I Built an AI Portfolio Chatbot Without RAG - Here's How

Just launched my website with an AI chatbot built into the homepage 🙂

Ask it about my experience, skills, or what I've been working on. It streams responses in real time, running on GPT-4o-mini with plain context injection (I wrote about how it's built on the blog).

The site also has:

• Interactive demos
• A blog where I'll be writing weekly about system design and engineering

Sometimes the simplest architecture is the right one.
