KaRZMa Code works in two complementary directions, and the first is the one that defines it.
Products are software we own. We choose the problem, design the solution, publish it under our own name and keep it maintained. LinkNest — an offline-first app for saving and organising links, available for Android and Windows — is the first of them, and the product this entire site was built and tested against.
Services are software we build for someone else: mobile, web, desktop and custom development, shaped around a requirement that already exists rather than one we chose.
The two reinforce each other. Products are evidence — anyone can read what we claim about quality and then go and use something we built to that standard. Services are how the same capability reaches problems we would never have found on our own.
