Description

I am Mehdi, a freelance fullstack developer specializing in n8n automation and AI agents. I help SMEs, agencies, and scale-ups replace repetitive tasks with automated workflows that run 24/7.

Background: 3 years of apprenticeship in fullstack development (SMILE on Engie + Crédit Agricole projects, CILcare on medical SaaS), Master's degree from EPSI Montpellier (2025), full-time freelance since June 2025.

What I do:

n8n Automation (self-hosted or cloud) — workflows that connect your tools (Google Sheets, HubSpot, Gmail, Slack, CRM, APIs). Turnkey setup, monitoring, documentation, training.

AI Agents and LLMs — internal chatbots, document classification, lead enrichment, content generation. OpenAI, Claude, Mistral. Orchestration via n8n or custom code.

Fullstack Development — Next.js/React for front-end, NestJS or Django for back-end, PostgreSQL or Supabase for database. When automation is not enough.

Self-hosted Infrastructure — deployment of n8n, vector databases, local LLMs on VPS (Hostinger, Hetzner). Docker, reverse proxy, backups.

Recent Projects:

- US Meal Delivery Operator (Francisco Meals): n8n workflows Google Sheets ↔ Circuit/Spoke API for 2 depots, fuzzy matching, auto PACE invoice generation. ~5h/week saved.

- Zeumatic: Multi-tenant meal delivery SaaS for the elderly. Java 21, Spring Boot 3.2, Next.js 14, PostgreSQL 16, Docker on Hetzner VPS.

- B2B Prospecting: n8n + Apify + GPT-4 pipeline, Google Maps scraping, personalized emails, HubSpot. 100+ qualified leads/hour.

- CILcare (apprenticeship): Clinical data analysis SaaS, Django REST + React/Next.js/TypeScript, Docker + CI/CD.

I am pragmatic. No AI if n8n is sufficient, no development if Google Sheets already does 80% of the job.
