Contributions to Major OSS
Overview
Rito has made high-visibility contributions to the flagship websites of major Open Source Software (OSS) ecosystems used by millions of developers worldwide, including Kubernetes, Ethereum EIPs/ERCs, OWASP, LangChain, and Storybook.
These span radically different domains—cloud infrastructure, cybersecurity, AI tooling, blockchain standards, and UI development—but share the same realities: large audiences, low tolerance for breakage, and a high bar for accepting changes.
Rito’s volunteer contributions are front-end improvements on his own initiative that increase usability and accessibility, reduce friction, and help maintain trust in the projects’ primary documentation and community surfaces. The fixes are often site-wide, aligned to a mobile-first world and covered with comprehensive documentation and testing.
This page highlights code contributions in the form of "Pull Requests" that were officially merged into the projects’ canonical code repositories and deployed to live websites. Not every change remains visible indefinitely as the sites evolve, but the contributions are permanently recorded on GitHub under Rito’s handle, “ritorhymes.”
Quick Highlights
Ethereum EIPs: shipped a site-wide mobile UX fix across the EIPs documentation experience impacting all the main pages and historical ones like ERC-721.
OWASP: shipped a site-wide mobile-centric UX fix in a shared theme powering the owasp.org multi-repo ecosystem.
VWAD (OWASP): rescued the flagship directory from being effectively unreadable on mobile, then implemented Advanced Search + shared pill-based filters for navigating large collections, refactored the table architecture for maintainability and extendability, and introduced a canonical label deduping layer to relax naming conventions while keeping the UX consistent as the dataset grows.
Kubernetes / Storybook / LangChain: targeted UX fixes on site-wide elements that remove friction on high-traffic developer surfaces.

Ethereum EIP Case Study
Project Background:
The Ethereum Improvement Proposals (EIPs) repository is the authoritative standards forum for the Ethereum ecosystem, governing how technical proposals are introduced, discussed, and adopted across a multi-billion-dollar global blockchain economy. Standards formalized here routinely extend beyond Ethereum itself, shaping conventions and implementations across other EVM-compatible blockchains and adjacent ecosystems that inherit or adapt Ethereum's specifications.
The repository contains some of the most influential standards in blockchain history, including ERC-721, which formally defined the concept and terminology of Non-Fungible Tokens (NFTs). Many ERCs originating here serve as foundational primitives for wallets, marketplaces, DeFi protocols, developer tooling, and infrastructure relied upon at global scale.
In addition to application-level standards, the EIPs process is the canonical pathway for proposing and coordinating Ethereum protocol upgrades and network forks, providing a shared framework that the broader ecosystem - core developers, client teams, infrastructure providers, and enterprises - generally aligns around.
The repository is a high-activity hub for ongoing standards development and collaboration, with continuous contributions focused primarily on protocol design and specification rather than site maintenance or structure, reinforcing its role as shared technical ground truth for Ethereum and the wider EVM landscape.
Problem Uncovered:
For years, the EIPs site had a persistent mobile layout problem: on mobile screen sizes, certain content (long lines of text, links, code blocks, and tables) could break out of the normal page container, forcing the entire page wider than the viewport and creating horizontal scrolling and awkward layouts. This impaired accessibility and made navigation challenging. Rito had noticed this behavior in passing over time, but the true scope was not understood, and it had not been formally raised or tracked in GitHub as a systemic issue.

On September 18, 2025, Rito opened the first formal issue and, on his own initiative, performed a structured audit to determine how widespread the breakage really was. That investigation revealed the problem was not limited to a handful of edge-case pages; it affected 100+ pages, including major category pages and heavily referenced core standards. He catalogued affected pages, noted that some were more severely impacted than others, and documented that the underlying causes were systemic and repeatable, rooted in how shared layout and styling handled overflow on mobile rather than isolated content mistakes.
Notably, high-visibility specifications were impacted, including ERC-20 and ERC-721, foundational documents that are routinely cited across the ecosystem and frequently used as reference points by developers, companies, and standards authors.
The Solution:
Rito translated the audit into a single systemic fix that made the site resilient to long, unbroken content on small screens. Instead of patching individual pages, he updated the shared layout and overflow rules in the site’s core styles so that long links, code blocks, tables, and other wide elements no longer pushed the document beyond the mobile viewport.
He submitted the change as a pull request with a detailed breakdown and a live demo to validate the behavior. After maintainer review, it was merged into the canonical EIPs repo, and also merged in the dependent ERCs repo. Once deployed, the fix removed horizontal scrolling on affected pages and reduced the risk of the same class of layout regressions as new standards are added, improving baseline usability and accessibility across one of the ecosystem’s most heavily referenced documentation sites.
Maintainers thanked him for the contribution and invited him to apply the same lens to the upcoming Working Group version of the site.
OWASP Case Study
Project Background:
OWASP (Open Worldwide Application Security Project) is a nonprofit, community-led cornerstone of application security, founded in 2001 and now spanning hundreds of chapters worldwide (342 active chapters listed as of Jan 9, 2026). It is best known for the OWASP Top 10 security risks (current: 2025), plus widely used resources like the Vulnerable Web Applications Directory, and training projects like OWASP Juice Shop.
OWASP's ecosystem is also structurally "many repos, shared theme": projects and chapters commonly live in separate www-project-* / www-chapter-* repos that publish under owasp.org using a shared site theme, reflecting decades of community-scale growth rather than a single monorepo.
OWASP Site Theme Mobile Rescue:
The shared Jekyll site theme used across the owasp.org ecosystem had systemic issues in key elements that caused sitewide breakage — every page was affected, including the homepage. The cookie bar was not fully visible and could not be dismissed because the close icon was off-screen. On mobile load, large sections of the page were hidden by overflow, forcing awkward panning and hurting navigation and accessibility.
Rito diagnosed the root causes and applied a cohesive set of fixes across mobile and tablet breakpoints while preserving the original design intent. He opened an issue and shipped a pull request, and maintainers merged the changes after review.
Impact was immediate and broad: the shared theme stopped breaking layouts across the OWASP ecosystem, and the homepage experience became reliable on mobile and tablet.
VWAD Table Rescue (Phase 1 — Foundation):
The VWAD table is the flagship product of the project, cataloging vulnerable testing projects by category, but it was not configured for reliable mobile responsiveness. On small screens, the layout aggressively condensed: words wrapped into essentially vertical text, and icons and badges shrank to microscopic sizes, leaving much of the content unreadable and difficult to interact with.
Rito opened an issue and shipped a pull request that restructured the table's core display behaviors for usability across breakpoints.
The fix stabilized column sizing, introduced a dedicated scroll container so the table can pan horizontally on small screens without causing page-level overflow, added a max-height so long lists scroll inside the table (keeping the tab controls quickly accessible), and enabled sticky headers so users keep context while scanning large directories.
VWAD Advanced Search (Phase 2 — Feature Expansion):
After the table became reliably usable across devices, the next bottleneck was discoverability: VWAD is a large directory, and "scroll and scan" is not enough once the dataset grows.
Rito implemented an Advanced Search experience that turns the table into a queryable directory — enabling users to compose multi-parameter filters (keyword, technologies, references, GitHub stars, and contributed-year ranges), manage active filters via selected-parameter pills, and apply or clear the full query as a single action.
Here is the opened advanced search modal with multiple configurable parameters
Here the modal is filled out with search parameters and the pill buttons begin to populate. Pressing "accept" is needed to apply the query to the table.
Here there is an "Advanced Search" button used to open the modal, and the current search params are applied as seen in the pill buttons and the text describing the total search results currently present
This feature is designed to be additive (not a redesign of the content model): it preserves the existing table structure while introducing a higher-leverage navigation workflow for real users of the directory.

VWAD Tech Label Normalization (Phase 3 — Durability):
Once Advanced Search was live, a predictable scaling issue emerged: real-world datasets rarely follow strict naming conventions. Technology values can appear with different casing, punctuation, or shorthand (for example, variations like "NodeJS" vs "Node.js"), which can fragment filtering UX and degrade table readability over time.
Rito introduced a canonical normalization layer that maps common aliases to a single preferred label. This improves user experience by preventing duplicate or near-duplicate options in filter controls, and improves developer experience by relaxing naming constraints as the dataset evolves. The normalization approach is also designed to be extensible, so new aliases can be added without reworking the filtering architecture.
OWASP Top 10 RC Mobile:
The 2025 OWASP Top 10 was in pre-release as a Release Candidate on the live, publicly viewable production site, with a watermark on every page to signal the draft status. On mobile, that watermark was not configured correctly and ended up breaking layout, hiding the navigation menu and impacting normal scroll behavior while also adding whitespace more than twice the size of the page content itself.
Rito opened an issue and shipped a pull request that corrected the watermark layout and restored normal layout and scroll behavior across breakpoints. He also alerted maintainers in the OWASP Slack with the issue and fix, and it was promptly merged while the release candidate phase was still active.
