Software engineer with an M.Eng. in Computer Science from École des Mines de Saint-Étienne, previously at Murex and Diverta. I specialize in full-stack architecture with a keen interest in backend development primarily using Rust axum, Spring Boot and also on developer tooling and measurable performance. Notable wins include building a 1.3 GB/s zero-copy parser of a format called TOON similar to JSON and cutting environment patching delays from 5 hours down to 20 minutes at murex.
Software Engineer Intern @ Murex (Apr 2026 – Sep 2026, Paris)
Built a portfolio optimization prototype end to end for murex. I used Java / Spring Boot / Python for the back end and TypeScript for the front end. The python service was deployed as a micro service using GRPC.
Outside the scope of my internship, I worked on:
| What | Before | After |
|---|---|---|
| Rust CLI tool that smartly patched existing deployed environments instead of building new ones from scratch | ~5 hours via CI/CD | 20 mins, mainly to restart the new services. |
| Concurrency bug in a production API | A method fully synchronized just to check whether a Future was consumed, forcing the service single-threaded |
Traced, documented, and unblocked |

Independent project, March 2026
Zero-copy parser for the TOON format. Reused the 2 stage approach pioneered by Lemire and Langdale and modified it for the indentation based format: TOON.
Co-founder & full-stack engineer, 2026
A platform that helps international students settle abroad: housing, connections, and local integration. I designed the back end in Rust / Axum, including a real-time messaging system written from scratch over Socket.IO and an interest-based matching algorithm that pairs students with peers. Three clients ship against it: two Next.js 16 web apps (an admin console and a homeowner listing portal) and a Flutter app for students.
Founder & developer, 2024 – 2025
Cross-border marketplace connecting proxy buyers with customers who want rare or hard-to-source products. Next.js 15 / TypeScript front end, Spring Boot back end on AWS, Stripe and Wise for payments, WebSockets for messaging.
Software engineer intern, June – Sep 2024
Headless CMS with 6,000+ customers, including Mitsubishi, Capcom, and the University of Tokyo. I migrated core UI components from Vue 2 to Vue 3 (Composition API), added TypeScript support for user-defined functions with sandboxed execution in Deno, and designed a multi-provider CAPTCHA layer that runs Cloudflare Turnstile alongside reCAPTCHA.

| 🚀 | Beat the official Rust TOON parser by up to 10x with simd-toon |
I'm looking for a full-time software engineering role starting late 2026, ideally where back-end performance, developer tooling, or applied AI matters. I'm also happy to talk about Rust, agent architectures, or why your CI pipeline is slow.
