Role: Full stack丨UI/UX Designer
Duration: 2023 (March - June )
Chattnoww is a web application that designed to let users meet new friends, communicate with people, create groups and invite people easily. Our purpose is to provide a secure, friendly, and enjoyable chatting experience for every user without any cost. We also specializes our application for the in-person scenarios by utilizing geolocation services.
In today’s digital-first world, most chat applications are designed either for long-term communication (like messaging apps) or ephemeral conversations (like dating apps or event-specific platforms). However, there’s a gap for a lightweight, real-time chat platform that caters specifically to in-person group scenarios, such as study groups, social events, or campus communities.
