Build a Reward App for Android (native) and iOS (native/browser), a marketing/managing webapplication and an integrated advertising platform.

The things/technologies you find in this description/list are mainly suggestions and we can talk about alternatives. Comments and feedback are welcome! It should be a reward App like CashChaCha, Tapporo, WHAFF, AppNana, appKarma, TinyLoot or CashMe with more features. I have developed a very simple prototype of the Android app with a backend. Different things - Experience with GIT source control - the app should be compatible with chinese android markets o users should be able to download the apk-file - Android: minSDKVersion is 2.3 (API 9) and maxSdkVersion 6 (API 23) - IDE for the Android-project: Android Studio - iOS: min 7 and max 9.1, Swift - API for developers - Login with different social media accounts - Users can save notifications - Google App Invites - a few other features Webapplication - should support IE8 - Users o Profile o Redeem points o a few other features - Admin o User management o Add rewards o Fraud management o Dashboard with KPIs o FAQ System o Support o Role-System o Marketing automation - a few other features Integrated advertising platform: App Installs (like Supersonic), Video App Installs (like Vungle), banners, interstitials - Self-serve/managed - check app installs: e.g. SDK/API - a few other features Design - Logo - images for store listing - Material design - Gamification: Awards/Badges - e.g. Google Play Games Services Technology - e.g. ReactJS (server-side rendering), nginx, Vert.x, Aerospike/Cassandra, Saltstack, RabbitMQ/ZeroMQ/Kafka/NATS, Ubuntu - monitoring tools (scalable approach) - based on microservices: e.g. Docker, Rancher, Kong Infrastructure - ovh cloud (openstack) o auto-healing/ -scale - Cloudflare: api for round-robin dns incl. healthcheck and for automatic firewall configuration - Google Cloud Messaging (GCM) - Amazon SES - should be optimized for security and performance o every part of the stack including JVM (avoid Garbage Collection) Security - [login to view URL] - OWASP Top 10 / OWASP Mobile Security Project - important actions should be validated on server - Private networks, separate systems, etc. - Fraud analysis o VPN/Proxy detection, device fingerprinting etc. o tracking and analysis of important events o you could use some parts of this architecture: • [login to view URL] Performance: every request should be done in under 100ms Code and system-setup documentation are necessary. With each milestone you get the following stake of the salary: 1) Android app with backend: 20% 2) iOS app: 10% 3) infrastructure: 20% 4) advertising platform: 10% After two weeks testing period you get the remaining 40%. If you can deliver only a part of the project, please specify your price and the part. I am located in Germany and am online from 9 am until 11 pm CEST.
