Roden AlvinCosejo
aka Rudevin, full-stack creative developer
A full-stack creative developer blending game-server engineering, modern web development, and visual design. I build polished, scalable products, from FiveM systems to a live esports platform, and I love turning ideas into things people actually use.

Featured Projects
BentoLink
A link-in-bio platform for the Philippine creator economy, built around the tiles Filipinos actually run on: GCash, Shopee and TikTok Shop, rate cards, and Messenger. I self-host the whole stack on a Hetzner VPS instead of a managed platform, so most of the work is production infrastructure: a multi-stage Docker build, PocketBase isolated on an internal-only network with no public domain, Cloudflare in front for DNS, WAF and SSL, and scheduled off-site backups to R2 that verify their own output rather than assuming the upload worked. Hardened for a free tier that is open to abuse: SSRF-guarded link scraping that re-validates after redirects, visitor IPs stored only as HMAC digests, uploads sniffed by magic bytes and re-encoded through sharp to strip EXIF, strict CSP, and privilege flags kept in a server-only collection so nobody can self-grant premium.
Associate Dispatch System
Client work for an events studio, shared with permission; the client and their brand stay private. Off-the-shelf scheduling tools broadcast a shift and let whoever answers first take it, which is not how a studio books people it has actually vetted. I built targeted dispatch around a two-tier state machine where an associate accepting an offer is deliberately not the same event as the studio confirming them, so a role is never double-promised, and confirming one person closes and notifies everyone else on it. Around that core: multi-tenant Postgres with row-level security on every table, a payroll ledger that snapshots pay at confirmation so history cannot drift, a 60-day lock-in enforced in the database rather than the UI, double-booking and unavailability warnings at offer time, reusable role-to-people templates, and email, SMS and in-app notifications behind one swappable seam. Built for a 50-100 person roster, with a WCAG 2.2 pass.
Personal Resume Website
This site, a modern, fully responsive portfolio. Migrated from vanilla HTML/CSS to Next.js, TypeScript, and Tailwind CSS, with custom canvas particles and animated effects.
FiveM Custom UI
A sleek, interactive in-game user interface built for FiveM servers using modern web technologies inside the CEF/NUI layer.
LuaNUIJavaScriptOX Inventory Addon
Advanced integration and customization of the OX framework inventory mechanics: new item behaviors, stashes, and UI tweaks.
LuaOX FrameworkServer Core Framework
A robust, highly optimized server core infrastructure designed for high player loads and clean, extensible resource architecture.

PaletteGuard
TypeScriptnpmGitHub ActionsAccessibilityA build-time accessibility check for chart palettes. It simulates protanopia, deuteranopia and tritanopia, measures every colour pair with CIEDE2000, and calibrates the pass/fail floor against Bang Wong's published colourblind-safe palette instead of an arbitrary number. Runs as a CLI or GitHub Action and exits non-zero, so an unreadable palette fails the build rather than shipping unnoticed.
$npx paletteguard palette.json
tokendiet
PythonClaude CodeDeveloper toolingMITA Claude Code plugin that audits a project for the context costs you never see: oversized CLAUDE.md files that reload on every message, skill-listing overhead, and the actions that silently invalidate the prompt cache mid-session. Python standard library only, no dependencies, distributed through a plugin marketplace.

RudeSync
RustTauri 2Svelte 5SQLiteAn offline-first desktop app that puts tasks, client projects, invoicing and personal loan schedules in one place, with no account and no server. Rust and Tauri 2 over SQLite with a Svelte 5 front end: milestone-based billing, PDF invoice generation, a floating always-on-top task widget, local backups, and CSV export.
