I’m preparing to launch a cross-platform matrimonial application and need a specialist who can take the idea from concept to production-ready detail. The stack is set—React Native for the mobile client, NestJS for the backend API layer, and MySQL as the persistent data store—but everything else still needs to be mapped out clearly before coding begins. What I need from you is a complete, actionable blueprint that any dev team could pick up and start building immediately. This includes defining all core modules, crafting a scalable database schema, outlining secure authentication flows, and specifying each REST/GraphQL endpoint in NestJS. Because the product will run on React Native, I also expect screen-by-screen wireframes paired with user stories so the mobile experience and backend contract stay perfectly aligned. Deliverables • Functional specification: user journeys, acceptance criteria, error states • Low- to mid-fidelity wireframes for every major screen in React Native • Database design: ER diagram, indexing strategy, migration plan for MySQL • API reference: endpoint list with methods, request/response samples, auth guards in NestJS terminology • Non-functional requirements: performance targets, security considerations (OWASP), deployment environment notes • High-level project plan with milestones and estimated effort Your output should be provided in a well-structured document set (Markdown, Figma links, or similar) plus any diagrams in an open format (e.g., draw.io XML or SVG) so future edits are simple. If you have proven experience drafting technical specifications for social or matchmaking apps—especially on this stack—let’s get started right away.
