As part of the Polygon Hackathon, I led the end-to-end design of "Open Meetup," a decentralized platform enabling participants to create, interact, and engage in events through micro-transactions. This project required a full-cycle design process, including brand identity creation and all digital visual materials. As a result, “Open Meetup” ranked among the Top 10 Projects out of 5,400+ participants, qualifying as Winner in its category with recognition from the hackathon jury.
