My mobile application for the general public is already coded for both iOS and Android, but it still needs a final push before launch. I’m looking for someone who can take full ownership of the finishing phase: hunt down and fix every bug, wire up eight payment gateways alongside two payout methods, connect the existing P2P + SFU server, move the backend to its new hosting environment, document the whole process, and finally publish stable builds to the App Store and Google Play. Deliverables • End-to-end functional and regression testing with issue resolution • Seamless integration of 8 payment gateways and 2 payout flows already selected in the codebase • Configuration of P2P and SFU services inside the app so real-time features perform smoothly under load • Migration of the complete stack to the new hosting account and verification that all services stay online • Clear step-by-step documentation covering build, deployment, and server setup • Release-ready iOS and Android builds, successfully submitted and approved in both stores Acceptance Full payment is released once every item above is delivered, builds are live in both stores, and the documentation lets another developer replicate the deployment without guesswork. No advance milestones—if that schedule works for you, let’s get started.
