Overview

The mortgage process is often complex, bureaucratic, and emotionally taxing. My role was to reshape the digital experience. Transforming a dead-end, rigid system into a seamless, user-friendly journey. By streamlining processes, reducing friction, and aligning the flow with the bank’s positioning as the most user-friendly bank, we empowered users to navigate their mortgage applications independently. The result: a faster, more intuitive experience that left users feeling confident and accomplished, without needing a banker's assistance.

Key Outcomes

  • 90% increase in process completions compared to the previous application

  • 27% higher retention at the business agreement phase (initial mortgage approval)

  • 50% increase in retention at the principle approval phase (advanced mortgage approval)

  • Reduced the number of unnecessary financial questions, minimizing friction and shortening the process

Overview

The digital loan process was redesigned to align with the bank’s existing design language.

The updated flow balanced the bank’s goal of promoting fixed-interest loans with user needs, ensuring a transparent and user-friendly borrowing experience.

Key Outcomes

  • 26% total conversion rate

  • 27% increase in customers choosing a fixed-interest loan digitally compared to in-branch customers

  • Since launch, over 420 loans approved daily with no human intervention, fully digitalized, averaging 50,000 (€12,000) per loan

Swish • Gift Ordering System for Organizations

Designing a B2B SaaS Product from Scratch

Responsive Web Design

UX Designer, Researcher

2023

2024

UX designer, UI Designer, Product Manager

Overview

Swish is a SaaS-based gift ordering system designed to simplify and streamline the process of purchasing and distributing gifts for organizations. I designed a self-service experience covering the entire journey, from the bidding process to final checkout, enabling businesses to independently manage corporate gifting in a clear, guided flow. In the second phase, I created a back-office system for the client’s sales and operations teams to manage bids and orders internally. These processes, previously handled manually, are now fully digitized, giving organizations greater autonomy while keeping internal workflows efficient and structured.

Key Outcomes

  • Created a fully responsive, scalable self-service platform for organizational gifting

  • Digitized manual sales and operations workflows into a structured internal system

  • Improved clarity and independence in the ordering process for both clients and admins
