Project Overview We are looking for an experienced development team (or senior full-stack developer) to build a document and quality management platform for large-scale construction projects (energy, infrastructure, industrial projects). This is not a simple CRUD application. The core complexity lies in managing interconnected documents, strict version control, field data collection, and automation powered by AI, all within a user experience designed for construction professionals. The platform will be delivered as a turnkey solution, not a SaaS subscription, and must be production-ready. Core Concept In construction projects, quality and compliance are managed through multiple document types (plans, inspections, checklists, technical queries, approvals). These documents are not isolated — they are part of a workflow and must be linked, versioned, and traceable. The platform must: - Treat documents as structured entities with states and relationships - Maintain full traceability between documents - Ensure users always work on the correct version - Reflect real construction workflows, not generic task management Key Functional Requirements 1. Interconnected Document System (Core Complexity) Each document type (e.g. Inspection Plans, Work Packs, Inspections, RFIs, NCRs) must: - Be linked to other related documents - Update relationships automatically when new revisions are created - Preserve full version history (revisions, approvals, superseded versions) - Ensure downstream documents reference the correct active version Example: If an Inspection Plan is revised, all related inspections and work packages must clearly reference the new approved version while preserving historical data. 2. Document Versioning & Revision Control - Multiple revisions per document - Clear status flow (Draft, Submitted, Approved, Superseded, Closed) - Automatic propagation of version changes where applicable - Full audit trail (who changed what, when, and why) 3. AI Capabilities (Mandatory) The platform must include AI-powered features: OCR & Template Generation - Upload existing PDFs or spreadsheets - Automatically convert them into structured digital templates - Reusable across projects during onboarding Assisted Data Completion - AI suggestions to complete repetitive or structured fields - Reduce manual input for inspectors and QA teams Conversational AI (Chatbot) - Query project data using natural language - Retrieve document status, inspections, issues, and metrics - Generate automatic reports (quality reports, summaries, progress updates) 4. Field Application (Mobile) - A mobile application (iOS & Android) is required to: - Perform inspections on site - Complete checklists and forms - Attach photos and evidences - Work offline when there is no connectivity - Automatically sync data when connection is restored Offline-first behavior and reliable synchronization are critical. 5. Drawings & Markups The platform must include a Drawings module where users can: - View PDFs directly in the browser - Create markups and annotations (similar to Procore) - Link markups to inspections, RFIs, or NCRs - Maintain version control for drawings 6. Dashboard & Analytics - High-level dashboard showing project quality status - Metrics by document type, discipline, and status - Visual indicators (cards, donut charts, progress bars) - Near real-time updates via WebSockets or similar 7. UX & Design Approach The target users are inspectors, supervisors, and field engineers. The UI must be: - Simple and intuitive - Low cognitive load - Optimized for fast actions in field conditions We are open to: - Design being handled as a separate phase - Delivering UI/UX as a standalone design system (Figma) before development - Using the design as a strict functional requirement for implementation Technical Stack (Preferred) - Frontend (Web): React (TypeScript), PWA architecture - Mobile: React Native or PWA wrapped as native app - Backend: Node.js (NestJS preferred) - Database: PostgreSQL (complex relations + JSON support) - Storage: Object storage (e.g. S3) - Auth: JWT, role-based access control - Realtime: WebSockets - Deployment: Docker, Kubernetes - AI Integration: OCR services + LLM APIs - Offline Sync: Local storage + background synchronization Non-Functional Requirements - Strong security (TLS, encrypted storage, audit logs) - Scalable architecture (multi-project, multi-client) - Clean, well-documented codebase - Clear separation of concerns and domain-driven structure - Performance optimized for dashboards and field usage Engagement Model We are looking for: - Senior developers or a small experienced team - Proven experience with complex business logic and data relationships - Experience with offline-first apps and synchronization - Experience integrating AI into real production systems

Hello, I understand this is not a simple app. What you are building mirrors how real construction projects actually work, with documents that depend on each other, strict version control, and people in the field who cannot afford confusion or downtime. I will approach this as a quality management system first, not just a tech platform. I will design and build the core document engine so revisions, links, and traceability behave correctly at all times, while keeping the interface simple enough for inspectors and supervisors to use on site. I will also integrate AI in a practical way, helping with template creation, data completion, and natural language queries that actually save time, not add complexity. On the technical side, I am comfortable with the stack you outlined and with offline-first mobile workflows, syncing, and real-time updates. My goal is a production-ready system that reflects real construction workflows, scales cleanly, and can be handed over as a turnkey solution with confidence. Looking forward to discussing further. Best regards, Kamran

I understand this flow deeply because I’ve already built systems with interconnected documents, strict versioning, offline field workflows, and traceability — this isn’t theoretical for me. What you’re describing reflects real construction QA/QC operations, not generic software, and that’s exactly where my experience fits. This platform’s complexity lives in document relationships, revision propagation, auditability, and offline reliability, not CRUD screens. I approach this as a domain-driven system, where documents are stateful entities with lifecycle rules and enforced correctness. How I’d approach this platform • Design a document-centric domain model where inspections, RFIs, NCRs, drawings, and work packs are fully traceable and version-aware • Implement robust revision control with automatic downstream reference updates and full audit history • Build offline-first mobile workflows for inspections, photos, and checklists with reliable background sync • Integrate AI capabilities: OCR-to-template conversion, assisted data entry, and conversational querying of project data • Drawings module with PDF viewing, markups, linking, and version control • Real-time dashboards using WebSockets for near-live project status • Security-first architecture with RBAC, encrypted storage, and audit logs Happy to discuss further over chat or a call, whichever you prefer. Best regards, Jenifer

Hello There!!! ⚜️⭐⭐⭐⭐⚜️(( Interconnected document control with AI driven quality workflows ))⚜️⭐⭐⭐⭐⚜️ This project stands out because it treats construction documents as living, connected entities rather than static files. You are clearly aiming to mirror real world quality and compliance workflows where versioning, traceability, and field execution must stay perfectly aligned across large projects. I have worked on complex platforms with heavy business logic, strict audit trails, and offline first mobile usage for field teams. I am experienced with Node based backends, relational data modeling in PostgreSQL, and building React and React Native interfaces that stay usable in demanding site conditions. I have also integrated OCR and language models into production systems for document structuring and reporting. My approach would be to design a strong domain model around documents, revisions, and relationships first, then layer AI services for template generation, assisted input, and conversational queries. This keeps the system reliable while allowing automation to add real operational value. Three most important features: Full document versioning with automatic relationship propagation Offline capable mobile inspections with reliable synchronization AI powered OCR, assisted data entry, and natural language reporting I would welcome a deeper discussion to review your workflows and align on a phased, production ready delivery plan. Warm Regards, Farhin B.

Dear Hiring Team, We are very interested in building your document and quality management platform for large-scale construction projects. This is clearly a domain-driven system where the real challenge lies in managing interconnected documents, strict version control, traceability, and offline-first field execution—not just CRUD operations. Our experience aligns closely with these requirements. We understand that documents such as Inspection Plans, Work Packs, Inspections, RFIs, and NCRs must function as structured entities with lifecycle states, bidirectional relationships, and automatic propagation of revisions, while preserving full audit history. Ensuring that downstream documents always reference the correct approved version—without breaking historical records—is a core architectural concern we are comfortable solving. A few clarification questions: Will document workflows and status transitions be configurable per project or fixed globally? Do drawings require layered markups with role-based visibility and approval? How should offline conflict resolution be handled when multiple inspectors update related documents? Are AI models expected to be client-isolated or shared with data boundaries? We would be happy to discuss architecture, milestones, and a phased delivery approach. Best regards, Inciterz Tech
