I want to take Bijiman Busy’s mobile app from “nice to have” to “can’t live without” by weaving in three engagement-driving features: timely push notifications, real-time in-app chat support, and a rewarding loyalty program. The core app is already live on iOS and Android; what I need now is someone who can design, build, and fully integrate these add-ons without disrupting the current user experience. Push notifications • Create segmented, actionable messages (promos, order updates, reminders) • Use a scalable service such as Firebase Cloud Messaging or OneSignal • Include simple in-dashboard scheduling so my team can send campaigns without code In-app chat support • Real-time conversations, image/file sharing, and automated “typing” indicators • Prefer plug-and-play SDKs like Twilio, Intercom, or Sendbird, but I’m open to other proven stacks • Chat history must sync across devices Loyalty program • Points accrual for purchases, referrals, and special events • Rewards catalogue with point redemption flow • Admin interface for adjusting rules, tiers, and promotions Acceptance criteria 1. Zero critical crashes added to the existing build (confirmed via TestFlight / Google Play internal testing) 2. All three features pass QA on the latest two OS versions for iOS and Android 3. Clear, commented code plus setup documentation so my in-house team can maintain it If this sounds like a fun challenge, tell me which framework you’d use and one similar feature you’ve shipped before. Let’s make our users stick around longer—and enjoy every second of it.
