Senior Next.js Developer Needed to Take Over Existing AI Language Learning MVP

Senior Next.js Developer Needed to Take Over Existing AI Language Learning MVP I am looking for a senior full-stack developer to take over and improve an existing AI-powered language learning MVP. The platform is already built and includes: Next.js frontend PostgreSQL database OpenAI integration (speech transcription and AI feedback) Placement test Lesson system Teacher dashboard Referral/affiliate system Email integrations Admin/content management functionality My immediate goal is not to build new features. The priority is to audit the existing codebase, stabilize the platform, resolve outstanding issues, and prepare the MVP for real-world validation. Deliverables: Full code audit Architecture review Stabilization plan Critical bug fixes UX and workflow review Review of AI feedback implementation Review of content management capabilities Recommendations for a long-term content management and site management architecture A key objective is reducing founder dependence on developers. In the next phase, I would like to be able to manage lessons, placement activities, images, audio, prompts, onboarding content, and general site content without requiring development work for routine updates. Important: Experience taking over existing codebases is required. Experience with Next.js, PostgreSQL, OpenAI APIs, and SaaS products is required. Strong communication skills are important. Product thinking and UX awareness are highly valued. Please include examples of projects where you inherited an existing application and improved or stabilized it. This could lead to an ongoing relationship if the collaboration is successful.
