About Réda

Senior React developer and former CTO, I help product teams deliver quickly and effectively — not just code, but working products. React is my foundation (web and mobile with React Native), backed by Node.js, GraphQL, and PostgreSQL; I remain primarily product-oriented and adapt to your stack.

My real differentiator: AI-augmented development. I don't just use assistants — I build LLM-driven internal tools. At Qonto, I designed a VSCode extension that automated an Ember→React migration using dynamic prompting and pattern detection. Co-founder & CTO of Jules AI (acquired by MineHub in 2025), I bring CTO-level technical judgment with a real delivery capability.

I work remotely and on-site on: React/React Native web and mobile applications, Node/GraphQL back-ends, AI agent and LLM feature integration, code refactoring and migration, technical guidance.

Experience

  • Jules AI
    Co-founder & CTO
    January 2018 - October 2025 (7 years and 9 months)
    Paris, France
    Co-founded the venture in 2018 (as Harold Waste) and grew it into Jules AI — an AI-driven commodity & trade-risk management platform automating the buying, selling and trading of recycled metals. Built the product and engineering organization from zero as CTO, leading a globally distributed team (Paris, Toronto, Pune); owned architecture, stack, hiring and roadmap. Architected the platform on TypeScript / Node — Express, Apollo (GraphQL) Server, Knex and PostgreSQL, containerized with Docker; React on the front end. Scaled it to process ~2 million metric tons of scrap in 2024, cutting traders' processing time by up to 7×. Led the company to a successful exit: acquisition by TSXV-listed MineHub Technologies in 2025.

  • Qonto
    Freelance Senior React Engineer
    April 2025 - October 2025 (6 months)
    Built a VSCode extension automating a large-scale Ember → React migration, slashing manual conversion work. Designed a reusable "pattern" system — codified prompts (e.g. form handling) that the tool auto-detects per page and applies via LLM-driven dynamic prompting. Paired senior React expertise with applied AI tooling to accelerate the migration.
