Our Approach

We build RAG systems with a clear set of engineering principles, a proven reference architecture, and technology choices that prioritize security, transparency, and maintainability.

Engineering principles

These principles guide every decision we make, from architecture design to technology selection.

Security by design

Security is built into every layer of the system, not added as an afterthought. Data never leaves your infrastructure, and access controls are enforced at every interaction point.

Transparency and explainability

Every response generated by the system can be traced back to its source documents. Users understand where information comes from and can verify accuracy.

Auditability

Complete logging of all system interactions, including queries, retrieved documents, and generated responses. Essential for compliance and continuous improvement.

Data sovereignty

Your data remains under your control at all times. No external API calls with sensitive information, no cloud dependencies for core functionality.

Modular architecture

Components can be replaced, upgraded, or customized independently. No vendor lock-in, no proprietary dependencies that limit your options.

Infrastructure agnostic

Deployable on your existing infrastructure, whether on-premise servers, private cloud, or hybrid environments. We adapt to your constraints.

Reference architecture

A layered architecture that separates concerns and allows independent scaling and customization of each component.

01

Data Ingestion

Document processing pipeline that handles various formats, extracts text, metadata, and structure. Includes quality validation and deduplication.

02

Embedding & Indexing

Converts processed text into vector representations and builds searchable indices. Supports multiple embedding models and indexing strategies.

03

Retrieval

Semantic search across your knowledge base with configurable relevance scoring. Supports filtering, reranking, and multi-stage retrieval.

04

Generation

LLM integration for response generation with retrieved context. Supports various models, including on-premise options.

Application

User-facing interfaces and API endpoints. Includes authentication, authorization, and integration capabilities.

Technology stack

We use proven, well-documented technologies that your team can understand, maintain, and extend.

Embedding Models

  • -Sentence Transformers
  • -E5 / BGE models
  • -Instructor embeddings
  • -Custom fine-tuned models

All models can run on-premise without external API calls.

Vector Databases

  • -Qdrant
  • -Milvus
  • -Weaviate
  • -pgvector

Selected based on scale requirements and existing infrastructure.

Language Models

  • -Llama 3 / Mistral (on-premise)
  • -Claude / GPT (where permitted)
  • -Fine-tuned domain models

Model selection depends on regulatory constraints and performance requirements.

Infrastructure

  • -Docker / Kubernetes
  • -PostgreSQL
  • -Redis
  • -Prometheus / Grafana

Designed to integrate with your existing operations tooling.

Development

  • -Python
  • -LangChain / LlamaIndex
  • -FastAPI
  • -React / Next.js

Standard technologies that your team can maintain.
