01Introduction
About.
'm a senior iOS engineer with 12 years of experience in various fields such as video streaming, IoT, online travel agency, and more. Thanks to those high-variety backgrounds, my iOS development expertise ranges from UIKit to low-level C implementation. My main focus is leveraging industrial practices and teamwork to provide timely, high-quality mobile-first solutions.
I'm also passionate about contributing to the community, leading me to become a writer for the Swift & iOS online publisher AppCoda (https://www.appcoda.com.tw) and the organizer of the Tokyo-based meetup WebHack (https://webhack.connpass.com/).
