Full-Stack React/Django Developer Needed to Finish Existing Internal SaaS Platform

I have an existing internal real estate operations platform that is already largely built using React, TypeScript, Django, Django REST Framework, and PostgreSQL. I’m looking for an experienced full-stack developer to take the current application through its final stage of development and deliver a polished, stable release candidate ready for internal launch. The core architecture and major functionality are already in place, including authentication, role-based permissions, properties, acquisitions, construction management, finance, dispositions, tasks, documents, activity tracking, and dashboards. This is not a new build or redesign. The work will primarily involve reviewing the application end-to-end in a real browser, identifying and fixing remaining bugs or incomplete workflows, resolving frontend/backend integration issues, and completing a final UI/UX consistency pass across the platform. This includes forms, tables, navigation, drawers/modals, responsive behavior, loading/error states, and general usability. I need someone who can work independently inside an existing codebase, understand the current architecture before making changes, and focus on getting the product across the finish line rather than unnecessarily rebuilding working components. The final deliverable should be a stable, polished release candidate that has been tested across the major workflows and user roles and is ready for us to deploy internally. Deployment and production infrastructure will be handled separately. Strong React/TypeScript experience is important, along with Django/Django REST Framework experience and the ability to troubleshoot issues across both the frontend and backend. Experience finishing or stabilizing SaaS, CRM, ERP, dashboard, or other operational applications is strongly preferred. I’m looking to start immediately and would ideally like the final stabilization and handoff completed within approximately one week. Please include relevant examples of similar applications you have worked on, your availability, and your proposed price/timeline for completing the assignment.
