Back to original languageAbout Alexandre
Product Engineer with 16 years of real-world production experience — including 5 years as the sole frontend developer for lemonde.fr and télérama.fr, two of France's most demanding editorial sites in terms of performance, SEO, and volume.
I work on projects where execution quality matters: complex interfaces, maintainable frontend architectures, and integration of AI tools into existing products.
My approach is not that of a developer who just delivers pages. I understand the product, anticipate technical constraints, and work with complete autonomy from scoping to deployment.
What I build
Web Development Side: React/Next.js applications, frontend architecture redesigns, component systems, Core Web Vitals performance, technical SEO. I work on both existing codebases and projects from scratch.
Automation and AI Side: n8n workflows, LLM API integration (OpenAI, Claude), simple AI agents, data processing pipelines. I help teams and SMEs connect their tools and automate their processes without unnecessary complexity.

Le Monde — complete frontend redesign, 50M+ visitors/month, real-world production performance and accessibility.
Télérama — complete rebuild of télérama.fr, custom PHP/Phalcon/Volt architecture.
Main Stack
JavaScript, TypeScript, React, Next.js, HTML/CSS, PHP, Astro, n8n, Supabase, OpenAI API, Figma, Technical SEO, Core Web Vitals.
