Infrastructure and Security

Complex digital products for industries that can't afford to get it wrong.

Keplyr builds the systems that sit behind regulated, high-stakes businesses: the APIs, the secure portals, the calculators, the platforms your compliance team has to sign off on. We also build the front end people actually use, whether that's the interface on top of one of those systems or a standalone site that needs to launch fast and be easy to run. We work where the margin for error is zero and the auditors are real. In superannuation, financial services, healthcare, and energy, a broken integration or a leaked record isn't a bug ticket. It's a regulator's attention and a headline you don't want.

We build for that reality from the first line of code, not as a clean-up at the end.

Front-end engineering

A good design is only as good as the build behind it. We hold front-end engineering to the same bar as everything else we ship: performance that doesn't degrade under real traffic, accessibility that meets the mark in sectors where it's not optional, and design-system fidelity so what ships matches what was designed.

CMS and content platforms

A site is only useful if you can run it. We build on content platforms that let your team make changes without coming back to us for every update. We're platform agnostic and will build on whatever CMS matches your objectives and integrates best with your systems, processes and technology stack. We match the platform to the job, not the other way around.

APIs and systems

We build APIs and integration layers that connect messy, legacy environments to modern front ends. Projection engines, member data, third-party feeds, authentication flows. Clean contracts, proper documentation, and architecture that holds up when volume and scrutiny both go up. You get systems other teams can build on, not a black box only we understand.

Built for regulated industries

Compliance isn't a constraint we bolt on at the end. It shapes the build from day one. RG276, actuarial input, and sector-specific obligations are part of how we scope, not a surprise in UAT. When your product has to stand up to a regulator, an auditor, or a board, it's built to.

Security and data residency as defaults

Behind-the-PIN number crunching, authenticated environments, and PII handled the way it has to be. We design for data residency, access control, and secure-by-default architecture, because in these industries a breach isn't a headline problem, it's an existential one. Security isn't a feature we upsell. It's the baseline.

DevOps and delivery you can audit

The build is only half of it. We set up the pipelines, environments, and controls that move code from commit to production without drama: automated testing, infrastructure as code, staged deployments, and change management that leaves a paper trail. In regulated environments you have to prove how something shipped, not just that it works, so we build delivery that stands up to review and keeps running long after launch.

Why work with us

Most agencies can build you a website. Far fewer can build a system that survives contact with an actuary, a compliance officer, and a security review. We've done it for the kind of organisations where that scrutiny is the norm, not the exception. We know the terrain, the terminology, and the stakes, so you spend less time explaining your world and more time shipping in it.
