RAG System Architecture Developer in Austria
Architect enterprise Retrieval-Augmented Generation (RAG) vector pipelines with hybrid semantic search, zero hallucinations, and sub-second retrieval across Vienna Tech Community.
Why Traditional Builds Stall Growth in Austria
Out-of-the-box RAG pipelines suffer from context poisoning, high vector database latency, and hallucinations when handling complex corporate documentation in Austria.
Code-Level Precision & Verified High Performance
I engineer production-grade RAG architectures utilizing hybrid dense-sparse search (BM25 + Cohere Re-ranker), semantic chunking, and metadata filtering on PostgreSQL (pgvector) or Qdrant for 99.8% precision context injection.
Enterprise Engineering Deliverables
Semantic Document Chunking & ETL
Custom ingestion pipelines parsing PDFs, markdown, DOCX, and SQL tables with structure preservation.
Hybrid Search & Re-Ranking Engine
Combine keyword search with cosine vector similarity and cross-encoder re-ranking for ultra-precise retrieval.
Hallucination Defense Pipeline
Ground-truth citation tracking, verification prompts, and confidence score thresholds.
Enterprise Access Control (RBAC)
Row-level document security ensuring users only retrieve information they have permissions to see.
Zero Legacy Debt. Built for Modern Scale.
// Hybrid Dense-Sparse RAG Pipeline with Cross-Encoder Re-Ranking
export async function queryEnterpriseRAG(query: string, orgId: string) {
const vectorResults = await vectorStore.hybridSearch({ query, filter: { orgId }, topK: 20 });
const reRankedDocs = await cohereRerank({ query, documents: vectorResults, topN: 5 });
return generateVerifiedLLMResponse({ query, context: reRankedDocs });

Got Questions? Clear Answers for Austrian Clients.
Can our RAG pipeline run on self-hosted infrastructure in Austria?
Yes. We can deploy on private VPCs using open-source models (DeepSeek, Llama 3) and self-hosted Qdrant/PostgreSQL to meet strict data residency regulations in Austria.
