I want my audience to get the idea of the cost of Javascript and how it can help on
improving the Time to Interactive metrics, and users satisfaction.

Speaker bio

I have five years experience as an engineer and have been working in startup company and also big companies such as IBM, Rakuten. Now, I’m working as a frontend engineer in Mercari, which is the first Unicorn company in Japan. I think I’m the best person to take this session because I came from business background (master degree of business in U.S) but also passionate about programming, so when I do programming, I’ll always think how to align technology with business goal. Other than that, I feel like most of frontend engineer only knows how to create application but reluctant to dig into what happens under the hood, which may do damage to the whole web world in terms of speed of the webpage, accessiblity...so on and so forth. As a result, I’d like to get into things under the hood to help engineers make better decision and make the web a better place.
