In this talk, i'll show take you on a journey of e-commerce transformation - from a monolithic (and outdated) server-side rendered PHP app - into bespoke SaaS e-commerce platform that follows MACH standards. To do that successfully - we had to break some of the most basic “rules” of online commerce. We made the process asynchronous, with event-driven systems and react server components for one of the fastest experiences ever made. Because of that, our users can now go from from payment to order in 2 seconds - instead of half a minute.
