I’m building a sealed-bid auction platform focused on Android and I need the full solution—from the mobile app that bidders use to a secure, browser-based admin panel that lets me run everything behind the scenes. On the Android side, users should be able to register, browse active lots, place a single hidden bid before the deadline, then receive an automatic notification once the winner is determined. All bids must stay confidential until the auction closes, so please give special attention to server-side logic and encryption. The admin panel is just as important. I need intuitive user management to approve or suspend accounts, real-time bid tracking to watch each auction’s progress, and clear reporting & analytics so I can export results, spot trends, and verify that the sealed-bid rules were followed. Deliverables • Full Android source code and compiled APK • Web-based admin panel with user management, bid tracking, and analytics dashboards • RESTful or GraphQL API connecting app and server • Basic documentation: setup, deployment, and a quick user guide Acceptance criteria • No bid values are exposed until an auction ends • Admin can view, filter, and export all bids and user activity • All data persists correctly if the server restarts • App passes Play Store review requirements If you’ve built auction or fintech apps before and can demonstrate airtight security and crisp UI/UX, let’s talk timelines and milestones.
