Cover image for Poke Price is web app
Poke Price is web app that tracks Pokémon card resale prices across major marketplaces and shows you exactly where your prices are out of step with the market. I built it solo with Cursor as an AI-assisted development workflow 🛠️ Sellers can upload their Shopify product listing in CSV (as exported from Shopify), the app matches each card against a reference catalog (API), scrapes and aggregates live prices from multiple reference platforms (API or Custom Scraping), and shows each item side by side with the current market price — then lets you export a corrected CSV ready to re-import into Shopify. It also includes a custom OCR pipeline (built with Cursor & Tesseract) that reads a card straight from a photo and identifies it automatically 🔍 — handy when the Shopify listing data is incomplete or a bit messy. Pokémon cards and Shopify are just the starting point — the same approach (matching, scraping, price comparison) applies to pretty much any market with scattered pricing and a reference catalog, and to other e-commerce platforms beyond Shopify. Stack: Python · web scraping pipeline (multi-source, rate-limited) · Cursor (AI-assisted dev) · card reference API integration · custom OCR for card identification · CSV import/export · caching layer for pricing data

Cover image for A mobile app (iOS +
A mobile app (iOS + Android) that compares Uber, Bolt, Heetch, Citygo and G7 in real time so users pick the cheapest ride before opening a single app. Built solo, end to end — mobile apps, backend API, and mapping infrastructure. One engineering decision worth mentioning: instead of defaulting to Google Maps everywhere (and its licensing costs), I used Apple Maps natively on iOS and built a self-hosted map tile pipeline on Cloudflare for Android — cutting third-party dependency and long-term costs while keeping both platforms fast. Stack: React Native (Expo) · TypeScript · FastAPI · Python · PostgreSQL-free LRU caching · OSRM (routing) · MapLibre · Cloudflare Workers · Firebase · EAS Build → App Store & Google Play

Cover image for CLTO Hockey is the club
CLTO Hockey is the club where i play field and indoor hockey since I'm 6 years old 🏑, growing up I got involved in the organization of the club and now I help them improve their digital presence by managing the social media of the club Instagram, Facebook, TikTok. Few years ago they needed a rework and a redesign of the website, as I was already working as a digital project manager in a company updating their websites and mobile applications, I worked on a new identity and built the website from scratch using Canva and Figma for the wireframing 🖽. They needed something easy to work with 🛠️ and not too complicated to udpate so i chose to build the website using Wordpress and a page builder that I had already worked with : Brizy. The page builder allowed me to recreate the wireframes on this new wordpress in seconds, within a few days of work the new website was live ⚡. Stack : OVH hosting, Wordpress, Brizy page builder, Google Recaptcha, Hotjar for the analytics.
