Principal Architect (9/12–)
I consult internally on standards participation and strategy, and serve as Akamai’s W3C Advisory Committee representative.
Additionally, I help with HTTP API design issues and generally serve as an expert on HTTP and HTTP APIs.
Systems Architect, Subject Matter Expert (8/11–8/12)
I was responsible for defining and executing Rackspace’s Cloud Standards strategy, as well as consulting on and improving Rackspace and OpenStack HTTP APIs.
Senior Principal Technical Yahoo! (1/06–8/11)
I was hired as a thought leader for Web services using HTTP (a.k.a. “RESTful Web services”; what people tend to call “microservices” today) to back Web sites for Yahoo!’s Media group (approximately 20 sites, including finance, movies and news). This work subsequently served as the basis for Yahoo!-wide Web services recommendations and strategy.
I then transitioned to a role where I served as a subject-matter expert on HTTP, assisting product groups in architecting and implementing services, evangelising its use both inside and outside of Yahoo!, and implementing tools to help developers design and deploy service-oriented interfaces (e.g., WADL).
A major part of these duties was developing, maintaining and supporting Yahoo’s internal build of the Squid Web Cache, including the development of new features (including two new invalidation protocols). Squid was used widely inside Yahoo!, both for front end (e.g., Flickr, 1.8 billion+ hits/day) and back end (e.g., Sports, News, Mail, Frontpage), with a total of more than 35 internal customers. Additionally, I assisted with road-mapping features for the newly open-sourced Apache Traffic Server project.
I also performed a number of standards-related activities on Yahoo!’s behalf, such as representing the company in the W3C Advisory Committee.
Senior Principal Technologist, Office of the CTO (5/02–1/06)
I provided leadership in standards participation and input on the company’s overall technology strategy through innovation and development of strategic technologies, representation of the company to the industry (through conference presentations and standards committees), and by liaising with partners, customers and internal resources.
Research Scientist, Standards and Protocols (9/99–3/02)
I was the company’s resident expert in HTTP, XML, Web services and other Web technologies.
My primary task was the design of Akamai’s “metadata” system, allowing control of distributed server behaviour.
I was also designated as the principal liaison to technical standards bodies and industry consortia (e.g., W3C, IETF, JCP), representing the company to colleagues and partners worldwide.
Internet Project Manager (7/98–9/99)
I championed, designed and oversaw implementation of a worldwide enterprise content delivery network, wrote policy directives for architecture and deployment of caching Web proxies, and proactively diagnosed and remedied performance issues with ML’s internal Web-based research delivery system.
I was also responsible for Web development and support within the Australiasian region, working with management to develop a Intranet and Internet business plan. Additionally, I deployed and maintained enterprise firewall systems for Internet and extranet access.
Web Engineer (7/96–3/97)
I was the Webmaster for this ISP, responsible for design of corporate identity, packaging, sales and support materials in addition to Web design. I also assisted in the deployment of a large-scale Squid proxy cache cluster, and led a team to ship an Internet dialup client on CD-ROM.
La Trobe University, IT Services
I was responsible for oversight of the University’s Web presence. This included:
- Building and maintaining University Web servers and Harvest caching proxies.
- Developing University-wide policies for Internet use, in consultation with legal counsel.
- Designing University Web pages, including information architecture, HTML coding and image creation. Won Best Tertiary Education Site at the 1996 Australian Internet Awards.
