Janus Jektvik · Founder
You work directly with Janus, a software consultant whose experience spans backend, frontend, mobile, cloud, and regulated environments.
I stay involved from product decisions through implementation and operation. The architecture should serve the work, and the work should stay understandable. Additional capacity comes in when the project calls for it.
Previous roles at Dawn Health and Netcompany span health software, enterprise systems, and banking. That experience informs how I approach product delivery today.

How we work
Clarify the user need, constraints, and next useful release. Whether it is a web product, mobile app, or AI workflow, the scope starts with what it must accomplish.
Turn decisions into working software you can review. Validate external data, make failures visible, and use senior review alongside AI-assisted development.
Bring deployment, monitoring, and recovery into the delivery plan. Reproducible environments and clear ownership make the product easier to operate and change.
Bring an early idea, an existing product, or a brief that is ready to deliver. We can start by working out what the next useful step looks like.
