I have a cross-platform mobile app for both iOS and Android that is nearly feature-complete. What I need now is an experienced developer who can step in, make sure the MongoDB (NoSQL) database is well structured and performant, set up a reliable hosting environment, and shepherd the builds all the way through App Store and Google Play submission. The work involves reviewing the existing data models, suggesting and applying improvements, configuring the production database and server, and then guiding me through code signing, provisioning profiles, store compliance checks, and the final launch. Clear explanations and steady follow-up are important to me, because I want to understand each decision and keep things maintainable after release. Deliverables I would like to see: • O...

...must be preserved so future updates keep everything aligned. • Order side When a customer places an order, the bridge catches it instantly, calls the supplier API to purchase the corresponding digital key, retrieves the key and posts it straight back through the store API so the customer receives it without delay. Technical notes – Both APIs are REST. – A small, fast database (SQL or NoSQL is fine) should sit in the middle for caching, mapping and deduplication. – On any failed call the bridge should automatically retry with exponential back-off; I’ll review other alerting/logging options later, but solid retry logic is essential from day one. – Idempotency is critical so duplicate orders never slip through. – Clean code, c...
