I'm a web browser developer worked at Naver Whale Browser, and Brave Browser . And I'm also a Chromium committer. I'm not hired at this moment, but eager to working on developing web browser features.
In case you're interested in contributing to Chromium, I can help you happily - Please email me.
Also I'm trying to share what I know here - https://www.youtube.com/channel/UCgXGlah7QZBpZRbt9qg_8CQ
Might take long for update though 😊
