About

Hi! I am a Software Engineer @ Circle integrating critical fiat operations with our banking partners. Previously, I worked with internal infrastructures, and own several libraries that enable smooth business operations. Outside of work, I enjoy traveling, photography, video games, coffee, and cooking. All of which have greatly benefited from remote work. I also value in person connections and love to chat. Feel free to reach out!
