RAG Stack
Hybrid Search & Reranking
We improve retrieval quality for RAG and search systems using hybrid search, reranking, and query strategies—validated with evaluation sets so results are measurable and stable. Delivery aligned to Canada teams (PRO).
Start with evidence
Begin with a focused opportunity sprint
In 1–2 weeks, we map one consequential operation, test its automation case, and define a governed implementation plan before a larger build.
Standard
AI delivery standard
Quality and safety practices we ship with AI builds so the system stays measurable, maintainable, and production-ready.
Logging + tracing
Conversation and tool traces with request IDs, error visibility, and debug-friendly runbooks.
Guardrails + safety
Tool allowlists, PII-safe patterns, refusal behavior, and escalation routes for edge cases.
Evals + regression tests
Golden queries, scorecards, and regression checks so quality improves over time instead of drifting.
Cost + latency controls
Caching, prompt discipline, retrieval tuning, and routing so your app stays fast and predictable at scale.
Documentation + handoff
Architecture notes, environment setup, and next-step roadmap so your team can iterate safely after launch.
Security-first integration
Secrets isolation, role-based access, audit-friendly actions, and minimal data retention by design.

Features
What we deliver
Hybrid retrieval configuration
Combine keyword and semantic retrieval and tune weights based on your query distribution.
Reranking
Rerank candidate results for higher precision, especially in dense corpuses and ambiguous queries.
Query strategies
Query rewriting, metadata filters, and structured retrieval strategies for better relevance.
Evaluation sets
Golden queries and scoring to measure improvements and prevent regressions over time.
Snippet and citation UX
Better snippet selection and citations so users can verify results quickly.
Monitoring and iteration
Ongoing telemetry and feedback loops for continuous search quality improvements.

Upgrade product documentation search
Improve precision for exact terms, error codes, and feature names.
Internal knowledge search
Help teams find answers faster with ranked results and permission-aware filtering.
Sales enablement search
Find the right content and messaging quickly without misinformation.
Compliance and policy search
Improve relevance and traceability for policy-heavy corpuses where accuracy matters.
Implementation Patterns
How we frame common AI workflows
Illustrative patterns only—not client case studies, endorsements, or production-result claims.
Regulated mobile data workflow pattern
Challenge: Sensitive data workflows need explicit access boundaries, traceability, and documented operating responsibilities.
Approach: Threat-model the workflow, map authorization rules, select encryption controls, and define auditable state transitions.
Validation: Test access boundaries and recovery paths, record residual risk, and obtain any required independent compliance assessment.
Large knowledge-base retrieval pattern
Challenge: Long, mixed-format source collections need traceable retrieval and safe behavior when evidence is weak.
Approach: Evaluate hybrid retrieval, reranking, citations, structured outputs, and defined fallback or human-review paths.
Validation: Use a representative offline evaluation set and report citation quality, latency, and cost under documented test conditions.
Operations automation pattern
Challenge: Approval and system-sync workflows need deterministic controls around exceptions, retries, and ownership.
Approach: Model the workflow, add validation and approval gates, and use AI only for bounded classification or extraction tasks.
Validation: Baseline manual steps, test exception paths and audit logs, then compare pilot measurements before considering wider rollout.

FAQ
Frequently asked questions
Not always, but it often improves precision for exact terms and short queries. We validate with evaluation sets before recommending a final approach.
Reranking is often the biggest accuracy unlock for production retrieval, but it adds cost. We recommend based on evaluation results and budget constraints.
We define golden queries and scoring criteria, then track metrics over time to ensure quality improves and stays stable.
Reranking can add latency. We design for performance by tuning candidate sizes, caching, and choosing cost-effective ranking strategies.
Yes. Hybrid retrieval and reranking can be implemented across common vector stores and search backends.
Yes. Search UX (snippets, filters, citations) is often as important as retrieval quality for user trust.

Delivery considerations for your region
Data and risk discovery (Canada)
Privacy, security, residency, and regulatory requirements differ by workflow. We document the applicable data flows, roles, retention needs, and control owners before recommending an architecture.
The resulting proposal lists the controls and evidence that are actually in scope. It is not a generic compliance, certification, or legal-assurance promise.
- Map data sources, destinations, roles, and sensitive fields
- Record access, retention, logging, and deletion requirements
- Identify required security or procurement evidence before contracting
- Use an NDA or DPA only when the parties mutually execute it
Working model (Canada)
Exact live-overlap hours, response expectations, meeting windows, and escalation contacts are confirmed in the proposal for each engagement.
Written decisions, scoped milestones, and asynchronous updates reduce unnecessary meetings without implying an unagreed service level.
- Proposal-specific overlap and meeting windows
- Named owners for decisions and blockers
- Written scope, assumptions, and change decisions
- Milestone cadence agreed before kickoff
Commercial setup (Canada)
The contracting entity, proposal currency, invoicing cadence, payment terms, intellectual-property terms, and required vendor documents are agreed before work begins.
The Opportunity Sprint can establish the evidence needed to scope a production pilot; it does not pre-commit either party to a rollout.
- Contracting entity and currency confirmed in writing
- Milestones and acceptance criteria defined in the proposal
- Vendor-document requirements identified before signature
- Scope changes require an explicit written decision
Delivery controls (Canada)
Testing, observability, release, security, and handover controls are selected for the actual system risk rather than promised as a generic bundle.
Acceptance measures and production responsibilities are recorded before implementation so both teams know what evidence will support release.
- Risk-based testing and acceptance measures
- Release, rollback, and observability responsibilities
- Security controls tied to the agreed threat model
- Handover artifacts defined in the signed scope
