Apps. Systems.Applied AI.

We work across applications, distributed systems, and applied AI. Our scope runs from architecture through implementation and production, whether we’re building a product or taking on a critical part of one.

ServicesNew builds & existing software

From the app
to the system.

Some projects begin with an idea. Others begin with software that needs to do more. We can take on the full build or a defined part of the work.

Product engineering

We design and build native mobile apps and web applications, including their backend services. We can develop a product from its first prototype, add functionality to an existing application, or take over ongoing development. The work covers interface design through implementation and release.See our work on Below

Systems engineering

We build backend services, data pipelines, and integrations with external platforms. We also work on systems already in production: migrating data, replacing legacy components, and improving performance and monitoring. We take on the architecture, implementation, and production rollout.

Applied AI

We help teams decide where AI belongs, prototype the approach, and build it into a product or internal workflow. For large language models (LLMs) and agents, the work includes context and tool interfaces, structured outputs, and durable execution. Tool permissions and approval gates belong in the surrounding software, not solely in a prompt. Latency, cost, and failure recovery shape the architecture.

AI evaluation

We build versioned datasets and repeatable evaluation harnesses around task-specific criteria. Deterministic checks cover behavior with a clear expected result; model-based grading applies an explicit rubric. We inspect failures at the case level and compare repeated runs against a baseline, because an aggregate score can hide regressions. Production traces feed back into the evaluation set.

Websites

Websites that explain a business’s services and give customers a clear way to get in touch. We handle design, development, and ongoing changes.

Built & maintained by RustpointOur product

Below.

An app of our own.

Below is our dive logging and discovery app. It connects to compatible dive computers over Bluetooth and brings recorded dives into a native application for review.

Our work spans product design, device integration, dive-data processing, and the supporting services. We build and maintain the product after launch.

Working together

A defined scope.
Hands-on delivery.

We start with the requirements, existing architecture, and operational constraints. We agree on the deliverables and how the work will be assessed, then take responsibility for the implementation.

The engagement can cover a whole product or one part of a system, with continued development and support after release.
