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.

UX/UI Design | AI-assisted Development | Content Integration | Deployment
Challenge
Customers needed easy access to current menus, events and reservation requests, while the café needed a practical way to keep content up to date.
Contribution
Designed and built the responsive website using AI-assisted development, including reservation requests, form validation, server-side emails and content updates through Google Sheets.
Outcome
A live website with an integrated reservation request flow and editable content, allowing the café to update menus and events without changing the source code.
I created a cohesive visual and digital experience for VinCaffé, a neighbourhood café in Prague.
The project extended beyond the website and included the development of the café’s visual identity and its application across both digital and physical touchpoints — from menus, business cards and illustrations to the website and online reservation experience.
I designed the visual system and customer-facing materials, then implemented the final responsive website and supporting functionality.

VinCaffé needed more than a standalone website. The goal was to create a consistent visual identity that could work across the café’s physical and digital communication.
Customers interact with the brand through printed menus, in-store materials, online content and the website, so these touchpoints needed to feel connected while still remaining practical and easy to maintain.
For the website itself, visitors needed quick access to frequently changing information such as weekly menus, weekend brunch, events, opening hours and reservations.
I developed the visual direction of the brand and translated it across both print and digital applications.
This included designing menus, business cards, illustrations and supporting graphic assets, as well as defining typography, colours, visual styling and reusable brand elements.
I then applied the same visual language to the website, designing the responsive interface and implementing it in HTML, CSS and JavaScript.
I also developed the reservation flow, including form validation, loading and success states, reCAPTCHA protection and server-side email handling with PHP and PHPMailer.
Frequently updated website content such as weekly menus, weekend brunch and events is connected to Google Sheets, allowing the café to manage content without changing the source code.
The visual identity was designed to reflect the warm, informal and personal character of the café.
Rather than treating each output as a separate design, I created a shared visual language that could be reused across the brand.
This included:
The same visual principles are therefore visible across both the physical café experience and its digital presence.
The result is a consistent brand experience across print, digital communication and the website.
VinCaffé now has a reusable visual system that can support everyday communication as well as a responsive production website where customers can browse current menus, discover events and send reservation requests.
Dynamic content can be managed independently through Google Sheets, while the website and reservation system require minimal ongoing technical maintenance.
