I'm Julien, a senior software engineer in Abu Dhabi. I build real-time operator UIs for humanoid robots at TII, on top of 5 years shipping pixel-perfect products with React, Next.js and Angular. Fast, precise and reliable is the standard, not the stretch goal.
From humanoid robot consoles to defense platforms: a few things I've shipped.
Real-time operator interfaces for humanoid robots at TII: live telemetry, monitoring and control.
Real-time 3D mission views fusing satellite, radar and drone imagery. Details under NDA.
Frontend of an industrial cybersecurity (XIoT) platform: securing and monitoring connected industrial assets. Set the component standards and drove the UI/UX R&D.
Multi-step application process for a leading private higher education group.
Open source package that fixes nine default weaknesses in how Claude Code runs: delegation, model-tier routing, testing discipline, cost, and more.
Beyond client work: products I design, ship and operate end to end, live in production.
Collect video testimonials effortlessly.
Send a link, clients record in the browser, no app install. Whisper transcribes every video and GPT turns it into ready-to-publish marketing copy, with branded collection pages, a moderation dashboard and an embeddable Wall of Love.
Building real-time operator interfaces for humanoid robotics in Angular and TypeScript. Led a staged Angular 17 to 21 migration and rolled out a shared design system across the platform.
Led projects like Succès Scolaire, EGF and Queer Tech, building a reusable Next.js 15 / React 19 / Sanity starter adopted across the agency. Drove CI/CD with Vercel and GitHub Actions and integrated AI tooling (Claude Code, Cursor).
Built a real-time geospatial platform for a defense client: interactive 3D scenes (WebGL / Three.js) fusing satellite, radar and drone imagery, with live positions streamed over WebSocket and MQTT. Details under NDA.
Built the frontend of an industrial cybersecurity (XIoT) platform. Defined component standards, drove UI/UX R&D, and introduced secure practices like Nordpass across the team.
Led the frontend of a fintech project: implemented refresh-token authentication, hardened app stability, and migrated components from Vue 2 to Vue 3.
Built a SaaS app for sales presentations: back office, Firebase authentication, real-time data sync, and automated final-report generation.
Built the new application-form journey for France's grandes écoles (INSEEC, Sup de Pub): a styleguide, full component library, routing, and API integration.
Built Catch'up, a career-support web platform, in React: reusable component library, styled-components theming, and close API integration with the backend team.
Designed and shipped the catalog site for France's leading wedding dress distributor: brand guidelines, Figma mockups, WooCommerce, Elementor integration, and a client area.
Built a marketplace to revalue dormant stock across Auvergne-Rhône-Alpes: brand identity, Figma mockups, Firebase authentication, and a company dashboard.
I build scalable platforms with obsessive attention to detail.
I'm Julien, a senior software engineer based in Abu Dhabi. Across 5 years and 10 roles in France, Canada, and the UAE, I've shipped everything from real-time operator UIs for humanoid robots to scalable platforms and pixel-perfect products with React, Next.js and Angular.
The stack I ship with every week, hardened on production systems.
Feedback from earlier React and frontend engagements.
Julien is an excellent front-end developer. We collaborated on many React development projects and it went really well. Professional and rigorous, he is a pleasure to work with. I highly recommend him.
I warmly recommend Julien for any project that calls for React expertise. He delivered strong results and his technical skills are excellent. I am very happy with this collaboration, especially the flexibility he showed. I would not hesitate to recommend him again.
I am delighted to recommend Julien Tavernier for his work as a freelance developer. I had the pleasure of working with Julien on several web projects, and I have to say his ReactJS expertise is impressive. Julien has a passion for web design that shows through in his projects and his relevant advice.
Real-time interfaces, scalable platforms, or a site like this one: whatever you're building, you get the same standard. Fast, polished, shipped.
