Piotr is a full-stack developer with seven years of experience who understands that code is primarily a tool for businesses to achieve their goals. Thanks to his product-owning experience, he can create zero-to-one products and balance trade-offs between the quality of underlying technology and delivery speed. With that approach, he was one of the key contributors to the success of cloud-based web applications with hundreds of thousands of simultaneous users or millions of IoT devices.
