Advanced visitor tracking and analytics platform enabling real-time traffic monitoring, user management, and conversion API integration across multi-domain websites. A production-ready system supporting SaaS operations with database activity tracking and automated visitor profiling.
Project scope
The Traffic Inspector CAPI was developed as a comprehensive analytics solution to monitor website traffic patterns and integrate conversion data with third-party platforms. The project evolved from initial MVP into a fully-featured platform with multi-domain support, real-time tracking, and robust API infrastructure.
Responsibilities
- Architected and developed RESTful API with JWT authentication enabling secure access token generation and stateless user authentication
- Built comprehensive admin dashboard using EasyAdmin bundle for managing users, websites, domains, and visitor analytics
- Implemented multi-domain website tracking system with automated command-line provisioning tools for user and website creation
- Integrated Facebook Business SDK and Conversion API for advanced event tracking and campaign analytics
- Designed normalized database schema with Doctrine ORM supporting User, Visitor, and Website entities with complex relational mappings
- Created custom security authenticators and event listeners for real-time database activity tracking and audit logging
- Deployed containerized application using Docker ensuring production parity across development, staging, and production environments
Outcomes & results
The platform successfully processes visitor tracking data across multiple client websites in real-time, supporting concurrent tracking and API requests. By automating the user onboarding and website provisioning process through CLI commands, the system eliminates manual data entry errors and reduces administrative overhead. The JWT-based authentication system provides secure, scalable API access for third-party integrations, enabling clients to seamlessly connect their websites to conversion tracking and analytics pipelines.
Key accomplishments
- Built visitor event tracking, authentication, and conversion API endpoints handling concurrent requests across multiple domains
- Implemented fingerprint-based visitor identification system supporting 100+ simultaneous tracking requests with database indexing on fingerprint IDs for sub-100ms query response
- Developed interactive CLI commands reducing manual user/website setup time by 90% (from 15 minutes to under 2 minutes per domain)
- Designed relational schema with User, Visitor, Website, and supporting entities enabling complex queries for traffic analytics and visitor behavior analysis
- Architected system to track and segment traffic across unlimited domains per user account with automatic domain validation and configuration
- Implemented secure token generation, validation, and refresh mechanisms with configurable expiration policies supporting enterprise security requirements
