Domain-Driven System Shape

Align system boundaries to business domains so that architecture reflects organisational intent.

Domain-Driven System Shape is the practice of using domain modelling techniques to define service boundaries, data ownership, and team topology. Rather than letting technical convenience dictate architecture, we work with domain experts to discover bounded contexts and design systems whose shape mirrors the business they serve.

Key Features

Bounded Context Discovery

Facilitated domain modelling workshops that identify natural service boundaries, aggregate roots, and context maps through Event Storming and domain storytelling.

Context Mapping & Integration Patterns

Explicit modelling of upstream/downstream relationships, anti-corruption layers, and shared kernels so that inter-service contracts are intentional rather than accidental.

Ubiquitous Language Codification

A living glossary and naming convention framework that ensures domain terminology is consistent across code, APIs, data schemas, and team communication.

Team Topology Alignment

Mapping bounded contexts to team ownership boundaries, reducing cross-team coupling and enabling autonomous delivery within well-defined domains.

Use Cases

Core Banking Decomposition

Banking

A digital bank needed to decompose a monolithic ledger into domain-aligned services for accounts, payments, and lending without disrupting live operations.

Insurance Product Platform

Insurance

An insurer building a new product platform required clear domain boundaries between underwriting, claims, and policy administration to enable parallel team delivery.

Marketplace Domain Restructuring

Technology

A B2B marketplace with tangled service dependencies used domain-driven analysis to untangle order management, inventory, and fulfilment into independently deployable domains.
