 ## 🏛️ Architectural Decisions & Rationale
 
 ### Service Technology Choices
-- **Dashboard Service**: Next.js + tRPC (existing, proven stack)
-- **Data Ingestion Service**: Golang (high-performance CSV processing, concurrency)
-- **AI Processing Service**: Node.js/Python (existing AI integrations, async processing)
-- **Message Queue**: Redis + BullMQ (Node.js ecosystem compatibility)
-- **Database**: PostgreSQL (existing, excellent for multi-tenancy)

+-   **Message Queue**: Redis + BullMQ (Node.js ecosystem compatibility)
+-   **Database**: PostgreSQL (existing, excellent for multi-tenancy)
 
 ### Why Golang for Data Ingestion?
-- **Performance**: 10-100x faster CSV processing than Node.js
-- **Concurrency**: Native goroutines for parallel transcript fetching
-- **Memory Efficiency**: Lower memory footprint for large CSV files
-- **Deployment**: Single binary deployment, excellent for containers
-- **Team Growth**: Easy to hire Golang developers for data processing

 ### Migration Strategy
-1. **Keep existing working system** while building new services
-2. **Feature flagging** to gradually migrate companies to new processing
-3. **Dual-write approach** during transition period
-4. **Zero-downtime migration** with careful rollback plans

 ### Compliance Benefits
-- **Data Isolation**: Each service has limited database access
-- **Audit Trail**: All inter-service communication logged
-- **Data Retention**: Automated per-company data lifecycle
-- **Security Boundaries**: DMZ for ingestion, private network for processing

 ## Notes
-- **CRITICAL**: Architectural refactoring must be priority #1 for scalability
-- **Platform Management**: Notso AI needs self-service customer onboarding
-- **Compliance First**: GDPR/ISO 27001 requirements drive service boundaries
-- **Performance**: Current monolith blocks on CSV/AI processing
-- **Technology Evolution**: Golang for data processing, tRPC for type safety
