AI Damage Detection
A fleet audit platform designed to support banks and leasing companies managing vehicle inspections across multiple locations.
The platform connects field auditors, coordinators and financial stakeholders by combining vehicle data, inspection results, AI-supported assessments and audit history into one digital workflow.
The platform needed to support multiple user groups with different goals and workflows.
Field auditors required a simple way to inspect vehicles, capture information and document damages on-site. Coordinators needed to manage assignments and monitor audit progress, while banks required a clear overview of vehicle condition, history and status.
As the UX/UI Designer, I focused on designing the main user flows, information structure and interface concepts across the platform.
My work included:
I collaborated closely with the Product Owner to understand business requirements, structure complex information and translate processes into user-friendly solutions for development.
I started by understanding the complete audit lifecycle and mapping how information moved between different users and stages of the process.
From there, I created user flows and structured the information hierarchy to ensure that each user could quickly access the information relevant to their role.
The designs were iterated through discussions with the Product Owner and refined into prototypes and implementation-ready interfaces for the development team.
Prioritizing information hierarchy
The platform contained many different data points, from vehicle status and inspection results to historical audits and damage information.
I focused on presenting the most important information first and creating clear visual relationships between overview screens and detailed views.
Designing for multiple roles
Instead of creating one generic experience, the interface was structured around the different needs of auditors, coordinators and financial stakeholders.
Each role required different levels of detail, actions and information visibility.
The project established a structured digital workflow connecting vehicle inspections, audit management and fleet visibility within one platform.
The designed flows and interfaces provided a foundation for development and supported collaboration between business stakeholders, product teams and engineers.

Service & Customer Lifecycle
An enterprise SaaS platform supporting automotive dealerships throughout the customer lifecycle — from initial lead analysis and customer contact to vehicle offers, contracts, delivery and after-sales processes.
The platform connected sales activities, customer information and operational workflows into one integrated environment used by dealership teams.
The platform covered multiple stages of the customer journey and supported different dealership roles with different goals and responsibilities.
Sales teams needed efficient ways to manage leads and customer interactions, while managers required structured overviews and visibility into ongoing activities.
As a UX/UI Designer, I focused on improving existing workflows and designing new product capabilities based on business needs, user feedback and process analysis.
My work included:
I collaborated closely with the Product Owner to understand business requirements, structure complex information and translate processes into user-friendly solutions for development.
I started by understanding how users worked with the existing platform and where processes created unnecessary complexity.
By analyzing workflows and discussing requirements with stakeholders, I identified opportunities for improvement and translated them into clearer user flows, interface concepts and functional designs.
For new features, I designed both customer-facing experiences and internal workflows, ensuring that different user roles could complete their tasks efficiently.
Simplifying complex business processes
The platform supported multiple connected processes across the customer lifecycle, from lead analysis and customer communication to offers, contracts and delivery.
I focused on understanding the real working process behind each feature and redesigning flows to make tasks clearer, faster and more intuitive for users.
Designing for multiple roles
New features often affected both customer-facing experiences and internal teams managing the process.
I considered both perspectives when designing solutions — ensuring that customer interactions were simple while internal workflows remained efficient and manageable.
Created more user-friendly workflows and clearer product experiences across different stages of the customer lifecycle.
The improvements provided a stronger foundation for further product evolution, with better alignment between user needs, business processes and technical implementation.

Tutor
Martin was an exceptional student at CareerFoundry. During his UX design course, he mastered a complete project from scratch. His solutions for different kinds of problems are both functional and appealing. His design language is laying with the trends. He was able to work out nice reduced simple user flows. He is a fast learner and picks up the feedback to grow. I'm curious to see where he'll be in a few years...
