Capability 02

Product engineering for systems that have to stay up.

We take ownership of architecture, not just tickets. Type-safe from database to browser, tested at the boundaries, instrumented on day one — and shipped in weeks rather than quarters.

Where custom builds usually break

If two or more of these sound familiar, the underlying issue is usually architectural rather than a shortage of effort. That is the part we are good at.

  • The system was fine at five thousand users and falls over at fifty thousand.
  • Every release is a manual ceremony only one engineer knows how to perform.
  • Business logic is duplicated across three services and disagrees with itself.
  • There are no types at the network boundary, so the frontend breaks silently.
  • The original contractor left and nobody can safely change the schema.
What we build

Five things we deliver inside this practice.

Each one is a complete piece of engineering, not a line item on a proposal.

Full-Stack Web Applications

Modern React and Next.js applications engineered for Core Web Vitals, accessibility, and a decade of maintenance.

  • App Router, server components, edge rendering
  • End-to-end type safety across the wire
  • Playwright coverage on revenue-critical paths
  • Interaction budgets enforced in CI

Custom Admin Dashboards & Portals

Internal tools and client portals that replace the spreadsheet your operations team quietly runs the company on.

  • Role-scoped views with full audit trails
  • Bulk operations with optimistic UI
  • Saved views, filters, and exports
  • Real-time updates without page reloads

CRM & ERP Solutions

Operations software shaped around how your business actually works, instead of forcing a rewrite of your process.

  • Custom pipelines, stages, and permissions
  • Inventory, billing, and fulfilment modules
  • Legacy migration with reconciliation checks
  • Reporting your finance team trusts

API Development & Integration

High-performance REST and GraphQL services, plus the integration work that makes third-party systems behave.

  • OpenAPI contracts and generated clients
  • Idempotency, pagination, and versioning done right
  • Rate limiting and backpressure
  • Retry and reconciliation for unreliable partners

SaaS MVP Development

A turn-key first version built to be extended — auth, billing, multi-tenancy, and analytics from the first commit.

  • Multi-tenant data model from day one
  • Billing with usage metering
  • Feature flags for staged rollout
  • Product analytics wired to activation

Delivery

How this engagement runs.

Named phases with named outputs. You always know what is being produced and when you will see it.

  1. P1Week 1

    Architecture sprint

    We map the domain, choose the data model, and write down the decisions with their trade-offs. You own that document whether or not you continue with us.

    Domain modelArchitecture decision recordsDelivery plan
  2. P2Week 2

    Vertical slice

    One real feature shipped end to end through the whole stack — auth, database, API, interface, tests, deploy — so the pipeline is proven before volume begins.

    Working slice in stagingCI/CD pipelinePreview environments
  3. P3Week 3-10

    Build in weekly increments

    Every Friday there is something in staging you can click. No month-long silences, no big-bang integration at the end.

  4. P4Pre-launch

    Load, harden, launch

    Load testing against realistic traffic shapes, query plan review, cache strategy, and a rollback path that has actually been rehearsed.

  5. P5Ongoing

    Handover or embed

    We either hand the system to your team with documentation and pairing sessions, or stay embedded as your engineering function.

What you receive

Every engagement ends with these in your accounts, whether or not we keep working together afterwards.

  • Source code and infrastructure you own outright
  • Architecture decision records
  • CI/CD with a preview environment per pull request
  • Tests covering critical business paths
  • Monitoring, alerting, and error tracking
  • Written onboarding guide for your next engineer

Questions we get asked

Completely. Everything lives in your repository and your cloud accounts from the first commit. There is no proprietary layer you have to keep paying us for.

Usually. We start with a paid audit that maps the system, grades risk, and gives an honest recommendation — including when the right answer is a targeted rewrite rather than more patching.

Types at every boundary, tests on the paths that lose money when they break, and a deploy pipeline where reverting is one click. Speed comes from confidence, not from skipping steps.

Let us talk about custom software engineering.

Two ways to start, both of them short. Bring the problem, not a specification — the first useful thing we do is tell you what we would build and roughly what it costs.

Book an architecture call

Fifteen minutes, no deck. We map your problem to an approach and tell you what a realistic scope and budget look like.

  • A specific technical recommendation
  • A budget band you can plan against
  • An honest answer if we are the wrong fit

Send a written brief

Prefer to write it down? Email us the shape of the problem and we will reply with a first take, usually under 12 hours.

  • Goes straight to an engineer, not a sales inbox
  • We reply with an approach, not a brochure
  • Attach anything: repos, docs, screenshots
