Håkon Wium Lie proposed Cascading Style Sheets (CSS) while working with Tim Berners-Lee at CERN in 1994. Along with Bert Bos, he developed a set of ideas for web style sheets into a implementeable W3C Recommendation. As CTO of Opera Software he shepherded Opera's implementation, and he proposed the Acid2 test to ensure that all browsers complied. He is the chairman of YesLogic, which makes the Prince CSS-to-PDF formatter. In 2015, Håkon sailed from Lima to Easter Island on a balsa raft, making sure the world-wide web is truly world-wide. He holds a MS from the MIT Media Lab, and a PhD from the University of Oslo.

Hi, my name is Charity, and I am professionally caremad about computers. I am an operations and database engineer and sometimes engineering manager. Right now I am the CEO and cofounder of Honeycomb, where we build observability for distributed systems. (“Monitoring” doesn't have to be a dirty word; give us a try.) Until recently I was a production engineering manager at Facebook. I spent 3.5 years working on Parse (both pre and post-acquisition by FB). I also spent several years at Linden Lab, working on the infrastructure and databases that power Second Life. I am the co-author of “Database Reliability Engineering” by O'Reilly. I was a classical piano performance major in college, but dropped out because it turns out I prefer not being dirt poor. I have been building systems and engineering teams ever since. I love startups, chaos and hard scaling problems, and somehow I always end up in charge of the databases.

Hi, I'm Willian, I've been earning money doing FrontEnd since 2007 although I work on IT since 2004. I like to call myself as JS formatter and CSS tweaker since I don't really care about job titles. I'm very concerned about company culture, therefore, I love to be and shape the company I want to work by leading by example and giving nice and constructive feedback. Tech-wise, I'm a framework agnostic more than that, I prefer Web standards over frameworks.

At Slack, we use one JavaScript codebase to build a multi-threaded desktop application, routinely interacting with native code. Managing large JavaScript codebases is challenging - we need a guarantee that the individual pieces fit together. In the desktop world, a small mistake is likely to result in a crash. To that end, we adopted TypeScript and quickly learned to stop worrying and love the compiler. See an introduction and a detailed account of porting a large code base, learn why exactly TypeScript is so popular, what the downsides are, and how you would slowly adopt it in your development.
