Full-Stack Developer for AI SaaS

We are looking for an experienced full-stack developer with strong Lovable experience to help finalize Helm AI, an AI-powered General Manager designed to help businesses manage their daily operations. The majority of the product has already been developed using Lovable. We are not looking to rebuild it from scratch. We need someone who can take ownership of the existing applications, identify incomplete functionality, resolve bugs, ensure both platforms work together seamlessly, and prepare the product for launch. Applications 1. Helm AI Web App The main management platform for business owners and managers. It includes dashboards, AI management capabilities, financial reporting, sales analytics, inventory, staffing, scheduling, tasks, and other business management tools. 2. Helm Connect The complementary application for business operations and staff. It must work seamlessly with the main Helm web application, using synchronized business information, accounts, permissions, and operational data. Access to both Lovable projects and relevant technical documentation will be provided after hiring. Responsibilities 1. Complete integration between both applications Ensure both applications use a properly synchronized backend and database. Ensure updates made in one application correctly appear in the other. Fix authentication, user roles, permissions, and account synchronization. Resolve any integration errors, broken API calls, or inconsistent data. Ensure businesses, employees, tasks, and operational information remain synchronized. 2. Fix bugs and complete existing features Audit every page, button, form, workflow, and navigation element. Identify unfinished, broken, or placeholder functionality. Complete existing features according to the approved specifications. Resolve frontend and backend bugs. Fix loading issues, broken redirects, and application errors. Ensure the applications work properly across desktop and mobile screen sizes. 3. Verify core Helm functionality Review and test existing functionality across: AI General Manager and AI chat Business dashboards and analytics Sales and financial reporting Inventory management Employee management and scheduling Tasks, alerts, and notifications Business onboarding and waitlist/approval workflows Multi-business and multi-location management Industry-specific experiences, including restaurants and car rentals Third-party integrations already implemented or configured Any missing integrations, credentials, or features requiring substantial new development must be documented during the initial audit. 4. Improve the overall experience Ensure smooth navigation and responsive design. Remove unnecessary friction from onboarding. Verify that users see the correct functionality for their roles and business type. Improve error handling and application performance. Make both applications consistent and professional. 5. Perform complete quality assurance Test important user journeys from beginning to end. Verify data synchronization and persistence. Test account creation, authentication, permissions, and business onboarding. Check for database errors, security issues, and failed integrations. Resolve all identified critical and high-severity defects within the agreed scope. Document remaining lower-priority issues and any external blockers. Required Experience Strong hands-on experience with Lovable. React, TypeScript, and modern full-stack development. Supabase/PostgreSQL or equivalent backend experience. API integrations and authentication. Debugging existing SaaS applications. Database synchronization and access controls. End-to-end testing and production deployment. Expected Deliverables Initial technical audit with a prioritized issue list. Properly synchronized Helm Connect and Helm web applications. Completed and repaired functionality within the agreed scope. Tested critical workflows across both platforms. Working deployment and documented changes. A final testing report, outstanding-issues register, and technical handover. We expect clear communication and regular progress updates. The project will be accepted after successful testing of agreed functionality, not simply after code changes are made. Budget $1,000 fixed price, divided into milestones. Please apply only if you have experience working with existing Lovable applications and can clearly explain how you would approach the audit, integration, debugging, and final testing. Include examples of Lovable projects you have completed, your experience connecting multiple applications to a shared backend, and your estimated completion timeline. We are looking for someone reliable who can help us take Helm AI from its current state to a stable, functional, launch-ready product.
