Projects

Applications for my League collection, team food orders and a band’s archive.

01

Personal collection · App + collector

Skinfolio

In use

My League collection

Explore project

Syncs my collection from the League client to browse skins, chromas, offers and acquisitions.

  • React
  • TypeScript
  • Node.js
  • Supabase
Inside Skinfolio: decisions and development

The challenge

Understand a growing collection without getting lost among skins and chromas.

My contribution

I built the React and TypeScript interface and a Node.js collector that syncs my collection from the League client to Supabase.

Technical decision

I separated CommunityDragon's public catalogue from personal collection data, so skins and artwork can stay up to date without duplicating them in the database.

Result

A collection browsable by champion, ownership and rarity, with offers, chromas and an acquisition history.

Team orders · App + scraper

In use

Food orders for the team

  • React
  • TypeScript

  • Playwright
  • Supabase
Inside MenuBox: decisions and development

The challenge

Coordinate a weekly group order without losing anyone's choices.

My contribution

I built the ordering flow, administration tools and a Python and Playwright scraper that extracts public menus and opening hours from 14 restaurants.

Technical decision

The scraper validates each catalogue before publishing it atomically. Each person retrieves their order with a token, and the database controls who can change it.

Result

The team can choose dishes, review totals and edit selections while ordering is open, with a shared summary to coordinate the order.

Inside SanrioGang Archive: decisions and development

The challenge

Give the group a space of their own to bring together their music, images, and memories.

The response

A digital archive bringing together the group's songs, photographs, and fragments with a distinct identity.

The design

A collage aesthetic built around the group's logo, with galleries, video, and navigation adapted for mobile.

Professional experience

— present

Bitbox / IKEA

Software Developer

Since 2025, I have worked on internal applications, automation and data, while laying the foundations for AI agent adoption in the department.

  • AI-powered support analysis

    I built a tool to visualize helpdesk statistics, query the data through AI agents and automatically categorize tickets with LLMs. I designed its PostgreSQL data model, normalized to 5NF, and carried out database maintenance and management.

  • Development with agents

    I designed an agent harness and an agent-assisted development workflow, laying the foundations for their adoption in the department.

  • Data processes at scale

    I refactored critical SQL queries for generating and sending statements to hundreds of thousands of users each month.

  • Quality built into development

    I introduced testing practices to prevent regressions and CI/CD with mandatory tests and formatting checks. I automated code conventions with Git Hooks and Husky.

  • Application modernization

    I rebuilt an application with Next.js and React, updating the interface and fixing existing security vulnerabilities.

  • Backend renewal

    I worked with two other developers to rewrite an application's backend and central database, reducing years of technical debt and improving maintainability.
