From simple document Q&A to multi-source enterprise knowledge bases with role-based access — we cover every production RAG architecture with proven accuracy targets.
Discuss Your Project →Every layer of the RAG stack — from document ingestion to answer generation — owned by one team, delivered end-to-end.
Robust ETL pipelines that ingest your documents, apply intelligent chunking, extract metadata, and keep the index in sync.
The right vector store and embedding model for your scale and latency — evaluated and configured for your exact use case.
Naive cosine similarity gets 70% accuracy. Hybrid search, re-ranking, and query expansion get you to 90%+ reliably.
Source citation on every answer, confidence thresholds, and "I don't know" fallbacks — hallucination is a hard failure criterion.
Role-based document access, multi-tenant isolation, and full audit logging for sensitive enterprise deployments.
RAG systems degrade over time. We build feedback loops and monitoring to keep accuracy high as your content evolves.
Best-in-class tools chosen for performance, reliability, and team expertise — not hype.
A clear, collaborative process with no surprises and working demos at every milestone.
Map document sources, formats, update frequency, access controls. Define retrieval accuracy targets and build evaluation dataset.
Build ETL pipeline for all document types with chunking, metadata, embedding generation, and incremental update triggers.
Deploy and tune vector store, implement hybrid search, optimise chunk size and embedding model against your eval dataset.
Connect retrieval to your LLM with system prompt, citation formatting, confidence scoring, and fallback patterns.
Measure faithfulness, answer relevance, context precision, and recall. Iterate until accuracy targets are met.
Deploy with monitoring, quality degradation alerts, and a continuous improvement feedback loop.
No juniors, no mid-weight delegation. Every engineer on your project is 5+ years experience, senior by any measure.
We set Lighthouse 90+ as a non-negotiable acceptance criterion — not a target, a requirement. Deployments fail if CWV regress.
Unit, integration, and E2E tests as standard deliverable. We don't ship without coverage. No exceptions under deadline pressure.
Full system design — schema, API contracts, auth, deployment — documented and approved before any code is written.
WCAG 2.1 AA from component 1, not added at the end. Keyboard navigation, screen readers, colour contrast — non-negotiable.
End of every sprint, you get a live staging URL to click through. Not a Loom recording — a real deployed demo.
100% IP & code transfer. Your repo, your infra, your AWS account. Full documentation so your team can own it the day we hand over.
GA4, Mixpanel or Amplitude wired in before go-live. You launch with data, not waiting weeks to set up tracking after.
"They architected and built our entire web platform from scratch — real-time collaboration, complex permissions, WebSockets. Every edge case handled, zero bugs at launch."
"Our new storefront loads in 0.8s and converts at 3.2x our old Magento site. Every detail considered — mobile-first, accessibility, structured data. The results speak."
"From Figma to deployed in 8 weeks. Their React architecture thinking sets them apart from every agency I\"
"200K concurrent users on launch day — not a single outage. The infrastructure and caching strategy Nexcode built handled load I didn\"
"The real-time dashboard processes 1M+ events/day without a hiccup. Clean code, exceptional docs, and they explained every architectural decision. Extended the team afterward."
