Experience

Sweepbright

http://www.sweepbright.com/

这是一款比利时的B2B应用程序，专为房地产中介提供自动化服务. I joined the project at the start of the scale-up phase. iOS应用程序正在运行，但存在许多问题，包括代码和设计方面.

我的目标是清理应用程序，使其更主流，并在此过程中修复主要的代码问题. 这一努力使我们能够以更快的速度进入法国市场, for which a clean and polished iOS app was one of the main movers.

主要的代码问题是未定义的体系结构，这使得状态很难确定, heavy reliance on a very outdated third-party library, and a general lack of defined code-style and best practices.
