I HELP YOU MAKE THE RIGHT DECISIONS

An app that just “works” versus an app that actually succeeds.

The difference isn’t one feature.
It’s a hundred small decisions — and a few big ones.

WHAT MOST PEOPLE BUILDWHAT I CAN HELP WITH
01An app that simply works

Creating a user journey that makes sense

The steps it takes to make the user experience feel just right.

02An app that doesn’t make money

Monetisation — strategies that generate revenue

Making money from an app is entirely possible, but the business model and monetisation strategies need to be spot on.

03An app that doesn’t stand out

Standing out — in both design and execution

Vibe coding has brought a flood of mediocre apps and systems. You need to stand out from the crowd, and I know how to help you do it.

ARCHITECTURE BUILT FOR THE REAL WORLD

From your very first user —
to large-scale growth.

Selected projects I’ve been involved in. Different challenges. The same focus on the product, the user and solving problems.

STARTUP GROWTH · MAPS · MACHINE LEARNING

FiskHer

I helped build FiskHer’s technical platform and apps. Advanced maps, machine learning and data visualisation — in a product that grew from 0 to 300,000 users in three months and went on to pass one million.

ENTERPRISE · ONBOARDING

Kongsberg

An app that helped thousands of new employees find their way into Kongsberg’s organisation and culture. Described as the best-executed onboarding programme in Norwegian industrial history. Complex needs turned into a simple user experience.

DIGITALISATION · REAL-TIME DATA

Lerøy — Din Havn

A pilot project to improve logistics at fish reception facilities. Apps for fishing vessels and staff, administration and real-time data powered by Firebase.

Firebase · iOS

Experience across industries.

THE RIGHT DECISIONS AT THE RIGHT TIME

The most important decisions
often come before the first line of code.

AI makes building faster.
I help you put that speed to good use.
Strategy stays with the product throughout its journey, including after launch.

Strategy that gives you direction
01

Find the core

Who will use the app? Which problem matters enough to make them actually use it?

02

Prioritise deliberately

We choose what creates value in version one. Everything else has to earn its place.

03

Find your first users

A practical plan for your audience, distribution and a first experience that helps people move forward.

04

Learn. Improve. Scale.

We look at real usage, find the friction and prioritise what will make the next version even better.

THE PERSON BEHIND APPDEV

Hi, I’m Christian.

I’ve worked with digital experiences since 2005, helping shape new solutions as the world went digital. I was among the world’s first app developers and have been building apps since 2009.
In 2010, I founded Adept Mobile AS. Since then, I’ve combined design, development and technology leadership, with a focus on creating great mobile user experiences.

I work just as well with founders exploring their first idea as with established teams in large corporations. Working with me gives you someone who can discuss the business model, help set priorities and actually build the solution — both the backend and the frontend.

I focus as much on why we build something as on how we build it.

Away from the screen, mountains, the sea, fishing and hunting are how I recharge.

A FEW GOOD QUESTIONS

A few quick questions

Can you help with an app I built using AI?

Absolutely. I can review the project, identify what needs to be done and help you move forward. That might mean fixing bugs, improving architecture or user experience, or planning a launch. We build on what works.

Do you work with both founders and large businesses?

Yes. My experience includes startups such as FiskHer and projects for Kongsberg, Lerøy, HeltHjem, Telenor, Salmar and Oslo Børs, among others. We adapt the collaboration to your needs: a focused review, a project or a role within your team.

Do I need a finished specification?

No. An idea, a challenge or an existing app is enough to start a conversation. I can help clarify needs, prioritise scope and choose a sensible first step.

What does it cost to work with you?

That depends on the scope, your starting point and what you want to achieve. After an initial conversation, we agree on delivery, pricing and how to work together before work begins.

Can we work together internationally?

Yes. I work in Norwegian and English and can collaborate with teams internationally. We agree on a working arrangement that fits the project, team and time zone.

IT STARTS WITH A CONVERSATION

What’s on
your mind?

An idea to explore. An app to improve. Or a project that needs a new direction. Tell me a little about it and we’ll find a sensible next step.
