/LinuxWindows NT, 2k, XP, Vista

Interests

I'm interested in interactive fiction, virtual world simulations, Wikis,

education, content management systems, programming languages,

operating systems, the mechanics of abstraction, and

debate. More information on these subjects is available on my

website, http://radix.twistedmatrix.com/.
