    • Developed and maintained internal web applications in a cross-functional Agile team with product owners in the United States, writing front ends in React and TypeScript over Node.js REST APIs and SQL databases. • Created and owned the main UI component used across all internal applications. • Won the company's internal hackathon with a dashboard that consolidated project financial tracking into a single view. • Reviewed peers' pull requests on GitHub and kept the CI/CD pipeline green so that every change went through the same automated build and deploy.

    • Developed front-end and back-end features for internal and customer-facing B2B web applications, using JavaScript, TypeScript, React, HTML, and CSS. • Built almost the entire front-end of the internal newsletter platform in React, HTML, and CSS, which the company used to write and send its internal communications. • Consumed REST APIs on the front end and handled loading, error, and empty states in TypeScript, which kept the application usable when a back-end service was slow or down. • Helped create and organize the project backlog with the team, so that each sprint started with the work already broken down and ready to be picked up.

    • Learned the project stack hands-on, writing Python and running containerized workloads with Docker and Kubernetes alongside senior developers. • Helped build a Private Cloud product written entirely in Python: a highly available and scalable application running its workloads on a Kubernetes cluster. • Participated in code reviews on Git and GitHub, for both an open-source platform and the company's proprietary software. • Fixed platform bugs and repaired failing unit tests, returning the build to green so the team could resume merging.
