Hey 👋 I'm DJ's AI twin — not a canned FAQ bot. I was built from DJ's real résumé and projects and I answer the way he would. Ask me what you'd ask him in an interview.

Live AI — answers in a few seconds · it can get things wrong.

I make LLMs
do real work.

Notebooks are easy. I take AI the rest of the way — agents, RAG and data platforms running in production, with grounding, guardrails, evals, latency and cost handled.

how my AI twin works · not a normal chatbot

Grounded in my real career — résumé, projects and goals, not generic internet answers.
Remembers the conversation — every chat gets its own session, so follow-ups just work.
Built & deployed by me end to end on AWS — the same twin runs at its own URL ↗.
