Project description:
"Freelance Full-Stack Developer Needed to Debug & Fix Chat Application (Short-Term)

About the Project
We have a chat-based web application that integrates AI/LLM responses, multimedia input (voice, image), and progressive user interactions. The application is already built, but several technical and functional issues are preventing smooth operation. We need an experienced developer who can quickly troubleshoot, debug, and deliver a stable working version.

What You’ll Work On
• Debugging session management and ensuring conversation context is preserved across turns.
• Fixing chat state machine logic (confirmable checkpoints, quick replies, remediation loops).
• Ensuring voice input (STT) with Azure Speech Service (EN/HI/Hinglish) works seamlessly, with browser-native fallback.
• Testing vision/photo-to-text flow (image upload + ROI crop + OCR parse).
• Fixing recap/summary sharing and profile prompts.
• Ensuring frontend complies with brand guidelines (colors, typography, responsive design, accessibility).
• Validating against API contracts (OpenAPI v4, Zod schemas) using the provided Client SDK and Postman collection.
• Documenting fixes and stabilizing the end-to-end app.

Tech Stack
• Frontend: React ([login to view URL]), TypeScript, TailwindCSS, shadcn/ui, Lucide icons, Lottie animations.
• Backend: Node.js/TypeScript, Express (or equivalent), REST APIs (/api/v4/turn, /status, /capabilities, /vision/*).
• Realtime: Server-Sent Events (SSE) / WebSockets for streaming responses.
• APIs/Integrations:
• OpenAI / LLM APIs (for tutoring/explanation responses).
• Azure Speech Service (STT/TTS).
• Image upload & OCR parsing.
• Database: Postgres (with analytics + event tracking schemas).
• Dev/Hosting: Replit (cloud IDE), GitHub repo for source control.
• Testing: Postman collection, Zod schema validation, automated contract tests.

Requirements
• Strong full-stack experience (React/[login to view URL] + Node/TypeScript).
• Solid debugging skills with SSE/WebSocket flows, API integration, and state management.
• Experience working with Azure Speech or other STT/TTS services.
• Knowledge of Zod/OpenAPI contracts and schema validation.
• Familiarity with Replit or similar cloud IDEs.
• Strong eye for UI/UX polish and accessibility compliance.

Nice to Have
• Prior work with chat-based or AI-driven applications.
• Multi-lingual input handling (English/Hindi/Hinglish).
