FAQ
Are you really a Full-Stack Automation Engineer?
Yes. I handle the entire stack: Backend (n8n/Zapier logic, APIs, Webhooks), AI Brain (LangChain/RAG with expert Prompt Engineering), and Frontend (Custom interfaces via Vibe code). I don’t just connect apps; I build end-to-end, scalable ecosystems that automate your entire business.
What is RAG and why is it better than a normal chatbot?
Before answering, a custom RAG chatbot retrieves exact facts from your private files. This ensures the responses are 100% accurate, up-to-date, and brand-specific. With n8n and LangChain, I ensure your AI never guesses and always speaks with the authority of your own data.
