Cover image for Follow the White Rabbit —
Follow the White Rabbit — AI Tarot Oracle Web App A full-stack WebGL + AI tarot experience with user accounts, gamification, and n8n automation. Built from scratch. Follow the White Rabbit is a production-grade interactive web application I designed and built end-to-end — from concept to live deployment. It's an AI-powered tarot oracle that combines WebGL visuals, real-time AI card readings, user authentication, a gamification system, and automated workflows. Not a template. Not a no-code tool. Every line written from scratch. What it does Users arrive to an animated WebGL scene, authenticate via Google, and receive personalized AI tarot readings. Each reading is generated in real time by an AI model, tailored to the user's birth data, name, and chosen question. A gamification layer rewards daily engagement with Oracle Carrots — a virtual currency earned through consistency. Users build a personal profile ("The Blueprint") with numerology, life path numbers, and astrological ascendant. Technical stack Frontend: Vanilla JS + WebGL (Three.js), GSAP animations, custom CSS Backend: Supabase (PostgreSQL database + Google Auth) AI: LLM model — real-time reading generation Automation: n8n workflows for user events and notifications Deploy: Vercel (custom domain, instant CI/CD) What makes it complex This isn't a landing page with a particle effect. It's a full product: WebGL rabbit character with animated states (idle, loading, reveal) Real-time AI integration — each reading is unique, context-aware, personalized Supabase database storing reading history, carrot balance, user profiles Google OAuth authentication flow Gamification logic — streak tracking, daily limits, carrot economy Numerology engine — calculates Life Path, Expression, Soul Urge numbers from birth data Responsive + rotation lock — landscape-only mode with animated prompt Sound design — ambient audio with mute toggle Privacy Policy, Terms of Service, Refund Policy — production-ready legal pages Timeline & scope Solo build. Concept → live product in 8 weeks. Live project 🔗 followthewhiterabbit.cards (http://followthewhiterabbit.cards)

Cover image for PULSE — AI Analytics SaaS
PULSE — AI Analytics SaaS Landing Page A concept landing page for an AI-powered analytics platform built with Three.js, GSAP, and Vite. The hero features a 2,000-particle WebGL sphere with real-time mouse parallax. As the user scrolls, a smaller particle ball detaches from the hero and travels across sections — shifting color, dissolving into a background halo under the pricing cards, then reassembling. Built on a separate overlay renderer with a static camera and viewport-fraction coordinates to keep positioning pixel-perfect across all screen sizes. Stack: Three.js · GSAP ScrollTrigger · Vite · Vanilla JS

Cover image for Just shipped a product site
Just shipped a product site for Pauline's — a Ukrainian manufacturer of natural massage candles. The goal: make the product feel tangible through the screen. What's inside: — Realistic fire and smoke built with a particle shader. Each flame is alive, flickering with its own physics — An oil drop that's born at the candle tip and migrates all the way down the page as you scroll. Getting a smooth sphere-to-teardrop morph without visual seams meant digging into SDF math (signed distance functions). Worth every hour. — 15 scents as interactive 3D lid cards — Oil composition, properties, and care tips Stack: Three.js + GSAP ScrollTrigger + Canvas 2D + Vite → Vercel https://massage.paulinescandle.com/ #WebGL (https://www.linkedin.com/search/results/all/?keywords=%23webgl&origin=HASH_TAG_FROM_FEED) #ThreeJS (https://www.linkedin.com/search/results/all/?keywords=%23threejs&origin=HASH_TAG_FROM_FEED) #GSAP (https://www.linkedin.com/search/results/all/?keywords=%23gsap&origin=HASH_TAG_FROM_FEED) #CreativeCoding (https://www.linkedin.com/search/results/all/?keywords=%23creativecoding&origin=HASH_TAG_FROM_FEED) #Frontend (https://www.linkedin.com/search/results/all/?keywords=%23frontend&origin=HASH_TAG_FROM_FEED)
