Michał Pierzchala

Callstack

As app developers, builders, software architects, and designers, we’re used to shaping things the way we like. Bend the code to our reality. Often believing we have full control over our creation. But the reality is much more complex. Reality means talking to other people, and communicating needs and ideas. Michał is going to show you how this communication shapes and designs your products and code, how React fits into this picture, and how to take Conway’s law to your advantage.
