Overview
In April, transferred to the Eight division. Eight is a business card management app aimed at eliminating paper business cards. Joined the iOS app rebuild project. This project aims to rewrite the complex, 13+ year-old codebase from scratch to accelerate development. I joined in the middle of the project.
Description
Activities in this project are described in two parts:
things learned throughout the year and features implemented.
The year's key learning was how to build features that are easy to discard.
This was the most valued principle in the rebuild project and had a significant impact
on me. To practice it, I deeply studied two books:
Writing Skills for Scientists and Engineers and
The Art of Readable Code. Reading these not only helped practice building
disposable features but also improved the accuracy of AI-generated output and served as
a defense against ambiguous AI results.
