Work experience

PHP Ecosystem Security

In September 2026, I joined the PHP Foundation's Ecosystem Security Team to work on hardening the PHP codebase and addressing non-security issues that are reported to the security team. See my blog post for more details.

WikiTeq

I worked at WikiTeq from January 2023 until May 2026 as a Technical Project Manager, working with a team of developers around the world to support clients that use MediaWiki, including major corporations and government agencies. As part of my work at WikiTeq, I developed multiple MediaWiki extensions, though most of them are private. My contributions made as part of my work at WikiTeq are all available under the account @DanielButAtWork on GitHub. Public extensions that I created include:

• MixedVisibilityFiles: Support making some on-wiki files public and others private
• ZoteroConnector: Import references and attachments from Zotero into a wiki
• MarkdownPages: Add support for markdown as a page content model
• HoneyPot: Implementation of a honey pot during account creation
• MinimalExample: Demonstration of the process of building an extension

I also gave talks at multiple MediaWiki-related conferences on behalf of WikiTeq. Those talks were recorded and are available publicly:
