What kind of products do you work on?

Complex, data-heavy products: clinical and health platforms, dashboards and data visualisation, and design-led websites with creative front-end. If it combines real complexity with craft, it's a fit.

How do engagements work?

Three shapes: end-to-end product builds, fractional product engineering leadership, or technical advisory at founder and board level. UK-based, remote-first, working across UK, EU and US time zones.

Do you work with health and metabolic data?

Yes — it's a core domain. I've spent years building clinical dashboards, metabolic health platforms and HIPAA-compliant products: continuous glucose data, validated clinical instruments, and the confidentiality and regulatory boundaries that come with them.

Can you take over a prototype or vibe-coded app?

Yes. I take ownership of what exists, judge what's worth keeping, and turn the rest into a scalable product you independently own — no rebuild trap, no dependency on me to keep the lights on.

What does AI-native delivery actually mean?

I've been building with AI-assisted software practices since 2023, across numerous AI products. My delivery pipeline is built around it — codebases structured so AI agents work in them safely, refined over years of production builds. I ship solid products with it, and I show teams how to run the same setup themselves.

Is Kiah Digital an agency?

No. You work directly with me, Kiah Hewitt — an independent product engineer and technical partner. When a project needs more hands I bring in trusted specialists, and I stay accountable for the result.
