My work

I write articles on the English Wikipedia and work on numerous tools and extensions in the Wikimedia technical ecosystem. As of March 2026, I've accumulated over 18,000 edits on the English Wikipedia and across 20,000 on all Wikimedia projects. On the technical side, I have code merging rights for MediaWiki core, extensions, and skins and I primarily focus on various Toolforge tools and userscripts. I've led the development of Ultraviolet and RedWarn, both widely-used counter-vandalism tools on the English Wikipedia, and Deputy, a contributor copyright investigation tool. On the movement side, I am an ESEAP RFC member and ESEAP Community Connector.

About Me

Hi! I'm Chlod, a student, software developer, and Wikipedia editor of 7 years. I'm a volunteer contributor for Wikipedia and its sister projects, and a volunteer software developer for the Wikimedia movement's technical ecosystem. I'm also a mentor, a leader, and an active contributor to the ESEAP Hub and regional movement initiatives.

On the Wikimedia projects

I'm an active English Wikipedia contributor, and have worked on numerous articles throughout my time as a Wikipedian. I've written most of the content for Kind Words (video game), 2020 Pacific typhoon season, Typhoon Goni, Typhoon Vamco, 2021 Pacific typhoon season, Tropical Storm Dujuan (2021), Tropical Storm Conson, Primitivo Mijares, Tropical Storm Megi, Tropical Cyclone Wind Signals, Typhoon Noru, 2023 Philippine airspace closure, Ako si Ninoy, Typhoon Doksuri, Anti–Red Tape Authority, Until Then, Strinova, Edgar Matobato, Typhoon Fung-wong (2025), Easy Delivery Co., and Dupax del norte anti-mining protests. I'm a member of WikiProject Philippines, WikiProject Copyright Cleanup, WikiProject Tropical cyclones, WikiProject JavaScript, WikiProject Accessibility, and WikiProject Computer science.

Outside of writing work, I have template editor rights and I help maintain templates and modules on the wiki. I am also a new page and pending changes reviewer. I also occasionally do counter-vandalism work, which was my main area of expertise in 2020, and I have rollback rights.

On Wikimedia Commons, I'm a photo uploader and an autopatrolled user. I upload photographs that I take with my DSLR camera, and also diagrams, illustrations, and maps. I also occasionally edit Wikidata, creating items for articles that I create and updating related items.

On the Wikimedia technical ecosystem

Most of my work nowadays involves technical work in the Wikimedia movement. These span from small userscripts to tools and MediaWiki extensions. I got started making user scripts for the English Wikipedia in 2020, eventually joining the development team for RedWarn. I've worked on the following major projects:

Name	Description	Type	Date
RedWarn	Modern Wikipedia counter-vandalism tool. Originally developed by Ed6767.	User script	2020 – present
Zoomiebot	Bot on the English Wikipedia. Handles page indexing and archive generation.	Bot	2021 – present
wikimedia-streams	JavaScript library that provides an abstraction over Wikimedia EventStreams.	Library	2021 – present
Ultraviolet	Wikipedia counter-vandalism tool. Successor to RedWarn, rewritten from the ground up to eliminate technical debt.	User script	2022 – present
Deputy	Contributor copyright investigation workflow tool. The only script of its kind, it helps users handle CCI cases on the English Wikipedia.	User script	2022 – present
Tech Contribs	Gives a summary of a developer's technical contributions to the Wikimedia movement. I created this tool in 2024.	Toolforge tool	2024 – present
Earwig's Copyvio Tool	Tool used to scan articles for copyright violations. I became a maintainer of the tool in 2024.	Toolforge tool	2024 – present
Nuke	Used to mass delete pages. I work on Nuke tasks in my free time.	MediaWiki extension	2024 – present

I'm an administrator on the Test Wikipedia and a bureaucrat on the English Beta Wikipedia. In 2025, I gained code merging rights to MediaWiki core, extensions, and skins on Gerrit.

You can view a summary of my contributions on Tech Contribs, a tool which I developed. My code contributions can be found either on Gerrit, Wikimedia GitLab, or GitHub.

All of my contributions to the Wikimedia technical ecosystem is available under free and open source software licenses. I make it a policy to strive for transparency and integrity in every line of code I write.

On the Wikimedia Foundation

I'm a Tagalog translator for the Wikimedia Foundation. You can see my edits under this contract at Special:Contributions/Chlod (OCTG).

I worked as a contract software engineer in a three-month project by the Moderator Tools team to improve the "Nuke" MediaWiki extension, from November 2024 to January 2025. You can see more info about that project on the MediaWiki wiki.

In September 2025, I joined the ESEAP Regional Funds Committee, under the banner of youth and tech representation.

On the Wikimedia movement

I'm an active participant in the ESEAP region and I regularly collaborate with other people in the movement. I work with (and not under) multiple Wikimedia and Wikimedia-related groups based in the Philippines and with individual contributors without affiliations, just like myself. Since 2024, I've brought a guestbook to all Wikimedia events that I've attended. I've gotten signatures from a lot of Wikimedians around the world, and it's a constant reminder of how diverse this movement is.

I started involving myself in movement activities during the ESEAP Conference in 2024. I had already been joining the ESEAP Community Call in the months leading up to the conference. Here, I learned about our regional affiliates, the ESEAP Hub, and got to meet many other Wikimedians in my region. When Manila was selected as the host of the next ESEAP Summit, I volunteered to join the organizing team. We eventually held ESEAP Strategy Summit 2025 in the Philippines, and I served as the communications lead for the Summit, eventually helping out with other work later down the line. I later joined the Program Committee for ESEAP Conference 2026 which led to the first ever Youth-focused track and mini-summit in a regional ESEAP conference.

In 2026, I hosted a Wikipedia 25 birthday party with Chipmunkdavis in Metro Manila, bringing together a wide variety of Wikimedian editors in the Philippines national capital, with the eventual goal of increasing the connection between the mostly-independent editors in the region. I also helped host the Wikipedia 25 birthday party during the FactorDay section, and helped set up the celebratory logo changes for the English Wikipedia.

My push for youth initiatives began with my participation in the inaugural Wikimedia Youth Conference, where myself and other members of the youth began collecting our visions for youth collaboration within the region. As someone who's been working on the Wikimedia projects since my teenage years, I wanted to be able to provide a proper support system to those like me who started out working on Wikipedia alone. Under the banner of the youth, I was voted as an ESEAP Community Connector in November 2025. I'm a founding member of the ESEAP Youth Group, a new initiative of the ESEAP Hub.

I was mentor for the Wikimania Hackathon in 2025 and I've provided mentoring and assistance to many other developers during various events since my first Wikimania in 2023. I've also long provided help in various off-wiki channels, mostly on the English Wikimedia Community Discord server. I've given two talks about my work: one in Wikimania 2021 about our work on RedWarn and another in 2023 about my work on Deputy.

Outside of Wikimedia

Outside of the movement, I'm a college student and open source software developer based in the Philippines. You can find more information about my off-wiki work on my website.
