Portfolio Web

Portfolio Web

A modern portfolio website built with Next.js, Tailwind CSS, and n8n-powered AI chatbox.

More details

This website is a showcase of my software engineering projects and skills. The frontend is built with Next.js and Tailwind CSS for a fast, responsive, and beautiful UI. The backend leverages n8n for workflow automation and API orchestration. A standout feature is the AI-powered chatbox, which uses Retrieval-Augmented Generation (RAG) and Gemini API for intelligent, context-aware Q&A. n8n acts as the backend orchestrator, handling secure communication, workflow automation, and connecting the chatbox to a knowledge base for accurate answers.

Key Features

  • Responsive design for all devices
  • Dark/light mode toggle
  • Optimized for SEO and performance
  • AI-powered chatbox (RAG + Gemini)
  • Backend workflow automation with n8n
  • Secure API orchestration between frontend and backend
