Nuxt + Sanity Performance and Core Web Vitals Overhaul
Corporate Project
Three-month performance sprint (Oct-Dec 2025) on an FDA-regulated pharma marketing site built with Nuxt 4, Sanity, and Vercel. Closed 18+ optimization PRs against a September baseline audit. Removed unused WebGL/GLSL bundling, moved GSAP and Google Maps off the global bundle, and converted decorative assets to WebP. Replaced an ad-hoc 39-line lazy-loader with NuxtImg/Sanity provider integration site-wide across ~20 components in a single 66-file PR, restoring responsive sizes, WebP auto-format, and below-fold lazy loading. Split homepage and slug-page GROQ queries into above-the-fold critical and below-the-fold lazy buckets across 9 commits, shrinking the blocking payload that gated LCP on every CMS-driven page. Restructured the full Aeonik Pro font family into a subsetted woff+woff2 layout, added Anaheim with Latin, Latin-Ext, and Vietnamese subsets, and preloaded above-the-fold weights from the Sanity CDN. Configured Vercel edge caching for videos, PDFs, images, fonts, and captions with 7 to 30 day TTLs. Diagnosed and shipped a 4-commit Core Web Vitals fix (prerender/ISR conflict, browser cache headers, animation threshold, asset caching) that moved all 10 indexed URLs in Google Search Console from 'Needs improvement' to 'Good' within 48 hours.

Sanity-to-Vercel ISR Revalidation Webhook
Corporate Project
Built an HMAC-verified Sanity webhook to Vercel ISR revalidation route on a Nuxt 4 marketing site. Replaced time-based revalidation with on-demand invalidation, cutting content publish-to-live propagation from up to 60 minutes down to 2-3 minutes and saving an estimated $40/month in ISR write costs. Included signature verification and selective path invalidation driven by the Sanity document type and slug.

Production Support for an FDA-Regulated Pharma Marketing Site
Corporate Project
Ongoing 24/7 two-shift coverage rotation on a Nuxt 4 + Sanity + Vercel pharma marketing site under FDA-regulated content constraints. Sustained 100% production uptime since November 2025 and a Sentry performance score of 93 (7-day rolling) by January 2026. Diagnosed a 5-day silent GA4 tracking blackout (CSP blocking regional endpoints, missing nonce on inline gtag init), rebuilt CSP with wildcards, wired violations to Sentry, and added a Playwright check asserting window.gtag on every merge. Audited 1.66 TB of monthly Vercel egress and identified hardcoded MP4 patient videos as the dominant cost driver.

Maintenance Agents
Personal Project
Autonomous monitoring system for client websites. Scheduled agents built with Bun and Croner pull data from Sentry, Vercel, and Sanity, hand it to Claude for analysis via the Claude Code CLI (no API key, leveraging the Claude Pro/Max subscription), and post Telegram alerts when something needs attention. Agents are strictly read-only observers; any remediation is left to human approval. The suite covers Sentry triage, dependency hygiene, vulnerability scanning, security-header posture (CSP, HSTS, X-Frame-Options), broken-link patrol, asset-weight audit, Sanity housekeeping, and uptime monitoring. A Hono dashboard provides run history and status. Deployed on a Hetzner VPS managed with PM2.

Elden Survivors
Personal Project
View website: Elden SurvivorsView repo: Elden Survivors
A 'Bullet Heaven' (Vampire Survivors-style) roguelite built on a custom game engine. Auto-firing weapons, horde survival, and RPG stat progression, rendered as code-drawn neon geometry directly on HTML5 Canvas with no graphics library. The engine runs in two modes from the same code: a browser canvas renderer for play, and a headless renderer that runs the full simulation in Node, enabling automated balance testing via Monte Carlo runs and performance benchmarking outside the render loop. Built with React 19, TypeScript, and Vite, with Tweakpane for runtime tuning and dependency-cruiser to enforce module boundaries.

Shared Infrastructure Platform
Personal Project
Multi-tenant persistence layer that hosts every personal and client application on a single Hetzner VPS, keeping per-project hosting cost near zero. Postgres 18 and Redis 8 run in Docker with ports bound to 127.0.0.1 only; remote admin goes through SSH tunnels rather than exposed ports. A single provisioning script (create-app-db.sh) generates a per-app Postgres user, database, and random password and returns a ready-to-use DATABASE_URL; each app is assigned a distinct Redis DB index for isolation. Hard memory caps (1.5G Postgres, 512M Redis) prevent any one app from starving the others. Includes a documented disaster-recovery runbook (pg_dumpall + clean reinit + restore) and an in-place minor-version upgrade path. Powers Maintenance Agents, HelloSafelyFed, Shop Appforgelabs, and several other projects on the same machine.

Income Statement
Personal Project
Personal finance snapshot tool. A CLI command pulls balances from Mercury, Wise, Kraken, Interactive Brokers (Flex Query), and CoinGecko for crypto pricing, converts everything to EUR, and persists each snapshot in PostgreSQL via Drizzle. Accounts without automated fetchers (Santander, Degiro, and similar) fall back to an interactive terminal prompt during the snapshot run, so a single command captures a full picture across automated and manual sources. A Vue 3 frontend backed by a Hono API charts the time series. Each provider's quirky response shape is parsed and normalized through Zod schemas.

Improving Accessibility and Styles of a PHP Website
Corporate Project
This is a website to view and publish data samples related to scientific publications. As the front-end and accessibility developer, I performed accessibility audits, created GitHub issues, and fixed existing issues. I also updated the admin pages from legacy to modern styles and updated the style guide to include these updates. Finally, I revamped and improved the accessibility of a Vue widget used to upload large files.

Travel Booking Websites Improvement
Corporate Project
Onboarded as a front-end developer, I championed major improvements in the Nuxt.js a codebase for travel website allowing package bookings. I targeted large, complex components and initiated a shift towards smaller, single-responsibility modules, vastly enhancing code clarity and maintenance. I corrected Vuex store misuses, transitioned actions to getters, and refactored while shipping features delivery timelines. I delivered features such as advanced web search filters and dynamic campaign pages, boosting user experience. I also filled gaps in end-to-end testing, solidifying the codebase against potential bugs. The engagement culminated in a handover to a new developer, leaving behind a substantially improved and streamlined codebase.
Improving Accessibility in a React App
Corporate Project
This project involved improving the accessibility of a React app for a client. After an initial accessibility audit, we identified several tickets that needed to be fixed. I worked on these tickets in a separate branch and made sure to submit pull requests that were easy to understand and review. Once the important tickets were completed, I conducted a full accessibility audit of the app to identify additional issues. I grouped these issues into new tickets and prioritized them based on their importance. Then I worked on the most important tickets to fix them. As a result, the app became fully accessible, and a second accessibility audit resulted in essentially zero issues reported. My contributions to this project helped ensure that the app was usable and accessible to a broader audience.

Landing Page Editor
Corporate Project
A Nuxt component library built for Jobsrepublic was integrated with the Storyblok CMS so that content managers could create and edit new landing pages from scratch. Every component included team brainstorming with the content creators to cater to their needs, a development phase and accessibility, and performance and SEO audit to achieve a high lighthouse rank. Changes requested by the team were implemented often within the same day. Tailwind CSS was used for styling, and the UI design was adapted from that provided by the Tailwind UI template library. Each landing page was its own multipage site.
