Freelancer profile translated to English.

Description

Graduated engineer (ENSTA), I design automation systems that save ops, finance, and HR teams days of manual work each month.

For 3 years, I have been supporting startups and scale-ups (Sparteo, Flexliving, BNP Paribas, Polyconseil...) on their high-stakes operational automation projects:

🔧 What I do concretely:

Complex n8n / Make workflows (anomaly detection, alerts, automatic corrections)

Integration of AI into business processes (document analysis, classification, extraction)

Automation of billing and financial flows (Stripe, Pennylane, Revolut)

Multi-tool synchronization (HubSpot, Notion, Directus, Airtable, Xano...)

Redesign of scalable internal tools (Xano + WeWeb, FlutterFlow, Glide)

💡 My approach:

I don't just deliver an isolated workflow: I map out the process, identify friction points, and then build a sustainable architecture. Documentation and maintenance are included by default.

📊 Examples of results:

Sparteo: 30+ quality control workflows, up to 5 days/month saved per department

Flexliving: 100% automated tenant journey (payments, invoices, reminders)

Datatopia: invoice analysis tool with custom AI model on Azure

🛠️ Main Stack:

n8n · Make · Xano · WeWeb · Notion · HubSpot · Stripe · Azure AI · OpenAI API · Python (occasional)

Available for 1 to 5 days/week assignments, remotely. I can work with French/English and Portuguese speaking teams.
