Problem

Organizations need a centralized system to manage documents, track approval workflows, control access by role, and integrate 3D model viewing for construction projects.

My Contributions

Built fullstack document management features including workflow approvals and file versioning
Designed Node.js backend services with Redis caching for performance optimization
Integrated dual storage architecture: AWS S3 (cloud) and MinIO (on-premise)
Developed React web and React Native mobile apps with 3D model viewers
Implemented CI/CD pipelines with Jenkins and Docker, monitored with Grafana

Key Features

Document versioning and status tracking
Multi-step approval workflows
Role-based access control (RBAC)
3D model viewers (IFC, Revit, AutoCAD)
Real-time collaboration

Technical Highlights

→ Redis caching reduced API response time for frequently accessed documents
→ Dual storage strategy supports both cloud and on-premise deployment
→ Docker containerization enables consistent deployment across environments
→ Grafana dashboards provide real-time system health monitoring

Challenges & Solutions

Large file uploads causing timeout on slow networks

✓ Implemented chunked upload with progress tracking and resumable transfers

Cache invalidation when documents are updated across multiple users

✓ Redis pub/sub pattern for real-time cache invalidation
