Services
Three disciplines: native Android applications, cloud and API infrastructure, and Google Ads management. Each can be engaged on its own. Taken together they close the gap between the system that produces a number and the campaign that is optimised against it.
Service lines
Campaign execution, measurement and transparent agency oversight for businesses advertising on Google Ads.
Native Android engineering built for reliability on real devices, not only in an emulator.
Backend services and infrastructure that stay predictable under production load.
Where the disciplines meet
Advertising failures are rarely advertising failures. They are usually an event that never fired, a value that was wrong, or a backend that reported something different from what the campaign was optimising toward. These are the three places that happens.
Mobile × Advertising
An app campaign optimises toward events the application emits. If the event fires on the wrong screen, fires twice, or carries a value that does not represent revenue, the bidding strategy learns the wrong thing — and the campaign report will still look clean.
We define the event schema in the application, verify it in Firebase, and only then let the campaign optimise against it.
Backend × Advertising
Value-based bidding needs a value the backend can actually stand behind: a confirmed order rather than an intent, net rather than gross, deduplicated across retries. That number comes from server-side logic, not from a tag.
We build the API and the reconciliation that produce the value, then feed it to the platform through the appropriate import path.
Mobile × Backend
Applications run on constrained devices with intermittent connectivity and aggressive process termination. Whether an event survives a dropped connection or a background kill is decided by the sync design, not by the analytics SDK.
Queueing, retry, idempotency and offline behaviour are designed together across the app and the API rather than assumed on either side.
Engagement shapes
The shape is agreed in the written scope. Commercial terms are set per engagement; the categories below describe structure, not price.
A
A bounded audit of an existing application, backend or advertising account, delivered as a written assessment. Deliberately separable from any implementation that follows.
B
A defined build with agreed deliverables and milestones — an application, a backend service, a migration or an account rebuild.
C
Continuous work with a review cadence: campaign management, application maintenance and release cycles, or infrastructure operation.
D
Technical or measurement advisory alongside a client's own team, where implementation stays in-house and we review architecture and instrumentation.
Included in every engagement
A written scope before work begins; a documented measurement definition; access limited to what the scope requires; a record of changes made; and commercial documentation that keeps platform media cost, agency service fees, development charges and third-party costs separate. See the billing policy for how those categories are invoiced.
Before you engage
If we will hold access to your advertising account, these four documents describe exactly what that means.
Questions
Yes. Google Ads management, mobile engineering and cloud engineering are separate engagements and are frequently taken individually. Combining them removes handover points in measurement, but it is not a condition of working together.
Yes. Taking over an existing codebase or account starts with an audit: what exists, what is instrumented, what is undocumented and what carries risk. The audit output is a written assessment, and it is deliberately separable from any implementation work that follows.
Fee structure is agreed in writing before work begins and depends on the shape of the engagement. What is constant is the separation: platform media cost, agency service fees, development charges and third-party infrastructure costs are always identified as different things. Full detail is on the billing policy page.
We do not offer brand or creative strategy as a standalone service, social media management, SEO retainers, or advertising on platforms outside our stated capability. We also do not guarantee advertising performance, app store approval or account reinstatement, because those outcomes are decided by the platforms.
