Software engineering for systems, platforms & web.

An independent Danish software company. Fridthjof Labs designs and builds production software — backend systems and cloud platforms, web applications, customer portals and company websites — and takes it from architecture through to running.

01Practice

Small enough to do the work, deliberate enough to keep it running.

Fridthjof Labs is an independent software company offering hands-on consulting and implementation. That covers a distributed backend on a cloud provider, an internal platform, a customer portal or a company website — the common denominator is software engineering, not one technology category.

Architecture, implementation, infrastructure, deployment and operation can all be part of an engagement, or only the parts that are missing. Work is scoped tightly and delivered as working software with the reasoning recorded alongside it. A handover is a system somebody else can run, not a slide deck.

02Capabilities

What Fridthjof Labs is hired for.

Software consulting

Hands-on engagements: working out what should be built, then building it. Reviews, second opinions and scoping for teams that already have a direction.

Systems & backend engineering

APIs, services and long-lived backends, designed around the operational reality they have to survive in rather than the demo. Data models, integrations and the boundaries between them made explicit.

Cloud & platform engineering

Infrastructure as code, edge and container runtimes, DNS, identity and secrets — with build, release and deployment paths a team can run without help.

Web applications & websites

Company and product sites, customer portals, internal and admin applications, and the web platforms behind them: fast, accessible, and maintained as production software rather than a campaign.

Software architecture

Decisions written down with their trade-offs, so a system stays changeable after the first release.

Developer tooling

Command-line tools, automation and internal services that remove repeated manual work and make the repository the source of truth.

Applied AI

Models put to work inside real systems — retrieval, assistance and automation — scoped so the output is reviewable and the system stays predictable.

03Work

Selected work.

Dykkerværkstedet

In production

Public website, customer portal and internal admin application for a Danish diving-equipment service workshop.

Three applications on one shared domain model and data layer: a public website for customers finding the workshop, a portal where they follow their own equipment through servicing, and an internal application the workshop runs the work from. Deployed on Cloudflare Workers with Firebase persistence and infrastructure managed as code, with review, deployment and security checks automated in the repository.

04About

About the company.

Fridthjof Labs is an independent software engineering company based in Denmark, established in 2026 as a sole proprietorship. Its registered activity is computer programming. It works with Danish and international clients, in Danish and English.

Capacity is deliberately limited to a small number of engagements at a time. Everything named on this page is work that exists — no placeholder clients, no borrowed logos and no claims that have not been built.

05Contact

Start with the problem.

Fridthjof Labs is available for hire. Write if you need a software system built, a web application or a website, consulting on an architecture or a codebase, platform and cloud work, or an engineer to collaborate with on something technical.

Enquiries in Danish or English. A short description of what you are building and what is in the way is enough to start.
