Custom Software Engineering

Platforms that survive contact with real users.

We build the systems companies run on: customer portals, operations platforms, marketplaces, billing engines, internal tooling and the APIs that hold them together.

The brief is almost always the same — replace something brittle without stopping the business. So we work in strangler patterns, ship behind flags, and instrument everything before we change it. Migration risk is a design problem, and we design for it from week one.

Every codebase we hand over comes with tests that mean something, infrastructure defined as code, runbooks for the three most likely incidents, and a README a new hire can follow on their first morning.

Capabilities

What this practice actually covers.

01

Product & platform engineering

Full-stack delivery on a modern TypeScript foundation — server components, streaming, edge runtimes — with a design system that keeps the twentieth screen as consistent as the first.

  • Next.js 16, React 19, TypeScript strict mode end to end
  • Design-system-driven UI with accessibility to WCAG 2.2 AA
  • Multi-tenant architecture, RBAC and audit trails
  • Internationalisation and multi-currency where you need it
02

API & integration engineering

Most business value sits in the seams between systems. We design contract-first APIs and build the integration layer that keeps your ERP, CRM, payment and logistics tools honest.

  • REST, tRPC and GraphQL with generated, versioned clients
  • Event-driven integration — queues, webhooks, idempotency, replay
  • ERP/CRM connectors: SAP, Dynamics, HubSpot, Salesforce
  • Legacy adapters and anti-corruption layers for old systems
03

Data & backend architecture

Schema design, query performance and migration safety are where platforms quietly die. We treat the database as a product surface, not an implementation detail.

  • Postgres modelling, indexing strategy and query budgets
  • Reversible migrations with expand/contract deployment
  • Read replicas, caching layers and background job pipelines
  • Analytics pipeline and warehouse feeds from day one
04

Cloud, DevOps & reliability

Infrastructure as code, environments that match, and deployments boring enough to do on a Friday. Plus the monitoring you need to sleep afterwards.

  • Terraform-defined infrastructure on AWS, Cloudflare or Vercel
  • CI/CD with preview environments per pull request
  • OpenTelemetry tracing, structured logs, SLOs and alerting
  • Disaster-recovery plan with tested restore procedures
05

Modernisation & rescue

Half our software work starts with a system somebody else built. We stabilise first, document what exists, then replace it piece by piece while the business keeps running.

  • Technical due diligence with a costed remediation plan
  • Strangler-fig migration behind feature flags
  • Test harness retrofit before any refactor begins
  • Performance and cloud-cost optimisation audits
06

Quality engineering

Tests are a delivery-speed feature, not a compliance chore. We build the pyramid that lets a small team ship daily without fear.

  • Unit, integration and end-to-end suites in CI on every commit
  • Contract tests across service boundaries
  • Load and soak testing against realistic traffic shapes
  • Accessibility and visual-regression checks in the pipeline

Deliverables

What lands in your account.

  • Production platform, source code and full CI/CD pipeline
  • Architecture decision records and system diagrams
  • Infrastructure as code with reproducible environments
  • Test suites, load-test results and performance budgets
  • Operational runbooks, dashboards and on-call playbook

  • TypeScript
  • Next.js 16
  • React 19
  • Node.js
  • tRPC
  • Postgres

Chosen per engagement, not by habit. If your team already runs something else and it works, we work in it rather than around it.

Staffed by

Every engagement in this practice is delivered by a named team you interview yourself — designed, hired and led through our team-building practice.

FAQ

Questions about this practice.

Ask us directly
Do you work on existing codebases?
Frequently. We start with a two-week technical due diligence: what exists, what is risky, what it would cost to fix versus replace. You get the report whether or not you continue with us.
Who owns the code?
You do, from the first commit. Work happens in your repository under your organisation, or in ours with mirrored access and a transfer at any milestone you choose.
Can you work with our in-house engineers?
Yes, and it is usually the better outcome. We pair, review each other's pull requests, and share the same definition of done. See our dedicated teams practice for how we structure that.
