Freelancer profile translated to English.
Back to original languageAbout Merwan
I help startups and SMEs increase their production capacity without hiring, by automating administrative tasks, support, and operations: email sorting, document processing (OCR), follow-ups (email/WhatsApp), chatbots/RAG, and back-offices.
What I deliver:
• Inbox & Email Ops: sorting/prioritization, extracting info from emails + attachments, creating/updating files, drafting replies, follow-ups, escalations, tracking blocked cases.
• Document Processing (OCR): invoices/contracts/proofs of identity → field extraction, quality checks, "to validate" queue, archiving, and export to your tools.
• Chatbots & RAG: assistant that answers from your documentation (PDF/KB/Drive) + "administrative" chatbot that collects info and triggers actions (ticket, status, follow-up).
• WhatsApp & Mailing: confirmations, reminders, missing documents, case status, onboarding/follow-up sequences based on events (with stop conditions).
• Back-office / dashboard: custom interface (statuses, filters, exceptions, exports, actions) to make automation manageable by the team.

AI-powered Order Automation SaaS PlatformAGRICULTUREMay 2026 - June 2026I designed and developed a SaaS platform that transforms natural language orders (SMS, WhatsApp, email) into structured purchase orders in the client's ERP. An AI agent understands the message, identifies the customer, checks the catalog, suggests alternatives for out-of-stock items, and only involves humans in cases of genuine doubt.- AI Order Taking Agent: reliable structured extraction (constrained JSON output, model + fallback), capable of reading disordered orders and normalizing them against a catalog of hundreds of items.
- "AI extracts, code decides": every critical decision is deterministic and tested, covered by a replayable test harness, whereas a simple LLM call would be unpredictable in production.
- Matching and availability management: product recognition by taxonomy and synonyms, automatic alternatives for out-of-stock items, human escalation only for ambiguous cases.
- Real-time multi-channel: unified SMS, WhatsApp, and email, ERP integration, nightly consolidation of needs and automatic sending of supplier orders, managed from a web console.
- Custom Telephony: a 4G communication box (Raspberry Pi + cellular module) hosts the client's mobile line, coupled with a softphone developed for their phone. The merchant continues to make and receive calls and messages normally, and sees the system-sent SMS in real-time. No change in usage, no change of number.
- Controlled Costs: AI processes tens of thousands of orders per year for a few tens of euros, and telephony runs on a fixed plan (~€10/month) with no per-message billing.
- Office et vousRedesign of PandaDoc System and Automation of Domiciliation ContractsMay 2026 - May 2026End-to-end automation of a subscription + electronic signature process (PandaDoc, FastAPI, Microsoft 365)For a business domiciliation company, I transformed a manual subscription and a flawed signature setup into a 100% automated tunnel, from prospect click to signed contract archiving.Key Achievements:
- Advanced PandaDoc API Integration: complete mapping of the platform's internal API to generate and send documents without consuming paid public API credits; essential for a cost-controlled public visitor journey, where the standard solution would have charged for each document.
- Automation to Microsoft 365: Microsoft Graph integration (OAuth, multi-account OneDrive) automatically archiving each signed contract and its supporting documents, sorted by company — without any paid third-party tools like Make/Zapier.
- Custom Backend (Python / FastAPI, Docker, HTTPS) orchestrating the entire cycle: document generation, signature with phone validation, auto-generated domiciliation certificate, client email sending (deliverability 10/10, SPF/DKIM/DMARC), and automatic incident monitoring.
- Contractual file reliability through business logic: redesign of the file in PandaDoc with fields that prevent errors; exclusive package selection, integrated proof of deposit collection within the document (no more reminder emails), sequential signatures client → manager.
Result: a self-operating process, automatically filed contracts in Microsoft 365, zero recurring automation costs. - Godel TechAutomation & Integrations Expert (n8n) — Process, Data & OpsJuly 2025 - Today (1 year and 1 month)Paris, FranceDevelopment of a tool that automates RGE processes for artisans: information centralization, document collection, checks, follow-ups, and status tracking.I have also automated service provider management processes for companies with many stakeholders: invoice generation, validation, reconciliation, and payment triggering, with traceability and exception management.Centralization and automation of spa operations: reliable scheduling, better coordination of staff, fewer omissions/errors, and a smoother customer experience (confirmation, reminder, payment).

Merwan immediately understood the problems and applied the necessary corrections efficiently and seriously. Very available, attentive, and technically competent, he quickly resolved errors that directly impacted my contracts and my business. A smooth and reassuring collaboration from start to finish.
