Lovable Developer Needed to Finalize, Test & Launch Existing Multi-User App

I’m looking for an experienced developer, preferably with Lovable experience, to help finalize, thoroughly test, and launch an existing application that has already been substantially built using Lovable. The platform is being launched in phases and currently includes: Student Portal – Paid Supervisor Portal – Paid Trainee Portal – Free when invited/connected by a paid Supervisor I am currently preparing to launch the Student and Supervisor portals, along with the Trainee functionality required for Supervisors to manage and work with their trainees. Current Project Scope This is not a ground-up app development project. The application already exists in Lovable and has been substantially built. I need someone who can work within the existing project, understand the current structure and workflows, identify technical issues, make necessary fixes, and get it production-ready. A major priority is ensuring the Supervisor ↔ Trainee system works reliably end-to-end. The Supervisor portal allows Supervisors to: Invite trainees and connect their accounts Manage multiple trainees Assign tasks and activities Track trainee progress and task completion Conduct and record assessments of trainee skills and competencies Complete, review, and manage supervision-related documentation Review trainee submissions and records Electronically sign documents and facilitate trainee signatures where required Communicate/interact with connected Trainee accounts Ensure each trainee’s assignments, assessments, documents, signatures, and other information remain associated with the correct account These workflows need to be tested from both the Supervisor and Trainee sides so that actions taken in one account are correctly saved and reflected in the other. Additional Pre-Launch Needs I need assistance with: Reviewing the existing Lovable project and its current architecture Testing and debugging existing functionality Testing the Student portal and paid Student accounts Testing paid Supervisor subscriptions Ensuring free Trainee accounts are correctly tied to paid Supervisor accounts Testing invitation and account-linking workflows Testing authentication, account creation, login, roles, and permissions Testing subscriptions/paywalls and feature access Ensuring assignments, assessments, documents, signatures, progress data, and other records save and display correctly Testing data synchronization between connected accounts Identifying and fixing bugs, edge cases, and broken workflows Reviewing the overall user experience across account types Preparing the application for production Handling the technical aspects of deployment and publishing Managing submission to the Apple App Store and Google Play Addressing technical requirements or issues that arise during the publishing/review process Future Development Additional phases are planned after this launch. A future phase will include a Parent Coach Portal, where paid Parent Coach accounts can invite and connect with Parent accounts. Parent accounts will be free when associated with a paying Parent Coach, similar to the Supervisor/Trainee structure. The Parent Coach portal is not part of the current scope, but I would ideally like to establish an ongoing relationship with a developer who can continue supporting and expanding the platform. Ideal Experience Experience with the following is strongly preferred: Lovable development and troubleshooting Working with and improving an existing Lovable project Taking an existing application from development to production Multi-user and role-based applications Linked accounts and invitation systems Assignments/task management Assessments and progress tracking Electronic documents and signatures Subscription/payment systems Database/backend integrations used with Lovable Apple App Store and Google Play publishing Production deployment, debugging, and ongoing maintenance When applying, please include: Your experience working specifically with Lovable Examples of Lovable apps or other applications you have taken to production Your experience with multi-user applications and linked accounts Your experience implementing/testing subscriptions and access permissions Your experience with electronic documents/signatures and user-generated records Apps you have successfully submitted to the Apple App Store and/or Google Play How you would approach auditing and testing an existing Lovable app before launch There is potential for continued development and ongoing maintenance after the initial launch if we work well together.
