How we engineer

A method you can hold us to.

Confidence should come from a process you can inspect, not from adjectives on a website. This page sets out exactly how an engagement runs, what leaves each stage, and the standards applied whether the work is a firmware bring-up or a distributed platform.

The five stages

Every engagement, same shape

Scaled to the size of the work — a two-week review compresses these into days, a multi-month build gives each its own phase — but never skipped. You always know which stage we are in and what has to exist before it closes.

  1. 01

    Frame

    Establish what is actually being solved before anyone writes code.

    We separate the requirement from the proposed solution, identify the constraints that are genuinely fixed from the ones that are merely habitual, and name the risks that could invalidate the whole approach. Projects rarely fail in the build; they fail here, and find out in the build.

    What leaves this stage

    • Problem statement and success criteria
    • Constraint register — technical, regulatory, commercial
    • Risk list with the mitigations that matter
    • A go / no-go recommendation, including "do not build this"
  2. 02

    Design

    Make the expensive decisions deliberately, and write down why.

    Boundaries, contracts, data ownership, failure modes and capacity. Every significant choice becomes an Architecture Decision Record capturing the options considered and the consequences accepted — so in two years the reasoning is on paper rather than in somebody’s memory.

    What leaves this stage

    • Architecture description (C4 or equivalent)
    • Interface and contract definitions
    • Architecture Decision Records
    • Capacity model and performance budget
    • Threat model and security review
  3. 03

    Build

    Working software at every step, never an integration cliff at the end.

    Small reviewable increments behind automated verification. Trunk-based development with short-lived branches, CI that runs the full gate on every change, and a deployable artefact from day one. You see progress continuously rather than at a milestone review.

    What leaves this stage

    • Reviewed, tested, documented source
    • CI pipeline with the full quality gate
    • Reproducible builds and signed artefacts
    • Demonstrable increments on a fixed cadence
  4. 04

    Harden

    Break it while breaking it is still cheap.

    Load and soak testing to the design ceiling, deliberate fault injection, power-loss and failover testing where relevant, security review and dependency audit. The goal is to find the failure modes in a test rig rather than in an incident channel.

    What leaves this stage

    • Performance characterisation with methodology
    • Fault injection and failover results
    • Security review findings and remediation
    • Known limitations, stated plainly
  5. 05

    Hand over

    Leave you able to operate it without us.

    Documentation aimed at the person who will be on call, runbooks for the failure modes we know about, telemetry and alerting already in place, and working sessions with your team. An engagement that leaves a client dependent on us has failed, regardless of whether the software works.

    What leaves this stage

    • Operations and architecture documentation
    • Runbooks and incident playbooks
    • Dashboards, SLOs and alerting
    • Knowledge transfer sessions and a support window

Engineering standards

The bar, regardless of the project

These are not aspirations. They are the conditions under which we agree to do the work, and they apply on a two-week intervention exactly as they do on a twelve-month build.

  • Code review is not optional

    Every change is reviewed by a second engineer against a defined bar: correctness, failure handling, test coverage of the new path, and whether the next person can understand it. Bootloader, cryptography and forwarding-path changes get a higher bar again.

  • Tests that test the risky part

    Unit tests for logic, contract tests at every boundary, property-based tests for state machines and protocol code, and integration tests against real dependencies where a mock would hide the actual failure. Coverage percentage is a diagnostic, never a target.

  • Security is a design input

    Threat modelling during design rather than a scan before release. Dependencies pinned and audited, secrets never in source, least privilege by default, and an SBOM produced at build time so you know what you are actually running.

  • Documentation that stays true

    Documentation lives with the code and changes in the same pull request. Decision records are immutable — superseded rather than edited — so the history of the design remains readable.

  • Honest status reporting

    If something is late, blocked or turned out harder than estimated, you hear it in the next update, not at the deadline. Bad news early is a service; bad news late is a liability.

  • You own everything

    Source, infrastructure definitions, documentation and credentials are yours, in your repositories and your accounts, from the first commit. No proprietary framework you have to keep paying us to maintain.

Working together

Four ways to engage

Different problems want different commercial shapes. We will tell you which of these fits — including when the answer is the smallest one.

Architecture review

One to three weeks

A focused examination of an existing or proposed system.

We read the code, the diagrams and the incident history, interview the people who run it, and report on what will break first, what will not scale, and what should be done in what order. Fixed scope, fixed duration.

Right when
You have a system under strain and need an outside read before committing budget.

Design and build

Project-scoped

End-to-end delivery of a defined system.

The full five stages, from framing through hand-over. Scope and milestones agreed up front, with a review gate at each stage boundary where continuing, changing course or stopping are all legitimate outcomes.

Right when
You have a system to build and want one accountable engineering owner.

Embedded partner

Ongoing, monthly

A senior engineer inside your team on a recurring basis.

Architecture ownership, design review, mentoring and hands-on delivery alongside your engineers. Structured as reserved capacity per month rather than an open-ended timesheet.

Right when
You have a capable team that needs depth in a specific discipline.

Specialist intervention

Days to weeks

A hard, bounded problem that needs the right specialist now.

A latency regression nobody can explain, a device failing intermittently in the field, a network event with no root cause, a migration that has stalled. We diagnose, fix, and document what happened so it does not recur.

Right when
You have a specific problem and a deadline.

Commercials are agreed per engagement against defined scope. We do not publish rate cards, because a number without a scope is meaningless to both of us.

The first conversation is a scoping call, not a sales call. If we are not the right people for the work, we will say so — and where we can, point you at who is.
