Services

Everything below is quotable at a fixed price.

Each band is an indicative starting point for a typical scope. The number that binds comes out of a two-week Discovery Sprint — and every service here lists what it does not include, because that is where fixed-price projects usually go wrong.

Custom Software Development

The systems that run your business but don't exist off the shelf — approval workflows, internal portals, scheduling engines, operations consoles.

Built to your actual process, including the parts of it that are strange.

What you get
  • Requirements and process mapping with the people who do the work
  • Role-based access, audit trails and reporting from day one
  • Automated regression covering your critical paths
  • Deployment to your cloud or ours, with a runbook

Web Application Development

Customer-facing products, dashboards and portals.

We agree the performance budget and the browser matrix in discovery, then we test against them — so "it's slow on mobile" is a build failure, not a post-launch surprise.

What you get
  • Component library and design system implementation
  • Server-side rendering or SPA, chosen on your SEO and latency needs
  • Accessibility to WCAG 2.2 AA, verified with automated and manual checks
  • Core Web Vitals budget enforced in the pipeline

Mobile App Development

iOS and Android from one codebase, dropping to native only where the platform genuinely demands it.

Store submission is part of the scope, not an afterthought you inherit.

What you get
  • Cross-platform build with native modules where required
  • Offline behaviour and sync strategy defined in discovery
  • Device-lab testing across a named device matrix
  • App Store and Play Store submission, including review responses

E-commerce Development

Storefronts, checkouts and headless commerce.

This is the category where our testing heritage earns its keep most obviously — a broken promo rule or a failed payment callback is money leaving the building on a schedule.

What you get
  • Catalogue, cart, checkout and payment integration
  • Promotions and tax rules tested against real edge cases
  • Peak-traffic load testing before your busiest day, not after
  • Order, inventory and fulfilment system integration

UI/UX & Product Design

Research, flows, wireframes and interface design delivered as a build-ready system — tokens, components and states, not a folder of screens that fall apart the moment an engineer opens them.

What you get
  • User research and journey mapping
  • Interactive prototype for stakeholder sign-off
  • Design system with tokens, components and documented states
  • Accessibility reviewed at design stage, not retrofitted

  • —Marketing collateral
  • —Illustration and custom photography

Cloud & DevOps

Infrastructure as code, containerised deploys and pipelines that gate on tests instead of on someone remembering to check.

If deploying is scary, that is a process defect and it is fixable.

What you get
  • Infrastructure defined in Terraform, reviewable in pull requests
  • CI/CD with parallel test execution and threshold-based gates
  • Observability: logs, metrics, traces and alerts that route somewhere
  • Cost review and right-sizing before handover

Data & Analytics

Pipelines, warehouse modelling and reporting layers, so the number in the board pack and the number in the operations dashboard come from the same place and agree.

What you get
  • Source system audit and ingestion pipelines
  • Dimensional model with tested transformations
  • Dashboards built with the people who'll use them
  • Data quality checks that alert when a feed goes wrong

AI & LLM Applications

Document automation, retrieval over your own content, and agents that touch real systems.

Scoped with an evaluation harness, so "is it good enough?" has a number attached instead of an opinion.

What you get
  • Use-case assessment — including saying no where it doesn't pay
  • Retrieval pipeline over your documents and data
  • Evaluation set and scoring harness, run in CI
  • Guardrails, cost controls and human-review paths

API & Systems Integration

Making the ERP, the CRM, the payment provider and the logistics platform agree with each other.

Contract tested on both sides, so an upstream change breaks a build rather than a customer's order.

What you get
  • Integration map and failure-mode analysis
  • API design or middleware layer with versioning
  • Contract tests running against both sides in CI
  • Retry, idempotency and reconciliation handling

Application Modernization

Legacy systems moved off end-of-life stacks in slices, with the old system live throughout.

We write characterisation tests around current behaviour first, so you can prove the replacement does what the original did.

What you get
  • Legacy assessment, dependency map and risk register
  • Characterisation tests capturing existing behaviour
  • Strangler-fig migration, one slice at a time
  • A repeatable pattern your team can run without us

Also available

Quality engineering, as a standalone service.

Testing is inside the price on every build we run. It's also a practice you can hire on its own — twenty-plus service lines, month-to-month, on a codebase we didn't write.
