I already have a React-based mobile app live in the stores, but the first release was built quickly and now needs polish and a handful of fresh, user-facing additions. Because I’m bootstrapping a small startup, I’d like to give an enthusiastic junior developer a real product to sink their teeth into while working side-by-side (remotely) with our senior engineer for mentorship and code reviews. Here’s the current focus: • UI improvement: tighten up navigation flow and overall UX so screens feel intuitive, consistent and snappy on both iOS and Android. • New feature roll-out: – Push notifications (Firebase Cloud Messaging already wired for basic keys). – Social media integration for login and light content sharing. – Payment flow ...
