From Strategy to Code

Services/Delivery & Engineering/AI & Data Engineering

LLM Integration & RAG Systems · Production AI Agents, Vector Search, Evals

Retrieval-augmented generation and LLM-powered features built for production — vector search, chunking strategy, evaluation, observability, and the guardrails that make non-deterministic systems defensible to legal, security, and finance.

Why HXRL

Our point of view

Most RAG demos work. Most RAG products in production drift, hallucinate, and produce results no one is accountable for. We instrument evals, log everything, and build the human-review loop in from day one — not as a 2.0 feature.

Outcome

AI features your legal, security, and CFO teams will defend — not just the engineering team.

What we ship

LLM Integration & RAG Systems

Concrete deliverables — not adjectives. Each engagement scopes which of these are in play and what success looks like for them.

02Retrieval pipelines with chunking and reranking
03Agent workflows (LangGraph, custom orchestration)
04Evals and observability (LangSmith, Helicone, custom)
05Guardrails (PII redaction, prompt-injection defence, output validation)
FAQ

Questions clients actually ask

Drawn from sales calls, not SEO filler. Want a question added? Drop it in the form on this page — we update from real enquiries.

Pinecone, Weaviate, or pgvector?+

pgvector when you already have Postgres and the corpus is small-to-mid. Pinecone for managed scale. Weaviate when you want hybrid search with first-class metadata. We benchmark for the actual workload.

How do you handle hallucinations?+

Citation-backed responses, retrieval gating, output schema validation, and human-review queues for high-stakes paths. Hallucination is a systems problem, not a model problem.

Evals — how seriously?+

CI-blocking. We build eval datasets early and gate releases on regression, the same way we gate on test failures.

Vendor lock-in to OpenAI?+

We architect for provider portability — usually via Vercel AI Gateway or a thin adapter — so swapping models or providers is a config change, not a rewrite.
