EdTech Developer for Live Deployment Preparation -- 2

We need an EdTech developer to prepare our platform for commercial live deployment. Must have Next.js, TypeScript, PostgreSQL, Stripe payments, LMS architecture, role-based dashboards, adaptive testing logic, certificate/report generation, downloadable resources, and secure cloud deployment. The developer must be able to review the existing codebase, fix missing routes or logic, connect all dashboards to real database records, build a full platform-owner admin dashboard, complete the paid CEFR placement-test flow, verify Stripe webhook integration, ensure curriculum and course content are fully connected, and deploy the platform on production environment like DigitalOcean. This is not a prototype task; the selected developer must be capable of delivering a secure, scalable, commercially operational ESL learning and assessment platform for learners, teachers, institutions and administrators.
