Naive chunking strategy
Fixed-size chunks split context mid-sentence, so retrieval returns fragments that miss the point.

We build retrieval-augmented generation applications—knowledge search tools, research copilots, and document intelligence apps—engineered around real ingestion pipelines, tuned retrieval, and evaluation harnesses that catch hallucination before users do.

About Our RAG Practice
An Evaluation-Led RAG Engineering Partner
Not a prompt-and-pray demo.
ShubhDigi builds RAG applications as evidence systems: ingestion pipelines that chunk and embed your content sensibly, retrieval tuned for precision over recall, and interfaces that show users exactly which source backs each answer.
We treat retrieval-augmented generation as an application architecture discipline, not a single API call—chunking strategy, embedding model choice, hybrid search, and reranking all get evaluated against your actual content before anything ships.
From data audit through evaluation and phased rollout, you work with one accountable engineering team that measures accuracy with real test sets and documents the retrieval logic your team can maintain going forward.
Retrieval quality first
Chunking, embeddings, and reranking tuned against your content before the LLM prompt is finalized.
Citations are not optional
Every grounded answer traces to a retrievable source so users can verify, not just trust.
Evaluate before you scale
Real test sets and accuracy metrics gate launch—not vibes from a good demo session.
Application architecture, not a wrapper
Ingestion, indexing, retrieval, and UI designed as a coherent system your team can operate.

Demo-only AI wrappers
A slick chat UI over an unevaluated vector search that quietly drifts wrong.
RAG application engineering
Ingestion pipelines, tuned retrieval, citation UI, and eval harnesses built to survive real usage.
RAG delivery cycle
Audit data → architect retrieval → build → evaluate → launch → monitor
RAG Application Friction Points
RAG projects stall when
retrieval quality is assumed, not measured.
Teams ship a demo fast on default chunking and a vector store—then hit walls on relevance, hallucination, and no way to prove accuracy.
Retrieval that misses relevant content
Pure vector similarity search alone often surfaces near-matches instead of the actually relevant passage.
No evaluation before launch
Teams ship on demo confidence with no test set to catch systematic retrieval or generation failures.
Uncited, unverifiable answers
Without source citations, users cannot tell a grounded answer from a confident hallucination.
Stale knowledge indexes
Source documents change but the vector index does not, so answers quietly go out of date.
Cost and latency surprises
Unoptimized retrieval and oversized context windows blow up token costs and response times at scale.

How We Build RAG Applications
A path from raw content to
evaluated, trustworthy answers.
Eight steps with clear durations—retrieval architecture decided early, evaluated before launch, monitored after.
STEP 01
Data & Source Audit
Inventory content sources, formats, and access permissions that will feed the retrieval layer.
STEP 02
Retrieval Architecture
Decide chunking strategy, embedding model, vector store, and hybrid search approach.
STEP 03
Ingestion Pipeline Build
Build parsing, chunking, and embedding pipelines for your actual document and data sources.
STEP 04
Application Engineering
Build the retrieval-grounded application UI, including citation display and feedback capture.
STEP 05
Evaluation Harness
Build test sets from real queries and measure retrieval precision and answer accuracy.
STEP 06
Guardrails & Tuning
Tune retrieval parameters and add refusal or escalation logic where confidence is low.
STEP 07
Phased Rollout
Launch to a limited audience, monitor accuracy metrics, then expand scope with evidence.
STEP 08
Accuracy Monitoring
Ongoing evaluation, knowledge sync, and retrieval tuning as content and usage evolve.

Platform Capabilities
What production RAG applications
need under the hood.
Twelve capabilities that keep retrieval accurate, answers grounded, and applications operable over time.
01Ingestion
Content-aware chunking
Chunking strategy matched to document structure instead of arbitrary fixed-size splits.
02Retrieval
Embedding model selection
Model choice evaluated against your domain content rather than defaulted by habit.
03Retrieval
Hybrid search & reranking
Combining vector similarity with keyword and metadata filters, then reranking for precision.
04Security
Permission-aware retrieval
Access control enforced at query time so users only retrieve content they are allowed to see.
05Trust
Citation-grounded responses
Every generated answer links back to the retrieved source for user verification.
06Safety
Confidence-based escalation
Low-confidence retrieval triggers a refusal or human handoff instead of a guessed answer.
07Evaluation
Evaluation test sets
Real query and answer pairs used to measure retrieval and generation accuracy over time.
08Evaluation
Regression monitoring
Automated checks that catch retrieval quality drops when content or models change.
09Freshness
Knowledge sync pipelines
Automated re-indexing so retrieval stays current as source documents change.
10Architecture
Multi-source federation
Unified retrieval across documents, databases, and APIs behind one grounded interface.
11Performance
Cost-aware context assembly
Context window sizing and caching that balance answer quality against token spend.
12Growth
Usage & feedback analytics
Query logs and thumbs-up/down feedback that inform retrieval tuning with real evidence.
RAG Domains We Build
Applications shaped by how
each domain manages knowledge.
Content sensitivity and query patterns differ by domain—we encode them into retrieval architecture.
