• I help build Visual Studio Code, a cross-platform text editor built on web technologies. The majority of my work is publicly visible on GitHub (https://github.com/Tyriar).
• Being the first engineer in the team physically located in the US, I helped iron out a lot of the initial issues with working in a distributed team.
• Proposed integrating a terminal into VS Code and took it from an idea to one of the core features of the product. I contributed heavily to the open source project xterm.js as part of this, becoming a maintainer of the project.
• Implemented hot exit which backs up unsaved changes so the editor can be exited/restarted without a prompt or restored after a crash.
• Implemented deb/rpm packages and distributed them in signed repositories for easier installation on major Linux distributions.
• Improved and supported VS Code on Linux.
• Contributed to many external open source projects, most notably xterm.js (https://github.com/sourcelair/xterm.js) and node-pty (https://github.com/Tyriar/node-pty).
