RAG & LLM Engineering

Retrieval and reasoning over your data, including on-premise.

Retrieval-augmented generation, fine-tuning, and on-premise model engineering. Strong angle for regulated and sovereign workloads where data cannot leave the estate.

Where this goes wrong

The patterns we are most often called in to fix.

Pattern 01

RAG demos that collapse the moment they meet a real corpus.

Pattern 02

Sensitive data that legally cannot be sent to a hosted LLM provider.

Pattern 03

No way to measure whether a retrieval system is getting better or worse.

Our process

How we deliver: Discover, Architect, Build, Run

  1. 01

    Discover

    Frame the problem with the people closest to it. Map the system. Surface the assumptions and the unknowns.

  2. 02

    Architect

    Design the target state and the path to it. Make the trade-offs explicit. Earn buy-in across engineering, security, and the business.

  3. 03

    Build

    Cross-functional delivery with a definition of done that includes observability, security, and runbooks, not just feature acceptance.

  4. 04

    Run

    Operate with you. Continuous improvement against business outcomes, with FinOps and AI-augmented DevOps baked in.

What’s in scope

The capabilities you draw on across an engagement.

  • Corpus engineering: extraction, chunking, embedding strategy
  • Vector database selection, hybrid search, re-ranking
  • On-premise and air-gapped deployments of open-source LLMs
  • Evaluation harnesses, golden sets, and continuous regression testing
  • Fine-tuning and parameter-efficient adaptation (LoRA / QLoRA)
  • Model-agnostic orchestration across hosted and local providers

Technology footprint

We are pragmatic about technology, and AI-agnostic by default.
