file_01 // about

Five years turning ambitious specs into things that actually ship: multitenant architecture, internal tooling, APIs that hold up under real traffic.

I'm Yamil, a software engineer based in Paris. Over five years at Leaneous, I designed WordPress and Shopify sites for several clients, contributed to the front-end of Leaneous's own site in Vue.js (building out components and working across the UI), and improved the UI/UX of a React Native app, cutting its API latency by 25%. On the backend, I finalized and shipped the multitenant architecture behind an online art valuation platform, fixing every bug tied to the migration, built a NestJS API serving a 3,000+ reference product catalog, and automated supplier invoicing and lead qualification, cutting processing time by 70% and lifting qualification speed and quality by 80%.

These days I work freelance, open to missions and full-time roles across the Paris region. Native French, professional English (C1).
