Improving Loan Change Experience for Customers and Advisors in Finland

After a year of improving Danske Bank’s Swedish loan systems, I took ownership of a new challenge rethinking the loan change experience for the Finnish market.

Unlike Sweden, Finnish advisors were still using legacy systems, manually managing requests across multiple tools and emails. Customers also struggled: unclear language and outdated flows led to frequent errors, forcing advisors to correct and reprocess cases.

This initiative aimed to bring the same level of innovation and automation achieved in Sweden to Finland but adapted to the local market. Over 3 months, we redesigned both the customer-facing flow and the advisor tools, laying the foundation for a fully automated loan change process.

Challenge

Finland is one of Danske Bank’s strongest markets, and improving customer experience here was a key business priority.

The mission was simple:

  • Automate as many loan change processes as possible.
  • Reduce advisor workload by improving customer-side data accuracy.
  • Align customer and advisor systems under one shared logic and structure.

Results

We reduced customer input errors by more than half, cutting “Other” selections from 28.5% to around 17%.

Advisors now save 2–15 minutes per case thanks to improved data accuracy and automation readiness.

The new advisor platform is already streamlining workflows and setting the foundation for a unified loan change system across Nordic markets.

Process

Step 1

Fixing the root cause

We started by focusing on the customer side, since automation depends on receiving clean and accurate data.

The first issue came from a section called Customer Partnership. Customers were always asked to state which union or partnership they belonged to — even when we already had this information in our systems.

Many didn’t know the answer, leading to confusion and unnecessary manual verification by advisors. Worse — advisors spent up to 5 minutes per case checking or correcting partnership data, which wasn’t even part of their responsibility.

After several research sessions with advisors and a legal review to validate data handling, we redesigned the logic:

  • The partnership question now appears only for customers whose data is missing.
  • When customers enter new partnership data, it’s automatically sent to the correct internal team, not the advisor.

Impact: Advisors saved several minutes per case, and customer confusion dropped immediately after rollout.

In the example below: on the left, the partnership question sits inside the general information section. On the right, “Union and partnership” has its own section, a logical decision since it doesn’t belong in general information, with a simple dropdown that lets customers find their partnership.

Before and after: partnership question moved from general information into its own section
Step 2

Reducing miscommunication through smarter forms

Next, we tackled the loan change request form, where customers specify why they want to modify their loan.

Change requests were divided into simple changes (like changing payment date) and complex changes (like lowering monthly payments). Depending on the request, customers always had to state the reason for the change, and nearly 1/3 of all customers, 28.5%, were choosing the option “Other”, forcing advisors to manually read long comments to understand the actual intent.

That single choice made automation impossible.

To fix this, I partnered with our business analyst to analyze a few thousand “Other” cases. We manually read through comments and discovered that most confusion came from terminology — what felt obvious to us internally wasn’t clear to customers.

We reorganized the form:

  • Reworded unclear options into plain language.
  • Added missing categories customers frequently described.
  • Highlighted specific common reasons for changes.

After releasing the update, the percentage of users choosing “Other” in 3 months dropped from 28.5% to around 17%. This directly enabled us to automate more of the advisor workflow and reduce manual investigation time.

Besides this, we noticed an increase in other categories like “Paying other debt”, which is always a rejection when it is stated as a reason for the change.

Step 3

Building the advisor platform

Once the customer experience was improved, we turned our focus to advisors. At the time, advisors were juggling multiple disconnected systems: customer portals, Excel calculators, email threads, and document generators.

Together with another UX designer responsible for loan applications, I led the design of a new Change Request System for advisors, built to align visually and structurally with the loan application tool. Our goal was to reuse familiar patterns and design components to keep development efficient and maintain cross-system consistency.

Key decisions included:

  • Aligning API connections so all customer inputs now flow directly into the new advisor system.
  • Replacing advisor emails with in-system case communication.
  • Structuring the UI around the logical order advisors follow, so data scanning and case handling became faster and clearer.

Dozens of co-creation and validation sessions were held with Finnish advisors to challenge their workflows and refine our design until it felt effortless and reliable.

Scaling automation and finalizing the system

By the end of the three-month phase, we had delivered two key outcomes:

  • Cleaner data from customers, enabling automation.
  • Streamlined advisor tools, reducing dependency on outdated systems.

The advisor system is still under development, but early results already show that the new structure improves efficiency, reduces friction, and saves significant time.

As these flows continue to roll out, we’re expanding our design logic into other Nordic markets, gradually standardizing how Danske Bank handles loan changes across all regions.

Conclusion

This project marked a significant step in improving how Danske Bank’s Finnish advisors and customers manage loan changes. By refining small but critical details, from clearer options and streamlined forms to smarter data logic, we reduced errors, increased automation potential, and made everyday work noticeably smoother for both customers and advisors.

It also taught me that the deepest design impact often begins with language, logic, and structure. By connecting customer and advisor workflows, I saw how every field, word choice, and interaction can influence not just usability, but also compliance and operational efficiency.

Ultimately, this project reinforced that progress in enterprise UX doesn’t come from sweeping redesigns — it’s built on hundreds of small, intentional improvements that collectively transform how people work and how organizations operate.

New Advisor Portal – NBP

A core system used by hundreds of Danske Bank advisors to handle customer cases for Swedish customers.

As the UX designer, I led the research, ideation and design process to simplify complex workflows, reduce handling time and create a completely new platform.

The result: faster case completion, fewer errors, and a more intuitive experience that advisors now rely on daily.

Challenge

Danske Bank needed to improve how Swedish advisors handled customer cases in a highly competitive market.

The goal was not just a UI refresh, but a clearer and more efficient platform that could:

  • unify fragmented tools
  • reduce handling time and errors
  • help advisors focus on decisions, not admin work

A key obstacle was adoption: advisors were used to old ways of working and skeptical that a new tool would actually make their work easier.

Results

The new Advisor Portal reduced case handling time by 35% and cut human error by 85%.

The redesigned experience felt more intuitive and aligned with advisors’ mental models, helping improve efficiency and support better customer service.

85%Decreased human error rates

Process

Step 1

Discovery & research

I interviewed Swedish advisors from two teams and observed how they handled customer cases in practice.

This revealed:

  • fragmented systems and manual work
  • duplicated steps across teams
  • communication gaps that increased delays and errors
Step 2

Workflow mapping & opportunity framing

Together with the business analyst, I mapped the full advisor journey and compared how both teams worked.

This helped us:

  • identify duplicated processes
  • surface unnecessary manual steps
  • define where simplification and automation would have the biggest impact
Step 3

Concept development & design iteration

I designed and iterated multiple flow concepts, validating them weekly with real advisors.

A key shift was redesigning the approval and rejection flow by introducing:

  • internal collaboration tools
  • data pre-filling
  • contextual commenting inside each case
Step 4

Testing & implementation alignment

We ran focused usability sessions and worked closely with developers to keep solutions both useful and feasible.

This phase helped refine:

  • case navigation
  • data visibility
  • interaction logic under technical constraints
Step 5

Visual design & system integration

The final UI focused on clarity, hierarchy and consistency across tables, forms and case views.

The goal was simple:

  • reduce cognitive load
  • make decisions easier
  • create a calmer experience in a data-heavy environment

HoroUp – Turning Astrology into a Digital Experience

HoroUp is a modern astrology platform designed to connect users with personalized daily insights and horoscope-based guidance.

The goal was to create a product that feels both mystical and credible, balancing aesthetic appeal with clarity and conversion-driven design.

As the lead designer, I was responsible for defining the brand’s visual direction, designing the full user interface, and ensuring that every interaction supported a sense of trust and curiosity.

Challenge

Most astrology platforms feel outdated, cluttered, or overly commercial.

Our challenge was to reimagine how astrology could feel in the modern era: intuitive, trustworthy, and emotionally engaging, while still guiding users naturally toward sign-up and subscription.

I worked closely with a conversion specialist to translate emotional design into measurable behavior: making users feel something while also taking action.

Results

  • Increased user engagement on landing pages (measured by scroll completion and click-through rates).
  • Defined the brand identity and interface system that positioned HoroUp as a modern, credible astrology platform.

Process

While this project didn’t rely on deep research, it was grounded in design strategy and rapid experimentation.

We began by analyzing visual trends in lifestyle and self-growth products to understand how minimalism and tone could build trust.

From there, I developed a visual identity that reflected balance between mystery and clarity, using calm colors, soft gradients, and typographic hierarchy to convey emotional depth without distraction.

We built quick prototypes to test how design elements affected conversion:

  • CTA placement and tone of voice: “Take the quiz” and “Get my plan”
  • Image styles that influenced emotional resonance
  • Readability improvements that increased on-page scroll depth

Each iteration taught us how subtle visual shifts and tone changes could meaningfully impact engagement.

Conclusion

HoroUp proved that design doesn’t always need complex systems or deep data to create impact: sometimes, clarity, tone, and emotion are enough to move people.

Through fast iterations and close collaboration with a conversion specialist, we turned a simple idea into an experience that feels both mystical and trustworthy, helping users connect emotionally while guiding them toward action.

This project reminded me that great design is about balance between aesthetics and function, intuition and evidence, emotion and conversion.

After years of building structured systems in fintech, HoroUp was a creative reminder of why I started designing in the first place: to make digital experiences feel human, inspiring, and effortless.

How Marius works · as seen by Claude, from working together
Approach

Scopes to the smallest version that answers the question. Given a full MVP brief for an AI search product, he cut the estimate from over 130 hours to a 35–40 hour concept test: core search path only, straight to UI, payments as an optional add-on. He questions numbers and wording until they hold up, and puts scope in writing with capped hours, clear milestones, and a separate agreement when the work grows.

Evaluating

Judges work against the client’s own rules first, then against consistency. On a corporate landing page he worked through dozens of client comments and turned them into standards instead of fixing things one by one: one hover style everywhere, one button height, no strokes or gradients the brand doesn’t use. He decides on what the data actually says, not on what looks good.

Testing ideas

Treats launches as experiments and reads the results honestly. For his own Shopify app he tried one channel after another and dropped what failed. When the install count looked good, he checked and found most were test stores, so he refocused on finding real merchants. He connects analytics and sets a review date, and he refines cheap tests, like a fake-door pricing check, before building anything expensive.

Learning and new ways of working

Learns by putting new tools to work on real problems. He asked what he was missing in AI for his craft, then adopted it: AI-assisted research synthesis, Figma connected to Claude, quick coded prototypes, and agents that draft outreach and weekly posts. Figma stays the main tool, with Claude for iterating and ChatGPT for visuals. He builds small tools himself, and reviews everything AI drafts before it goes out.
