Built around the difficult parts.

01 / Systems

Backend and
distributed systems

We design and implement services with clear responsibilities for data, concurrency, and failure handling. For asynchronous workflows, that includes durable processing, retries, replay, and protection against duplicate operations.

In practice: service implementation, processing contracts, data boundaries, and tests for expected and exceptional behaviour.

02 / Connections

APIs, integration
and modernisation

We connect applications through explicit interfaces and documented contracts. We address compatibility, data mapping, authentication boundaries, and failure behaviour, including where existing systems need to evolve incrementally.

In practice: interface specifications, integration code, contract tests, migration decisions, and handover documentation.

03 / Decisions

Architecture
and specification

We work from business workflows and concrete examples to define useful system behaviour. Architecture decisions account for dependencies, operating constraints, and the changes a system needs to accommodate.

In practice: workflow models, requirements, design decisions, acceptance scenarios, and a traceable delivery scope.

04 / Operation

Delivery and
operational reliability

We consider how software is built, deployed, observed, and recovered. Technical assessments can examine performance, operational signals, configuration, and failure paths, with improvements scoped to the system's needs.

In practice: repeatable build workflows, deployment configuration, telemetry, diagnostic findings, and operational documentation.
