About

Professional summary

I am a senior full-stack developer and designer with eighteen years of experience building web products for agencies, cultural organizations, and product teams.

I work across interfaces, backend systems, security, testing, accessibility, and delivery pipelines. I care equally about making products intuitive for users and making their underlying systems reliable when things fail.

My core technical background includes TypeScript, JavaScript, Java, Rust, PHP, Node.js, React, Vue.js, Svelte, Next.js, Spring Boot, and GraphQL. I have worked on high-traffic websites, collaborative tools, education platforms, video services, and clinical-trial software.

I have strong experience in application security and quality engineering, including web security, end-to-end testing, visual regression, and CI automation.

I also enjoy open source and independent product work. I maintain cargo-local-registry for offline Rust builds and am building Synapse, a local-first study application using Svelte, NestJS, Tauri, Rust, and CRDTs.

Alongside full-time work, I am completing the final year of a professional computer science degree at CNAM Paris.
