A companion chart for the videogame Vampire Survivors, showing weapons, passives, and evolution paths in a single searchable view. Around 20,000 monthly visitors. Built with Next.js 15, React 19, Tailwind 4, and Zustand, with Fuse.js powering fuzzy search across hundreds of game items. Game art is pipeline-converted from PNG sprite sheets into CSS background-position icons at build time, keeping the runtime asset footprint small. Hardened with a strict Content Security Policy, X-Frame-Options, and Referrer-Policy headers.
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.
Rico Rico is a demo frontend for a restaurant-reservation booking platform that connects diners with its partner restaurants.

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.
A web app built with React, Firebase, TailwindCSS, and Mantine.dev and bootstrapped from my React starter template. The server state was handled with React-Query, and the global client state was conducted with Redux Toolkit. It allows the user to schedule habits. For example, the user may create a routine titled 'water the plants' with a recurrence of one day.
The Weather Wardrobe Wizard sends users weather forecasts and corresponding clothing suggestions. Users can toggle between metric and imperial units, list and image view of clothing, and light and dark themes. Selections are locally stored for guest users, while signed-in users have persistent data stored in Firebase. Premium users enjoy AI-powered packing recommendations from OpenAI. The application was developed with Next.js, React, TypeScript, and Zustand and combines weather forecasts with clothing advice. OpenWeather API powers the real-time data, and the UI is crafted with Chakra UI. Firebase Firestore handles real-time database updates, while Stripe facilitates payments for premium services. Multi-language support and error tracking with Sentry are other key features.

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.
Hub-and-spoke food-safety platform that hosts multiple consumer-facing tools (menu-decoder, dishscout, tinyplates) under a single Google OAuth + magic-link auth, shared Stripe billing, and a credit-based API gating model. Built as a Bun monorepo with Vertical Slice Architecture on the backend: Express 5 with per-feature modules, a static Astro + Vue (TanStack Query) frontend, an Expo React Native shell, and a shared package layer (@repo/api-types, @repo/db, @repo/config) that prevents the data layer from leaking into the contract layer. Ships with custom architecture audit scripts (VSA cross-slice violations, FCIS purity, code-entropy) that run as part of the build pipeline. PostgreSQL + Drizzle, Redis for sessions and rate limiting, deployed via PM2 on a shared Hetzner VPS.
Digital storefront for templates and downloadable products with both one-time purchases and a credit-based top-up model. Stripe-backed checkout for products and credit packs, subscription support, signed download URLs for owned products, and per-IP API rate limiting. Categorized product catalog (templates section and category index pages) and a blog with category routing for SEO. Built as a Bun monorepo: Express 5 backend with per-feature slices (auth, credits, downloads, owned-products, payments, rate-limit), static Astro + Vue frontend, PostgreSQL + Drizzle, Redis-backed sessions and rate limiting, PM2 on a Hetzner VPS.

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.

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.
