Full Stack App Audit

@Microlent

Hello This is exactly the kind of work I enjoy. Not building from scratch but going deep into an existing system, understanding how it was built, and making sure every piece holds up under real conditions across all three platforms. I am comfortable across both client-side and server logic and have audited production applications built on no-code and low-code foundations before. I know the common failure points: inconsistent API error handling, auth edge cases, data mismatches between mobile and web, and third-party integrations that work in isolation but break in sequence. Here is how I will approach this: - Week 1: Full codebase review against your documentation. I will map every documented flow to its implementation and flag anything that does not match before writing a single fix. - Week 2: End-to-end testing across iOS, Android, and Web. Every backend integration tested including APIs, database calls, authentication flows, and third-party services. Bugs logged with root cause and fix applied. - Delivery: A concise findings report covering every issue discovered, fixes applied, and any remaining recommendations for your next phase. I am happy to sign an NDA before receiving access. Ready to start as soon as documentation and staging credentials are shared. Best, Jenifer

Hi, As per my understanding: Full-stack audit of live Lovable app (iOS/Android/Web)—verify docs vs functionality, test APIs/DB/auth/integrations, fix bugs/perf issues, deliver report. Implementation approach: - End-to-end testing w/ docs/staging access across platforms. - Backend: API/DB scans (Postman/Jest); frontend: UI flows/emulator checks. - 1wk: Audit/fixes/report w/ recommendations. I'll share my portfolio on your first message. Queries: Lovable framework details? NDA ready to sign? Best Regards
