Back to original languageAbout Raphaël
Hello there ! 👋
If you're reading this, it means I've managed to capture your attention. Let me describe myself in 3 words: Software Engineer, Centralien, freelance (yes, that's 4 words).
What does that look like in practice? 4 years building systems from scratch:
🔹 Fynd (founding eng) — I designed and delivered the entire platform (REST API + front + infra) + the ETL pipeline + embeddings + vector search: 2M+ products, 150+ marketplaces.
🔹 YiZo (my solo B2B SaaS) — from architecture to customer support, including sales: 1M€+ in orders processed, 10+ recurring clients.
🔹 Eiffage — Production APIs and data pipelines: 100k+ invoices/year analyzed.
My comfort zone: backend (Python/FastAPI), applied AI (LLM, embeddings, STT/TTS), and the full loop from architecture to delivery to customer feedback. I enjoy designing and shipping a project end-to-end.
The rest — your needs, your context, what we can do together — I'm here to discuss it.
See you! 🔜
