JavaScript has expanded far beyond the browser environment, now driving countless backend systems, APIs, and cloud services through Node.js, one of the world’s most extensively used runtimes. Maintaining the speed, security, and stability of such a vital infrastructure component poses a significant engineering challenge, with much of the work remaining unseen.
Rafael Gonzaga, a Principal Open Source Engineer at NodeSource and member of the Node.js Technical Steering Committee, has dedicated years to exploring performance and security layers of Node’s core, influencing the runtime’s overall direction. Rafael joins the program to discuss Node.js performance, the true nature of benchmarking, the trade-offs between speed and stability, and the implications of contributing to one of the world’s key open-source projects.

Josh Goldberg, an independent full-time open source developer, contributes to the TypeScript ecosystem. He focuses on projects that simplify writing better TypeScript, especially typescript-eslint, which enables tools like ESLint and Prettier to work with TypeScript. A regular contributor to projects like ESLint and TypeScript, Josh is a Microsoft MVP for developer technologies and authored Learning TypeScript (O’Reilly), an invaluable resource for developers transitioning from JavaScript to TypeScript. He frequently shares his knowledge at bootcamps, conferences, and meetups, discussing TypeScript, static analysis, open source, and general web development.
