Vercel AI SDK Streaming, Vector Databases with pgvector & OWASP Security for LLMs
Get direct access to our production architecture templates and checklists.
Users expect instantaneous AI interactions. We utilize Next.js Edge Runtime and the Vercel AI SDK to stream OpenAI / Anthropic response tokens directly to React UI components with zero initial latency.
Rather than adding expensive specialized vector database vendors, we leverage the `pgvector` extension inside existing PostgreSQL instances for semantic similarity search and Retrieval-Augmented Generation (RAG).
Implementing strict prompt injection sanitizers, user-isolated vector namespaces, and rate-limiting guardrails to protect proprietary company data and prevent runaway API bills.
End-to-end full-stack software architecture, code reviews, and fixed-scope delivery sprints.
