Back to original languageAbout Arthur
You're wasting time on repetitive tasks or your leads aren't qualified?
I automate your processes (ops, sales, support...) with AI and robust workflows to save time, reduce errors, and boost revenue.
🔧 What I do
- Advanced AI Workflows : agents (OpenAI/Claude), RAG, OCR, document generation, etc.
- Automated Prospecting & Nurturing : targeted scraping, AI scoring, multichannel sequences (email/LinkedIn), always up-to-date CRM.
- Integrations & APIs : Make/n8n + webhooks/REST/JSON, synchronization between your tools (CRM, ERP, accounting).
- Documentation & Transfer : you stay in control (guides, Loom, diagrams).
🌟 Why me?
- More than a “maker” : ex-fullstack dev (React/Node). I can go beyond no-code limits and design scalable & maintainable architectures.
- Already a founder : I created cold-boost, a 100% AI-automated cold calling SaaS.
- Business Vision : finance background ⇒ focus on KPIs, operational costs (Make ops), ROI.
🚀 Quick Examples
- B2B Prospecting Agent : collection + AI scoring + auto outreach → continuous qualified pipeline.
- Accounting/Admin Back-office : document sorting, AI extraction, auto-archiving & signing.
- Customer Support : AI agent connected to your knowledge base, escalating only complex cases.
⚙️ Method
- AI Audit
- Implementation & Testing (fallback, monitoring)
- Documentation & Training
