How agents reason

The ReAct loop the core pattern behind every agent we build.

01

Custom Platform Engineering

Domain-Driven Enterprise Platform Development

Business-critical platforms designed around your actual domain model not a generic ERP configured to approximate one. We start with event storming and domain modelling before a line of code is written, producing bounded contexts with clear ownership, independent deployment, and data autonomy. The architecture accommodates future complexity; it doesn’t just solve today’s problem.

◆ Design method

Domain-Driven Design (DDD) · event storming · context mapping.

◆ Data pattern

Database-per-service · CQRS · event sourcing where warranted.

◆ Deployment

Independent per bounded context · canary releases · feature flags.

◆ Observability

Structured logging · distributed tracing · SLO-based alerting.
 

02

Integration Architecture

Event-Driven Integration & API Management

Enterprise complexity lives in the integration layer. We design it as a first-class architectural concern API-first interfaces, event-driven service communication, and an explicit integration topology with documented data contracts. Not point-to-point connections that create invisible coupling and breaking changes. The integration layer is observable, versioned, and independently deployable.

 

◆ Ingress pattern

API gateway (Kong / AWS API GW) · rate limiting · circuit breaking
 

◆ Internal comms

Kafka event bus · consumer groups · exactly-once semantics

◆ Data contracts

Avro / Protobuf schemas · schema registry · consumer-driven testing

◆ Legacy bridge

Anti-corruption layer (ACL) · change data capture · adapter pattern.

03

Platform Engineering

Cloud-Native Architecture & Internal Developer Platform

Decomposed, independently deployable services on Kubernetes with the platform engineering discipline to run them reliably. Service mesh for east-west observability and mutual TLS. An internal developer platform that reduces cognitive load so product teams ship without needing infrastructure expertise. GitOps for every environment. SLOs, not alerts.

◆ Container platform

Kubernetes (EKS / AKS / GKE) · Helm · Kustomize
 

◆ Service mesh

Istio · mTLS · traffic shaping · circuit breaking · Envoy proxy

◆ GitOps

ArgoCD · Terraform · Crossplane · infrastructure as code

◆ Platform layer

Backstage IDP · service templates · golden paths · runbooks.
 

04

AI Engineering

AI & LLM Integration as First-Class Architecture

AI embedded as specific, versioned functional components within enterprise systems not a wrapper around a model API bolted to a UI. Decision engines at approval steps. LLM pipelines replacing document data entry. RAG systems over enterprise knowledge bases. AI agents orchestrating exception workflows. Each component exposes a clear interface, is versioned independently, and has its own drift monitoring and rollback path.

◆ LLM integration

OpenAI API · Anthropic Claude · Bedrock · Azure OpenAI · Vertex AI

◆ RAG architecture

LlamaIndex / LangChain · Pinecone / Weaviate · semantic chunking

◆ Agents

LangGraph · AutoGen · tool-use patterns · human-in-loop checkpoints

◆AI MLOps

MLflow · LangSmith · Evidently AI · shadow deployment · A/B evals

05

Modernisation Engineering

Legacy Modernisation & Zero-Downtime Migration

Replacing production enterprise systems without business disruption requires a migration strategy, not a rewrite plan. Strangler fig pattern new capability built as modern services, traffic migrated incrementally, legacy decommissioned when redundant. Before any code is written, AI-assisted analysis of the legacy codebase surfaces undocumented business logic, high-risk components, and missing test coverage the knowledge that would be lost without it.

◆ Migration pattern

Strangler fig · branch-by-abstraction · parallel run · dark launch

◆ Code analysis

AI-assisted legacy analysis · GitHub Copilot Enterprise · SonarQube

◆ Data migration

CDC with Debezium · dual-write pattern · zero-downtime schema changes

◆ Test safety net

AI-generated test coverage · characterisation tests · contract tests

06

Portal & Workflow Engineering

Enterprise Portals, Workflow Platforms & Automation

Self-service portals and workflow platforms that give every stakeholder employees, suppliers, partners, customers the right access to the right processes, with full audit trails and role-based controls. Built on event-driven foundations so workflows compose rather than fragment. AI embedded at decision and triage points to reduce manual intervention without removing human accountability.

◆ Frontend

React / Next.js · micro-frontend architecture · design system

◆Workflow engine

Temporal · Camunda · custom state machine · event-driven orchestration

◆Access control

Attribute-based access control (ABAC) · audit log · SSO / SAML

◆ AI at workflow

Decision engines at approval steps · LLM document handling · agents

AI integration patterns

patterns for embedding AI in enterprise systems.

AI Patterns Grid
Pattern 01 · Decision Engine
ML Model at Approval Workflow
ML model exposed as an internal service. Called synchronously at decision points purchase approval, credit assessment, resource allocation. Returns a scored recommendation; human retains the decision authority.
// approval-workflow.ts const decision = await aiDecisionSvc.score({ context: "purchase_approval", payload: orderRequest, threshold: 0.85 }); if (decision.confidence < threshold) await workflow.routeToHuman(decision);
Pattern 02 · RAG Pipeline
LLM over Enterprise Knowledge Base
Documents, policies, and system data chunked, embedded, and stored in a vector database. LLM retrieves relevant context at query time. Answers are grounded in current enterprise data, not model training data.
// enterprise-rag.py chunks = retriever.query( query=user_question, k=8, filter={"domain":"procurement"} ) response = llm.generate( system=GROUNDING_PROMPT, context=chunks, user=user_question )
Pattern 03 · Document Intelligence
LLM Extraction Replacing Data Entry
Unstructured documents invoices, contracts, reports passed through an LLM extraction pipeline. Structured output validated against a schema, confidence-scored, and routed: high-confidence auto-posted; low-confidence to human review queue.
// document-extraction.ts const extracted = await docAI.extract({ document: pdfBuffer, schema: InvoiceSchema, model: "claude-sonnet-4-6" }); if (extracted.confidence > 0.92) await erp.postInvoice(extracted.data); else await reviewQueue.push(extracted);
Pattern 04 · Agentic Workflow
AI Agent Handling Exception Orchestration
LLM agent monitors exception queues, gathers context using tools (database queries, API calls, log searches), attempts resolution within confidence bounds, and escalates with a full brief when escalation is warranted.
// exception-agent.py agent = ExceptionAgent( tools=[db_query, api_call, log_search], escalation_threshold=0.7, max_steps=12 ) result = await agent.handle(exception) if result.status == "escalated": notify.engineer( brief=result.context_summary )
