AI Agent Systems

Purpose-built AI agents for operations — not proof-of-concept demos.

AI agents are not chatbots. A well-designed agent system can handle the operational load of two to five full-time employees on structured, repeatable tasks — document classification, email routing, form processing, customer triage.

The difference between a proof-of-concept agent and a production agent is reliability. A POC gets demoed once. A production agent runs 50,000 times a month, handles edge cases gracefully, escalates correctly when it is uncertain, and produces an audit trail that satisfies a compliance team.

We build on Azure AI Foundry with GPT-4o and Phi-4-mini for cost-appropriate routing. Every agent has a defined escalation path and a logged output. Nothing acts autonomously on regulated decisions.

What we deliver

  • Agent architecture with tool definitions and escalation paths
  • Human-in-the-loop design for all regulated decisions
  • Audit log for every agent action and decision
  • Accuracy benchmarks and confidence thresholds
  • Monitoring dashboard with anomaly alerts
  • Rollback procedure and override mechanism

Use cases

Where this applies.

Document processing agents
Insurance claims, mortgage applications, medical referrals. Agents extract, classify, and route — humans review and decide. Processing time from hours to minutes.
Customer triage and routing agents
Inbound queries classified, enriched with account context, and routed to the correct team before a human reads them. Escalation on low-confidence scores.
Internal operations agents
Onboarding checklists, compliance reminders, report generation. Structured operational tasks handled by agents that know when to ask for help.
