Postbox is an online interface to work with a Freewrite devise, allowing to work with drafts, user profile, etc. My role and responsibilities were limited by short time on the project, lasting just several months. During this time, I actively contributed to developing a UI library for the project's redesign, then developed the new front-end application based on Next.js and the newly developed UI library. Near the end of my work, I had a chance to also work on introducing a subsystem for National Novel Writing Month (NaNoWriMo).
