GRAFOSTAR

Engineering for the iOS platform, built to outlast its first release.

Architecture Performance Longevity
Mandate

Software that holds its shape

We design and develop modern digital software for the iOS platform and the technologies around it. Scale is decided in the architecture, not discovered later — the structure a system ships with is the structure it can grow into.

Speed alone is not a finished result. A build that renders fast but behaves unpredictably has not met the requirement, and neither has one that is stable but awkward in the hand.

Method

Three commitments

ArchitectureBoundaries are drawn before the first screen is. Domain logic stays independent of presentation and of the frameworks beneath it, so a layer can be replaced without the rest of the system noticing.
PerformanceMeasured, never assumed. Cold start, scroll smoothness, memory footprint and energy draw carry numbers, and regressions are caught against a baseline rather than a feeling.
DesignThe interface is the whole product for the person holding the device. Interaction, motion, typography and accessibility are designed with the system, not applied to it afterwards.
Platform constraints

Numbers handed to you first

8.33ms

Frame budget at 120 Hz

Every layout pass, decode and animation tick on the main thread shares one frame. Exceed it once and the drop is visible in the hand.

16.67ms

Frame budget at 60 Hz

The floor every supported device class still has to meet — which is why work is profiled on the slowest hardware in scope, never the fastest.

8pt

Base spacing unit

One rhythm the layout grid resolves to, so spacing stays predictable across screen sizes, dynamic type settings and safe-area insets.

3× raster

Scale factors, one source

Interface assets are authored once and have to hold at every raster density the platform asks for — no redrawing, no visible drift between them.

12months

Platform revision cycle

A major release lands every year. Systems are built so keeping pace stays routine maintenance instead of becoming a rewrite.

Durability

Maintainability pays longest

Code is written for the engineer who inherits it, with naming and structure that survive the context in which they were first obvious. Every change passes review, where correctness, performance impact and architectural fit are weighed together rather than in sequence.

Structural debt is repaid on a cadence, so the cost of a change stays roughly constant over the life of the system instead of quietly compounding.

The second year of a system is the honest test of the first.

Advance

The process is revised too

Engineering standards move, and a team that does not move with them accumulates a quiet kind of debt. Internal workflows, review practice and delivery pipelines are examined on a regular cadence and changed where the evidence supports it.

New technologies are explored before they are needed, judged against real constraints rather than novelty, and adopted only once they measurably improve reliability, performance, or the clarity of the systems built with them.

Future-ready is a property of systems, not a claim about the roadmap.
