A comprehensive full-stack web application that aggregates and analyzes multi-source lead data with real-time Google Analytics integration, advanced filtering, and subscription billing management.
Project scope
Greenfield project architected and developed as a complete full-stack solution, spanning from database design through API development to user-facing admin dashboards. The application processes high-volume lead data with real-time analytics integrations and multi-account support.
Responsibilities
- Built complete Google Analytics API integration with advanced request builder for dynamic segmentation and custom metrics reporting
- Designed and implemented RESTful APIs with Doctrine ORM for complex data relationships and multi-tenant architecture
- Developed admin dashboard interface leveraging Sonata Admin Bundle with role-based access control and custom filtering capabilities
- Created data export functionality supporting multiple formats (PDF, CSV) with WkHtmlToPdf integration
- Integrated Chargebee subscription billing system with recurring payment processing
- Built dynamic menu system with form-driven configurations for customizable user experiences
- Implemented command-line utilities for batch data processing and system maintenance
- Optimized database queries and implemented caching strategies for high-performance reporting
Outcomes & results
The platform successfully launched as a multi-tenant SaaS solution handling 100+ concurrent user accounts processing real-time lead intelligence from multiple data sources. Integration with Google Analytics API and Chargebee billing system enabled automated revenue operations and eliminated 95% of manual data collection processes.
