About me
Intro
I ship AI inside real products, not demos. The hard part was never the prompt, it's surviving real users. I take the whole layer: agents, RAG, integrations, guardrails, UI and backend. My conviction: deterministic code decides, AI reads the mess, a human rules. Home turf: fintech and finance ops. Ex-Pivot: shipped the approval flow and NetSuite. Founder of Neige and ledgerloop (open-source procure-to-pay agent). Available immediately, on-site in Paris or remote (full on-site works, hybrid too).

I build production AI tooling for finance and procurement teams: the unglamorous, high-stakes work. Invoice and contract automation, agentic approval workflows, and RAG that actually holds up in production. I own it from design to deploy, including the eval and guardrail layer most teams skip. Most "AI features" die as demos. I ship the ones that survive contact with real users, and real auditors. I work fast and stay close to the client: clear updates, direct communication, and turning messy business problems into systems that actually ship. Stack I usually reach for (and happy to adapt to yours): Next.js, TypeScript, Node, Supabase, Mastra for agent orchestration, and the major LLM APIs (OpenAI, Anthropic). It's a representative stack, not a constraint. I pick what fits the problem. Before founding Neige I built internal automation at Pivot (procurement fintech) that cut client onboarding time by 90%.
Founder
Jun 2025 - May 2026
1 year
San Francisco, CA, USA
I founded and built Neige: an autonomous AI agent platform that ran the full content-generation pipeline for brands, from ideation to generation to self-improving feedback loops, no human in the loop. I designed and shipped the entire system myself, from agent orchestration and RAG to the full-stack product (Next.js, TypeScript, Mastra, Supabase), taking it from an empty repo to a working autonomous pipeline. As founder I also owned the business side: outbound, discovery calls, and pitching the product directly to brands and agencies. I'm as comfortable talking outcomes with a non-technical stakeholder as I am shipping the system behind it.
