About Konishi

Built from
first principles.

Konishi AB is a Swedish consulting company founded by Jens Nordmark, specialising in industrial and commercial software engineering. Available embedded within larger organisations as well as for independent project engagements.

The name comes from a virtual polity in Greg Egan's novel Diaspora — a place defined by constructed identity, mathematical rigour, and the freedom to build entirely new realities from scratch. Its protagonist, Yatima, is a citizen of Konishi created by algorithm rather than born — the name means orphan in Swahili, a nod to radical self-determination unconstrained by origin.

Registered in Sweden as an Aktiebolag (AB). Available for projects across Sweden and internationally.

your project.

Whether you have a fully scoped brief or an early-stage idea, I'm happy to have an initial conversation.

Note: Jens is currently taking assignments via C/O Codic AB rather than directly through Konishi.
