**Full-Stack Developer Needed — AI-Powered Contract Review Web Application** We are building a web-based contract review and risk management platform for the construction and real estate sector. The platform uses an LLM API (Anthropic Claude) to analyse contracts and generate structured risk assessments, Excel workbooks, and PDF executive summaries. We have already built the review logic and system prompt. We need a developer to build the application around it. **What you will build:** - Contract upload workflow (PDF/DOCX) → LLM review engine → structured output - Programmatic Excel report generation (multi-sheet workbooks with RAG colour coding) - Programmatic PDF generation (branded executive summary documents) - User dashboard with activity feed, portfolio usage statistics, and quick action buttons - Searchable contract library with filter/sort by risk level, contract type, date, and project - Five-section portal: Dashboard, Contracts, Reviews, Reports, Settings - Multi-user accounts with role-based access (Admin / Standard User) **Skills required:** - Full-stack web development (React or similar frontend; Python/Node.js backend) - LLM API integration (prompt assembly, response parsing, error handling) - PDF/DOCX text extraction including OCR for scanned documents - Programmatic Excel and PDF generation (openpyxl / ExcelJS / ReportLab / PDFKit) - Cloud hosting and deployment (AWS, GCP, or Azure); Docker - Authentication, session management, and role-based access control **We will provide:** Complete system prompt, full output formatting specifications, branding assets, sample contracts, and test API key. We are available throughout the build for questions and review. **To apply, please include:** 1. Relevant experience — especially AI-integrated apps and document/report generation 2. Proposed tech stack 3. Examples of previous work (links preferred) 4. Indicative timeline and cost range This is a production-ready build, not a prototype. Please only apply if you have delivered comparable projects.

Hello! I understand you’ve already built the review logic and Claude system prompt. You now need a production-grade application layer that handles ingestion, orchestration, reporting, and secure multi-user access around that engine. Here’s how I’d approach it: • React + TypeScript frontend with structured 5-section portal • Python FastAPI backend for clean LLM orchestration and async processing • PDF/DOCX ingestion with OCR fallback for scanned contracts • Robust prompt assembly, structured response parsing, and failure handling • Multi-sheet Excel generation using openpyxl with RAG colour logic • Branded executive PDF summaries via ReportLab • PostgreSQL for contract metadata, risk scores, and audit logs • Role-based access control with JWT + refresh token strategy • Dockerized deployment on AWS with S3 storage and background workers Core architecture: Upload → Extraction → LLM analysis → Structured JSON validation → Report generation → Persisted artifacts → Dashboard analytics. Deliverables include: • Full contract upload-to-report workflow • Searchable contract library with advanced filters • Usage statistics dashboard and activity feed • Admin/Standard role separation • CI/CD pipeline and production-ready deployment Let’s open the chat to align on scale, expected concurrency, and reporting complexity. Best regards, Jasmin

Hello, I’m Muhammad Awais. I will build a full-stack AI contract review app around your existing review logic and prompts, tailored for construction and real estate work. My approach: set up a robust multi-user web app with React frontend and Python/Node backend, integrate the Claude API for contract analysis, and return structured risk outputs, Excel workbooks, and branded PDFs. I’ll implement secure RBAC, a five-section portal (Dashboard, Contracts, Reviews, Reports, Settings), and a searchable library with advanced filters. For documents, I’ll add OCR for scanned PDFs, reliable PDF/DOCX parsing, and fail-safe error handling for API calls. Reports will auto-generate multi-sheet Excel files with color-coded risk sections and branded PDF executive summaries. The stack will be cloud-friendly (Docker, AWS/GCP/Azure), with CI/CD, authentication, and scalable storage. What is the single most critical KPI you want to track in the dashboard to drive adoption and ROI? Best regards,

Hello, I am a full-stack developer with extensive experience building AI-integrated web applications for document analysis and report generation. For your contract review platform, I recommend a React frontend paired with a Python backend (FastAPI or Django) to handle LLM API integration, OCR-based PDF/DOCX parsing, and programmatic Excel/PDF generation using libraries like OpenPyXL and ReportLab. The system will include role-based authentication, a multi-section dashboard, searchable contract library, and structured output workflows, fully containerized with Docker for cloud deployment on AWS or GCP. I can deliver a production-ready platform with clean code, deployment instructions, and integrated LLM-based review capabilities within 6–8 weeks, and I can share examples of prior AI-driven document processing and reporting applications.

✅AI Contract Review App Hello I have read your project requirements, i can help you develop the AI contract review app you need. With over a decade of experience in Full Stack Development, I have delivered numerous projects with AI integration including your specific requirements of document processing and report generation. To bring your vision to life, I propose utilizing React as the frontend framework, coupled with Python for backend development for seamless integration with LLM API in addition to Node.js for any relevant functionalities. Recently I have been working on Lovable AI for developing a gaming platform using it, complete with chat-based agent logic, expressive front-ends, and backend integrations. In other project, implemented a fully automated AI agent system for intelligent meeting creation using ElevenLabs Conversational AI and Gemini (via a custom agent brain). The flow integrates voice interaction, natural language processing, location precision, and frontend. Whether you're building an internal assistant, a public-facing voice agent, or an integrated AI productivity tool, I can help bring your vision to life with robust, scalable architecture and a human-like user experience. I would love to connect and explore how we can contribute to your AI initiative. Regards Sunaina

This looks like a great fit, I will build your contract review platform React frontend, FastAPI backend, contract upload with OCR, Claude API integration using your prompt logic, Excel workbooks with RAG color coding (openpyxl), branded PDF summaries (ReportLab), five-section portal with searchable contract library, and RBAC. Deployed via Docker on AWS. I will run contract reviews through a Celery task queue so Claude calls process async large documents take time and blocking the UI kills the experience. The dashboard will show review status and notify on completion. Questions: 1) What is the typical contract length will any need chunking before sending to Claude? 2) Should OCR handle handwritten annotations, or only printed/scanned text? 3) Do you need audit logging on who reviewed which contract and when? I'll share relevant links with estimate timeline and cost in chat. I'd prefer to review your system prompt and output formatting specifications first so I can provide a considered and accurate estimate rather than a rough figure. Looking forward to discussing further. Best regards, Kamran

Hi, this is Elias from Miami. I understand the build: you already have the Claude review logic + system prompt, and you need the full production web app around it—contract upload (PDF/DOCX, incl. OCR) → LLM review → structured outputs, plus programmatic Excel multi-sheet workbooks with RAG color coding and branded PDF executive summaries. Users get a 5-section portal (Dashboard/Contracts/Reviews/Reports/Settings) with an activity feed, portfolio usage stats, quick actions, a searchable contract library (risk/type/date/project), and multi-user RBAC (Admin/Standard). Deployed in cloud with Docker, secure auth/sessions, and robust error handling on the LLM pipeline. Q1: Do you need strict determinism/versioning per review (store prompt+model version+inputs so results are auditable and repeatable)? Q2: For OCR, do you prefer a managed service (AWS Textract/GCP Vision) or fully self-hosted (Tesseract) to control cost/data residency? Q3: Should the Excel/PDF outputs be generated synchronously or via a job queue (recommended) for large contracts and high concurrency? If you share your output spec + sample contracts, I can propose the stack and a milestone timeline/cost range.
