System development / 02Yellion / Karlstad

Systems built around the business.

We develop web-based systems and custom applications for needs that off-the-shelf software cannot quite solve — with the business, its users and long-term maintenance in the same picture.

Starting point

When the tool should follow the work — not the other way around.

Custom system development makes sense when the way you work is central to the business, several roles need to come together or existing solutions have become an obstacle.

01

Off-the-shelf software is not enough

Important steps happen outside the system — in spreadsheets, email threads or specialised routines that only a few people know.

02

A legacy system is holding you back

The solution is business-critical but difficult to change, expensive to maintain or built on technology that limits the next step.

03

Information has no clear home

Customers, members or employees need one portal where the right data, cases and functions are readily available.

What the service includes

Web development for more than a website.

We build web-based software that people use to get work done: from focused internal tools to business systems and SaaS solutions with many users.

01

Web applications & portals

Customer portals, member platforms and self-service solutions with clear roles, secure sign-in and carefully designed flows.

02

Business & administrative systems

Custom systems for processes, cases and information that are unique or especially important to the organisation.

03

SaaS & digital services

Web-based products with accounts, subscriptions, permissions, data and the technical foundation required to run a service over time.

04

Modernisation & continuous development

Existing systems can be improved step by step. We map dependencies, reduce risk and keep the business running through the change.

In practice

System development with a clear job to do.

Typical engagement / 01

A business system has outgrown its original solution.

Core workflows need to be modernised without bringing the organisation to a halt. We break the change down and migrate one function at a time.

Typical engagement / 02

Customers need to manage their own cases.

A customer portal brings information, documents, status and recurring tasks together in one clear web application.

Typical engagement / 03

Internal administration takes too many steps.

A custom tool brings rules and workflows together, reduces duplicate work and makes the next action clear.

How we work

Explore. Build. Improve.

We start close to the problem and build in stages. That creates frequent feedback, short decision paths and room to adjust before the wrong things become expensive.

  1. 1

    Explore

    We understand processes, roles, data and technical dependencies, then define a sensible first scope.

  2. 2

    Build

    The system is developed in working increments with continuous quality assurance, security work and user feedback.

  3. 3

    Improve

    After launch, we follow performance, usage and emerging needs, then improve where it creates the most value.

Technology when it adds value

A sustainable technical foundation.

Good system development is about more than code. We consider security, accessibility, performance, data models, integrations and how the solution will be maintained.
