Features
Speakers
Orta is a developer/designer who works on web-powered games. Prior to that, he worked on the TypeScript team in Microsoft. He has a decade of open source contributions ranging across many eco-systems, helps maintain a dependency manager for iOS, built Danger in many languages, contributes to working groups like GraphQL and in core teams like Jest, Svelte and React Native. You've probably seen his open-source design work in the React/TypeScript ecosystem.
Dan Vanderkam is the author of Effective TypeScript (O'Reilly 2019) and a Principal Software Engineer at Sidewalk Labs. He previously worked on open source genome visualizations at Mt. Sinai's Icahn School of Medicine and on search features used by billions of users at Google (try "population of france" or "sunset nyc"). He has a long history of working on open source projects, including the popular dygraphs library and source-map-explorer, a tool for visualizing JavaScript code size. He is also a co-founder of the NYC TypeScript meetup and blogs at effectivetypescript.com. When he's not programming, Dan enjoys playing bridge and climbing rocks near his home in New York's Hudson Valley.
Mark Erikson is a software engineer living in southwest Ohio, USA. Mark is a Redux maintainer, creator of Redux Toolkit, and general keeper of the Redux docs. He spends much of his time answering questions about React and Redux anywhere there's a comment box on the internet, and usually hangs out in the Reactiflux chat channels.
Mark is also disturbed at the number of third-person references he has written in this bio.
Working closely with customers designing & building TypeScript solutions. Recently a Lead Engineer at Snyk working on extending our current languages offering by introducing new languages and language-specific concepts into our system in the shape of libs, parsers and microservices. When not coding I like to spend my time hanging upside down doing circus things.
After working as a science teacher for a few years, Sylvana transitioned into software engineering as a means to provide a quality education to all learners. She began her career as an apprentice at Codecademy and is now a software engineer at the company. During her time at Codecademy, she has gained experience with React, Next.js, and Typescript and has led initiatives like the tech reading club and dev workshops.
Daniel is on the Framework team at Nuxt - previously CTO of a tech startup. In his open-source work has a particular focus on serverless functions, TypeScript, and the Composition API. He's based in the North East of England where he lives with his family, three cats, and a dog.
I am a developer in the JavaScript infrastructure team at Bloomberg where I work on JavaScript and TypeScript tooling for internal developers.
I am very passionate about TypeScript and try to help others by answering TypeScript questions on Stack Overflow. I am currently the number 3 answerer for the TypeScript tag. (https://stackoverflow.com/tags/typescript/topusers).
I am also a TypeScript compiler contributor, where I recently contributed the implementation of ES class private methods and private static members. (https://github.com/microsoft/TypeScript/graphs/contributors).
Nathan is an engineer on the Typescript team, working on Javascript support and open source community, including Definitely Typed. He has a Ph D in linguistics from the time he made a machine classify Swedish dialects using syntax. The common thread is that Nathan loves writing programs to understand messy linguistic systems. For fun, Nathan enjoys video games, a wide variety of reading, and hiking with his family around the Pacific Northwest.
Ashley is a software engineer at Bloomberg in the Trading Analytics team. He has been using TypeScript since v1.8 and contributed to the TypeScript implementation of the new 'Ergonomic brand checks for private fields' syntax. He is also a Bloomberg TC39 delegate currently working on the 'Change Array by copy' proposal.
Ondrej is a Jamstack enthusiast focused mostly on React and Vue-based tools. As a Developer Evangelist at Kontent by Kentico, he constantly stays connected with in-house and partner developers, which brings him closer to many interesting digital projects built with various tools. Always interested in problems that everyone claims have no solution, Ondrej enjoys building the architecture of components or applications and figuring out how all parts fit together. He also creates videos and speaks at conferences and podcasts.
Loren is a Language Runtime Engineer at Temporal, maintaining the TypeScript runtime. They also wrote a book on GraphQL (The GraphQL Guide) and spent over a decade doing full-stack web and mobile development. They love swing dancing and authentic relating, and they secretly miss CoffeeScript π

Kelli is a fullstack engineer based in Seattle, WA and working at Sourcegraph to build tools that improve how we work with code. When she's not consuming boba, aka bubble tea, you can usually find her evangelizing TypeScript at yet another developer meet-up, advocating for women and underrepresented folks in tech, or nagging her teammates to update the docs.
Lenz Weber works as a FullStack developer at Mayflower GmbH in Germany, where he works mostly on a TypeScript, React, Redux and Postgraphile stack. He is a maintainer of Redux Toolkit and if he's not currently trying to summon elder gods with weird TypeScript incantations he can usually be found in the Reactiflux Discord or on StackOverflow answering questions on Redux usage.
