Two demos — an AI chatbot that knows my resume (with prompt caching, naturally), and an interactive view of the Tututor architecture I shipped.
Edge function, Claude Haiku 4.5, system prompt cached for ~90% cost discount on repeat questions.
Ask anything about Ubaidullah's experience, projects, or skills. The system prompt is cached, so replies are fast and cheap.
Hover any service to see who talks to whom. This is roughly the boundary I designed to keep teacher UX responsive while AI work happens behind the scenes.
