# Services

**Summary:** Six AI consulting services, each with a defined scope and a stated price band.

## RAG system design & build

Rubra builds production retrieval-augmented generation systems: document ingestion and parsing, chunking and embedding strategy, hybrid retrieval with reranking, grounded generation, and an evaluation harness that proves accuracy before launch. Typical engagements run 8–14 weeks and deliver a system your own engineers can operate.

- Duration: 8–14 weeks
- From: from €65,000
- Team: Two engineers plus a fractional architect

## LLM evaluation & QA

Rubra builds LLM evaluation systems: labelled test sets drawn from real usage, task-specific metrics for retrieval and generation quality, LLM-as-judge pipelines calibrated against human raters, and regression gates in CI. The result is that every prompt, model or retrieval change ships with evidence rather than a hunch.

- Duration: 4–8 weeks
- From: from €38,000
- Team: One senior engineer plus an evaluation specialist

## AI agent engineering

Rubra builds LLM agent systems that take actions rather than just answering questions: tool and API integration, multi-step planning, state management, human approval checkpoints, and full execution tracing. I am deliberately conservative about where agents belong, because most tasks marketed as agentic are better served by a deterministic workflow.

- Duration: 10–16 weeks
- From: from €75,000
- Team: Two engineers plus a fractional architect

## LLMOps & AI platform

Rubra builds the platform layer beneath AI features: a model gateway with failover, prompt and config versioning, distributed tracing, per-team cost attribution and budgets, semantic caching, and deployment pipelines with evaluation gates. It is what turns three separate AI prototypes into a capability the whole organisation can build on.

- Duration: 6–12 weeks
- From: from €55,000
- Team: One platform engineer plus a fractional architect

## EU AI Act readiness

Rubra helps organisations classify their AI systems under the EU AI Act, identify obligations by risk tier, and produce the technical evidence the regulation requires: risk management records, data governance documentation, accuracy and robustness testing, logging, and human oversight design. I cover the engineering half; I work alongside your counsel on the legal half.

- Duration: 5–10 weeks
- From: from €42,000
- Team: One AI architect plus a governance specialist
- Full page: https://rubradigital.com/services/eu-ai-act-compliance

## AI strategy & discovery

Rubra runs three to five week AI discovery engagements that produce a ranked portfolio of use cases with feasibility assessments, cost and effort estimates, data readiness findings, and a sequenced roadmap. The most valuable output is usually the list of things I recommend you do not build.

- Duration: 3–5 weeks
- From: from €22,000
- Team: One principal consultant plus an AI architect
