Services

Engineering services for companies that depend on their software.

We are engaged where the software is the business: platforms that carry revenue, operations and compliance. Each service below is delivered with architecture documentation, review discipline and a support path.

Enterprise services

Capabilities built for systems that cannot fail quietly.

Six practices, one standard. Senior engineers scope, review and document every engagement, with clear ownership from architecture through support.

Custom software architecture design

We define the system before writing the product. Domain boundaries, data ownership, failure behaviour and scaling paths are decided early so the platform still makes sense three years and four teams later.

  • Domain-driven design
  • Documented decision records
  • Load and failure modelling

AI & LLM integrations

Applied AI with an engineering spine: retrieval pipelines grounded in your own data, evaluated prompts, cost controls and clear guardrails. No demos that collapse in production.

  • RAG over private corpora
  • Evaluation harnesses
  • Cost and latency budgets

Enterprise ERP & CRM

Operational backbones for companies that run on their software. Inventory, finance, pipeline and service are modelled to your process instead of forcing your process into a template.

  • Process modelling
  • Integration layers
  • Role-scoped permissions

Native & cross-platform mobile

Swift and Kotlin where the platform demands it, React Native and Flutter where velocity wins. Offline behaviour, release pipelines and store compliance handled as first-class work.

  • iOS & Android native
  • Offline-first sync
  • Automated release pipelines

Legacy system modernization

We migrate critical systems without stopping the business: measured strangler-fig transitions, parity testing against the old behaviour, and rollback available at every step.

  • Incremental extraction
  • Behaviour parity tests
  • Zero-drama cutovers

Cloud, security & long-term support

Infrastructure as code, zero-trust access, observability from day one, and maintenance agreements that keep the system healthy long after launch day.

  • Zero Trust access
  • Observability & alerting
  • Long-term support contracts

How we work

A predictable path from problem to production.

No mystery process. Every engagement follows the same four phases, with visible artefacts at each one.

Discovery & architecture

We map the business process, constraints and integration surface, then publish the architecture we intend to build.

Iterative delivery

Short cycles against a working system, with review, tests and staging environments on every change.

Hardening & launch

Performance, security and accessibility passes, observability wired in, runbooks written before go-live.

Long-term partnership

Support agreements, roadmap sessions and continued engineering as the business evolves.

Let's scope the system properly.

Tell us what the system has to achieve. We will tell you honestly what it takes, what it involves and how we would build it.
