Ralsei Bot

The Ralsei Bot is a Discord bot initially made in 2018 shortly after the release of Deltarune. Initially a small pet project, it is now used by over 7,000 Discord servers. This was my first Discord bot and my first JavaScript project, with the original code having been written entirely in vanilla JavaScript. It has since been rewritten in TypeScript (as my first project to ever be written in TypeScript) and has been under significant optimization to orchestrate the bot's performance on all of the servers it is a member of.

The bot exists with the help of Demirramon's Undertale Text Box Generator. "Ralsei" is an original character created by Toby Fox.

Wikipedia

Wikipedia is the world's largest freely-accessible reference work. I have been editing Wikipedia since 2019, initially getting started on counter-vandalism and later moving on to content creation. Later on, my focus shifted on more technical work: creating volunteer-made tools for users, maintaining bots, and developing templates for use on articles.

Arguably, my experience editing Wikipedia has given me a large range of skills. Most evidently, it has promoted my writing skills, but also my communication skills, since editing is a collaborative effort.

Hourglass

The Hourglass server is a self-managed (but not self-hosted) virtual private server that contains nearly all of my existing (non-Wikipedia) projects. It's used for most of my day-to-day operations, and for services that can be found on my website. It's also used for testing projects, proxying connections to and from my computer, and for hosting my website.

Most of my experience in system administration, Linux system management, and continuous deployment come from operating Hourglass.

RedWarn

RedWarn is a Wikipedia counter-vandalism tool initially made in April 2020, meant to be an alternative to the existing counter-vandalism tools which were first developed for Wikipedia in the early 2000s. It is currently used by hundreds of Wikipedia editors for counter-vandalism and vandalism patrolling. RedWarn is maintained by a team of volunteers.

The RedWarn team gave a speech about the project at Wikimania 2021, which was followed by a consultation with a few editors in the Wikimedia space. RedWarn was rebranded in February 2022 as Ultraviolet after a full rewrite of its source code.

PAGASA Parser

The PAGASA Parser was first developed as a way to programmatically generate tropical cyclone wind signal tables on Wikipedia for active tropical cyclones threatening the Philippines. It has since been rewritten and expanded to parse out any recent Tropical Cyclone Bulletin data and export all of those into a JSON format. The PAGASA Parser is now composed of multiple packages and a web interface for processing data.

JTWC Archiver

The JTWC Archiver was made to resolve the ephemeral existence of Joint Typhoon Warning Center advisories, and make them available under a reliable archive which runs periodically without the need for human intervention. The archiver has since been used on numerous Wikipedia pages as a reference for JTWC products. For redundancy, the advisories are backed up one more time on the Internet Archive every year.

PIDSR Check

The PIDSR Check app was a Flutter application which aimed to assist barangay health workers in identifying if specific symptoms fit into categories of notifiable diseases as indicated by the Philippine Integrated Disease Surveillance and Response Manual of Procedures. The project was dropped following the conclusion of S.Y. 2021–2022, where my research project switched from this app to PiliPisay (found below).

The Pisay Explorer

The Pisay Explorer is the Philippine Science High School – Cagayan Valley Campus' school publication in English. Due to the COVID-19 pandemic, articles were published online instead of through newsletters. The Pisay Explorer released one set of articles before going on hiatus until the release of Kinaadman, the joint English and Filipino publication of the school. The website is now inaccessible as its domain has expired.

Wikimania 2021

Wikimania 2021 is the first fully-online version of the annual Wikimania conference, a conference for the Wikimedia movement, its editors, and its participants. I gave a lecture about RedWarn and modern counter vandalism tools along with RedWarn's original author to a live online audience.

Zoomiebot

Zoomiebot is a Wikipedia bot used for performing mundane tasks on Wikipedia, all of which currently do not require approval from the English Wikipedia Bot Approvals Group. Part of its tasks include automatically archiving all PAGASA bulletins and keeping track of all WikiProject Tropical cyclones articles, drafts, and project pages.

PiliPisay

PiliPisay (working name "Caster") is an end-to-end verifiable election system which uses Microsoft's ElectionGuard for ballot encryption, decryption, and tallying. It was initially developed as a replacement for existing methods of elections which either compromised security or voter trust. It is built for small-scale internet-based elections, primarily the Philippine Science High School – Cagayan Valley Campus Supreme Student Government (SSG) Elections, which switched to remote learning due to the COVID-19 pandemic.

Ultraviolet

Ultraviolet is a TypeScript rewrite of RedWarn rebuilt from scratch. It aims to resolve the problems of the original RedWarn script and extend beyond its original capabilities. It is currently maintained by a team of 8 volunteers, with myself as the current project lead.

Deputy

Deputy is a contributor copyright investigation and copyright cleanup assistance tool for Wikipedia. The first of its kind, Deputy is used by copyright cleanup editors to streamline the process of investigating and reporting copyright violations on the wiki. Deputy was the subject of a Wikimedia Foundation Rapid Grant and I was provided a one-time fund of US$2,000 for its initial development.

Wikimedia Foundation

The Wikimedia Foundation is a 501(c)(3) non-profit organization that operates Wikipedia and other free knowledge projects. I translate for the Wikimedia Foundation under its organization communications translators group, and I'm responsible for translating select material from the Foundation into Tagalog.

wikimedia-streams

wikimedia-streams is a JavaScript library that connects to the Wikimedia Foundation's Event Platform to receive real-time changes from every wiki on their infrastructure. It can receive recent changes, page creations and deletions, and more, either in real-time or from a few hours to days earlier. The library is written in TypeScript and comes with event typings for each supported stream. The library was first released in June 2021, and received its v1.0 release in May 2023.

Wikimania 2023

Wikimania 2023 was the return of in-person Wikimania conferences. It was held in Singapore at the Suntec Singapore International Convention and Exhibition Centre. I gave a lecture about Deputy's development, participated in the Wikimania Hackathon, advocated for more resources in copyright cleanup tooling, and met up with hundreds of Wikimedians, both from around the world and fellow editors from the East, Southeast Asia and the Pacific region. My travel was fully funded by the Wikimedia Foundation, as a scholarship recipient.

Google Developer Groups on Campus Mapúa University – Manila, Philippines

Google Developer Groups (GDGs) are community groups for developers interested in Google technologies. GDGoC – Mapúa (formerly GDSC Mapúa) is the Mapúa University chapter of GDGs on Campus, established in 2023. It is recognized by the Mapúa Council of Organizations, and accepts students from different majors. I am part of its first batch of members, and served as a technical committee member in 2024.

Wikimedia Hackathon 2024

Wikimedia Hackathon 2024 is the 2024 iteration of the annual Wikimedia Hackathon, where developers of MediaWiki extensions, tools, and gadgets convene to build software over a few days. This year's iteration was held in Tallinn, Estonia. I worked primarily on the MediaWiki Nuke extension, which allows mass deletion of pages, along with engineers of the Wikimedia Foundation's Moderator Tools team. My travel was fully funded by the Wikimedia Foundation, as a scholarship recipient.

ESEAP Conference 2024

The ESEAP Conference is a regional conference aimed at strengthening collaboration between Wikimedians in the East, Southeast Asia and the Pacific region. Its 2024 iteration was held in Kota Kinabalu, Malaysia. At the conference, I learned invaluable information about the inner workings of the ESEAP Hub, its community, its user groups, and of course, its editors. I got to connect with other Filipino editors who I usually don't see in the Philippines, along with many other editors in the region. My travel was fully funded by the Wikimedia Foundation, through Wikimedia Community User Group Malaysia, as a scholarship recipient.

A report of my experience at the conference can be found on the Wikimedia Meta-Wiki.

Wikimania 2024

Wikimania 2024 is the 2024 iteration of the annual Wikimania conference. It was held in the International Congress Center in Katowice, Poland. At the conference, I had discussions with other Wikimedians about the upcoming 2025 ESEAP Summit, participated in numerous discussions about product and technology, and collaborated with other programmers at the Wikimania Hackathon. My travel was fully funded by the Wikimedia Foundation, as a scholarship recipient.

Wikimedia Foundation

The Wikimedia Foundation is a 501(c)(3) non-profit organization that operates Wikipedia and other free knowledge projects. I worked with the Moderator Tools team at the Foundation for a novel short-term project of three months, starting on November 2024, where we worked on improving the "Nuke" extension, which allows administrators to mass-delete pages created by abusive users. The short-term project aimed to address numerous feature requests that have piled up over the years.

Scrupy Cup 2

Scrupy Cup 2 is the second iteration of the Scrupy Cup, a community-run osu! standard tournament hosted on Twitch streamer scrupydoo's channel. I was originally part of the graphics team, designing graphics, overlays, backgrounds, and other visual assets for the tournament. As demand for other roles grew, however, I ended up also streaming, commentating, and co-organizing the tournament.

Archives of streams are available in scrupydoo's Twitch VODs channel.

Wikimedia Hackathon 2025

Wikimedia Hackathon 2025 was the 2025 iteration of the annual Wikimedia Hackathon, where developers of MediaWiki extensions, tools, and gadgets convene to build software over a few days. This year's iteration was held in Istanbul, Turkey. I worked on Tech Contribs, a website where developers involved in the Wikimedia ecosystem can easily see their technical contributions. Besides this, I did a lot of talking, consulting, networking, and mentoring of some of the newer attendees. The event culminated in a nomination to provide me reviewing rights for MediaWiki, its extensions, and skins. My travel was fully funded by the Wikimedia Foundation, as a scholarship recipient.

Wikimedia Youth Conference 2025

Wikimedia Youth Conference 2025 was the first internationally-oriented youth conference for the young contributors of the Wikimedia movement. It brought together young Wikimedians from all over the world with the goal of identifying how to get the youth involved in the movement. The conference was be held in Prague, Czech Republic. There, we decided to take the first steps in organizing an East, Southeast Asia, and Pacific regional youth group, and laid out our priority steps to make this a reality.

My travel was fully funded by Wikimedia Czech Republic, via the support of the Wikimedia CEE Hub, as a scholarship recipient.

ESEAP Strategy Summit 2025

The ESEAP Strategy Summit is a regional strategy summit aimed at shaping the future of the Wikimedia movement within the East, Southeast Asia and the Pacific region. It happens biennially, alternating yearly with the ESEAP Conference. The 2025 Summit was held in Manila, Philippines, my current city of residence. I was part of the core organizing team as an independent Wikimedia volunteer managing external communications and Trust and Safety, and co-organized the event with four other local Wikimedia user groups. Later on, I began to do more in the organizing team as demand for other roles grew.

During the Summit, I caught COVID-19, and was unable to attend physically, but I took on the role of being a remote organizer, handling tasks that didn't need to be done in person and also interfacing with the local health department to ensure the safety of all participants, especially since the Summit brought together almost a hundred Wikimedians from all over the region.

Wikimania 2025

Wikimania 2025 is the 2025 iteration of the annual Wikimania conference. It will be held in Gigiri, Nairobi, Kenya. My travel will be fully funded by the Wikimedia Foundation, as a scholarship recipient.
