First commercial development experience. Entered into a huge, complex application development as a junior MERN (Mongo + Express + React + Node) developer. Worked on multiple frontend and backend improvements, including ActiveCampaign and BrainTree integration.

In a year became way more advanced in React, so easily settled on a lead frontend developer position. Suggested and implemented a lot of improvements, kept working on backend as well. Refactored (mostly rebuilt) the entire frontend, completed a huge redesign task
