Overview
A comprehensive system to manage and streamline building inspections for construction projects. This system provides functionalities for scheduling inspections, recording inspection data, generating compliance reports, and managing inspection results.
Technologies Used:
Flask for building RESTful services
SQLAlchemy for database ORM
PostgreSQL for managing relational data
Redis for caching and background job management
Docker for containerization
Nginx for load balancing and serving as a reverse proxy
Key Features:
Inspection Scheduling Service: Allows users to schedule inspections and assign inspectors to specific building sites and projects.
Inspector Management Service: Manages inspector profiles, roles, and availability.
Compliance Report Service: Generates compliance reports based on inspection results and regulatory requirements.
Notification Service: Sends automated email or SMS notifications for scheduled inspections, results, and compliance reminders.
Document Storage Service: Stores and retrieves inspection reports, compliance documents, and related photos.
Highlights:
Developed RESTful APIs using Flask to handle inspection scheduling, report generation, and notifications.
Utilized JWT-based authentication to secure access and manage roles (inspector, admin, contractor).
Implemented document storage using Amazon S3-compatible storage for scalability and security.
Deployed microservices as Docker containers to ensure consistent environments across development, staging, and production.
Used Redis for session management and to cache frequently accessed inspection data.
