You will get high quality automation in n8n.
Rising Talent
Project details
As an electrical engineer and software developer, I understand both technical systems and AI integration, making me ready for complex automation challenges.
I create n8n workflows that connect multiple services, APIs, and AI models. Experience creating APIs, LLM fine-tuning, and custom AI applications means I build automations that go beyond basic triggers. I develop workflows that process data intelligently, make decisions using AI, and adapt to your specific business needs.
My technical background includes Python, TensorFlow, API development, and database integration. I work with various platforms and understand how to connect different systems through n8n's powerful automation capabilities.
What you get:
Smart n8n workflows tailored to your processes
API connections between multiple platforms
Error handling, testing, and documentation.
Integration with databases, web services, and AI models
Based in Berlin with 3+ years developing AI applications and automation systems. Fluent in English, German (B1), native Spanish.
The automations I deliver are tested, reliable, and ready for production use.
