Rapid Prototyping with Streamlit & Gradio

Rapid Prototyping with Streamlit & Gradio

Turn Python code into interactive AI apps in hours, not weeks

The gap between building a model and delivering something people can actually use is where many AI and data projects stall. Streamlit and Gradio solve this problem by allowing developers to create interactive, web-based applications directly from Python code, without traditional front-end complexity. These tools have become essential in modern AI teams for rapid prototyping, internal demos, proof-of-concepts, and even production-ready tools.

This two-day course focuses on practical, industry-driven workflows that show how professionals rapidly move from notebooks and scripts to usable applications. The instructor brings over 30 years of industry experience and teaches proven patterns used in real AI teams, avoiding academic abstractions in favor of what actually works under real constraints.
