PROJECTEU-Compliant B2B AI Chatbot Platform with Custom Document Training
RATIONALEAzure OpenAI (EU region) or AWS Frankfurt ensures data residency requirements critical for GDPR and financial sector compliance in the EU. PostgreSQL with pgvector eliminates the need for a separate vector database, reducing infrastructure complexity while maintaining GDPR-compliant data handling. Auth0 provides enterprise-grade SSO which is a non-negotiable for B2B finance clients who require SAML integration with their existing identity providers.
TECH STACK
FrontendNext.js 14 (App Router) with TypeScript and Tailwind CSS
BackendNode.js with Express or Fastify, Python microservice for AI/ML pipeline
DatabasePostgreSQL (primary, GDPR-compliant hosting) + pgvector for document embeddings
AuthAuth0 with enterprise SSO (SAML/OIDC) support and role-based access control
HostingAWS EU-WEST-1 (Frankfurt or Ireland) for data residency compliance, Docker + ECS
ExtrasOpenAI GPT-4 or Azure OpenAI (EU region) for LLM inference, LangChain for RAG pipeline orchestration, Stripe for subscription billing, Socket.io for real-time chat streaming, AWS S3 (EU region) for document storage with server-side encryption, Redis for session management and rate limiting, Sentry for error monitoring, Terraform for infrastructure as code

⚠ RISK FLAGS
!GDPR and EU AI Act compliance for finance sectors is non-trivial — you will need a qualified Data Protection Officer (DPO) review before going live; budget separately for legal/compliance counsel (~$3,000–$8,000 USD)
!Finance sector clients (banking, insurance) often require ISO 27001 or SOC 2 Type II certifications before vendor approval — this is a sales blocker that cannot be solved with code alone and may delay enterprise deals by months
!Using third-party LLMs (OpenAI/Azure) means client data leaves your infrastructure even briefly — some EU finance clients will mandate on-premise or private VPC deployments, significantly increasing infrastructure complexity and cost
!RAG accuracy on domain-specific financial/legal documents can be poor without prompt engineering and evaluation pipelines — budget for 2–3 weeks of RAG quality tuning post-launch or risk client churn
!Seed budget may be insufficient if the security audit uncovers architectural issues — compliance-grade penetration testing and remediation alone can cost $5,000–$15,000 USD
!'ASAP' timeline conflicts with the compliance rigor required for EU finance clients — rushing GDPR audit logging, data residency validation, or access controls creates legal liability for your B2B clients and will be a hard blocker for sales
