Alexandre Spindola

Currently contracting at a German real estate tech as Senior n8n Automation Engineer. Available for B2B engagements · EU Citizen · Based in Cologne 🇩🇪

🛠️ TypeScript and Node.js are my primary tools: NestJS and Hono for backend services, Vue/Nuxt on the frontend, and n8n when workflows need to be automated or AI needs to be orchestrated. Currently migrating legacy RPA (UiPath) to modern n8n + Puppeteer architecture.
