RAG & Knowledge Systems

Answers connected to their sources.

Make internal knowledge usable without asking people to search every folder. Retrieval-augmented generation combines relevant, permission-aware source material with an answer that points back to the evidence.

01 / THE BUSINESS PROBLEM

Built around the work that matters.

Company knowledge changes across PDFs, manuals, help centers, spreadsheets and operational records. A model’s general knowledge cannot tell you which internal policy is current or which records a user may access. A retrieval system needs document ownership, freshness and access control as much as embeddings.

02 / WHAT WE BUILD

The capabilities behind the experience.

A focused system with explicit responsibilities, useful interfaces and a maintainable implementation.

01 / CAPABILITY

Ingestion pipelines

Parse PDF, DOCX, help-center pages and approved database records. Preserve source IDs, headings, page references and update timestamps.

02 / CAPABILITY

Retrieval design

Choose chunk boundaries around meaning, combine lexical and vector search where useful, and evaluate reranking against representative questions.

03 / CAPABILITY

Permission boundaries

Filter authorized sources before generation. Carry document access rules through indexing, retrieval, citations and deletion.

04 / CAPABILITY

Grounded answers

Return traceable citations, distinguish conflicting sources and explain when the indexed material does not support an answer.

03 / SYSTEM ARCHITECTURE

Understand how the parts connect.

When this approach makes sense

Index quality is often the limiting factor. We test source coverage, version conflicts, retrieval recall and unanswered questions before tuning the final prompt. A confident answer without a supporting passage counts as a failure.

ENGINEERING NOTES

The details that make the difference.

Decisions that turn a promising prototype into a usable system.

Ingestion and document lifecycle

A pipeline parses supported sources, preserves structure and attaches source identifiers. Chunking follows headings, paragraphs and tables where practical. We track documents that fail to parse, update stale chunks when a source changes and remove material when access or retention requires it.

Retrieval, reranking and context

Vector retrieval finds semantically related passages; lexical search can help with exact product names and identifiers. A reranker may improve the selection, but it must be evaluated on your questions. We control context size and preserve enough surrounding material to avoid extracting a sentence that changes meaning in isolation.

A response that can be checked

The answer should distinguish supported statements from inference and acknowledge when sources are incomplete or contradictory. Citations point to the actual supporting material. We test permissions, citation accuracy and the system’s willingness to say that the source collection does not contain an answer.

05 / FROM DISCOVERY TO DELIVERY

Clear decisions. Reviewable progress.

We begin with your current workflow, representative inputs and the people responsible for the result. Together we define the first useful release, success criteria and dependencies such as API access, data preparation or external approval.

Architecture and prototyping address the uncertain parts before we commit to the full implementation. During development, we review complete user journeys with you and test both successful operation and expected failures.

The handover includes the agreed source, configuration and operating documentation. Deployment, ownership, third-party costs and ongoing support are made explicit in the project scope.

The full delivery process
06 / OPERATING WITH CONFIDENCE

Designed for the real environment.

Access and information

We identify what information the system needs and who is allowed to use it. Credentials stay on the server, permissions are enforced at the data boundary and sensitive inputs are kept out of routine logs. Provider access and retention behavior are assessed against your requirements before deployment.

Reliability and growth

We define expected load and failure conditions rather than promising unlimited scale. Timeouts, controlled retries, database constraints and observable job status make errors recoverable. Backups and rollback procedures belong in the delivery plan, alongside the code.

07 / INDUSTRY CONTEXT

08 / COMMON QUESTIONS

Before the build.

01

What should we bring to a rag & knowledge systems discussion?

Bring the current workflow, a few representative inputs, your existing systems and the result you want to improve. Index quality is often the limiting factor. We test source coverage, version conflicts, retrieval recall and unanswered questions before tuning the final prompt. A confident answer without a supporting passage counts as a failure.

02

Can you work with our existing software?

Yes. We first inspect the existing code, APIs, data and operational constraints. We preserve useful functionality and propose staged changes where a full replacement would add unnecessary risk.

03

How do you handle private business data?

We agree what data can be used, which services may process it and who can access the result. The design can include scoped credentials, permission-aware retrieval, data minimization, retention rules and audit logs. The final controls depend on your requirements and selected providers.

04

How long will our project take?

The schedule depends on scope, integrations, data readiness and acceptance requirements. After discovery, we propose milestones and identify external dependencies. We do not promise a fixed timeline before understanding the work.

05

Who owns the code and what happens after launch?

Ownership, licensing and handover are agreed in the project contract. A handover can include source code, deployment instructions and operating documentation. Support and ongoing improvement are scoped separately so responsibilities are clear.

06

How is a project priced?

We estimate from the agreed scope, complexity, integrations and delivery approach. Third-party usage and infrastructure costs are identified separately. The project planner provides a brief to discuss, not a binding quote.
