About

Software Engineer working with Node.js, TypeScript, and React. I also enjoy building with Python for personal projects. Software may not improve on its own, but it should at least be sustainable. I prefer to develop with software sustainability in mind. Experienced in developing a browser-based chat messaging SDK and an event tracking SDK for marketing measurement attribution. I've also built development environments, developed web services, and shipped products across multiple companies. Always looking for the right balance between fast delivery and high quality, and how teams and their members can grow together. Recently exploring prompt engineering and context engineering for AI-assisted development.
