<p>Tide - a popular financial services platform in the United Kingdom with ambitious plans for global expansion. Over the course of several years, we were developing our mobile applications using native technologies. Facing scalability issues when aiming to enter new markets, platform inconsistencies, and limitations of our current solution, we decided to rebuild our products using Flutter. Flutter is a relatively young framework from Google for building cross-platform applications with a shared codebase.</p> <p>In this presentation, we will share the fundamental transformation our product went through in less than a year. We will discuss how we switched iOS and Android developers to Dart and Flutter, transitioned over a million lines of code to a new technological stack, and released a new version of the product for hundreds of thousands of users. We will highlight the challenges we encountered, the solutions we implemented, and the lessons we learned from this transformation.</p>

Let's talk about the complexity of modern frontend applications and the challenges facing contemporary development — security, performance, accessibility, and other non-functional requirements that a front-end developer must take into account while developing their application in 2023.

In this talk, we look at situations where TypeScript fails badly and learn why things have to be that way. We talk about trade-offs, workarounds, and ultimately solutions for all the damn, terrible lies we tell ourselves when using TypeScript.

This talk will be about how Unit built White-Label UI Components in React while making them completely native. We will discuss rendering React in Web Components, communication with them via native JS events, and the modularity of each Component.

During the discussion, we will dive into the world of Software Architecture, and discus best practices and current trends with experts.
