Tired of slow web apps with big data? Learn how Python & WebAssembly dramatically speed up browser data tasks. See a live demo: processing a large CSV client-side with Python (via Pyodide) & Pandas/NumPy. Witness a performance comparison and more.

Discover a game-changing approach to web performance! Learn how to leverage Python (compiled to WebAssembly) to process large datasets directly in the browser with incredible speed. We'll walk through a practical use case involving CSV data and compare the performance gains against standard JavaScript implementations. Get ready to unlock new possibilities for data-intensive web applications.
