Hi, I’m Karo — a UI Engineer. I believe in the limitless potential of design to simplify complex problems. I work at the intersection of design and code, creating intuitive, scalable and future-proof interfaces, design systems, and tools that make life easier for both users and developers.

Arqiva

UI Engineer

2023 - presence

I led the initial redesign of a complex live media exchange platform, improving usability and consistency across the product. I also helped to build a custom React Component Library that is now used across all digital products, enabling scalability and design alignment. Alongside this, I mentored and onboarded developers and designers at different levels, strengthening collaboration within the team.

The University of Edinburgh

Web Developer

2021 - 2022

I mentored interns and supported their transition into professional workflows. I helped designers shift from Sketch to Figma, making collaboration and handoff more efficient. I also assisted with the development of a content migration strategy from Drupal 7 to Drupal 9, which enabled a smoother transition of university materials into the new system.

WOOs

Product Designer (Contract)

2019 - 2020

I modernised the company’s website to improve brand presence and user engagement, and I designed the UI for an aircraft servicing app, turning complex workflows into a more intuitive digital experience.

A big story about me

I still remember when I became fascinated with web graphics. I was 11 years old, playing with Windows XP Paint on the only computer in our household. I’d spend hours drawing pixel-perfect shapes, carefully counting the exact number of pixels and their positions. At the time, they were just tiny squares to me — but soon I discovered bits and bytes, binary and hexadecimal numbers, digital colour, and Imagine, a Slovak programming language. That’s when I realised there was more than just arranging pixels — there was a whole world of logic and design working together.

That early obsession with detail and structure naturally grew into a career where I now work as a UI Engineer, blending design and engineering. Along the way, I’ve explored everything from front-end development to product design, but I’ve always gravitated back to creating interfaces that feel intuitive and human. In fact, at my current company I’ve become known as “the person who designs things,” often being invited into design conversations beyond my formal role.

Today, I thrive at the intersection of design and engineering — turning complex problems into simple, scalable solutions. I especially love working on design systems: at Arqiva, I led the design of a company-wide component library that streamlined workflows for both designers and developers, ensuring consistency at scale. I also enjoy mentoring, collaboration, and exploring new technologies, including AI, to keep pushing my craft forward.

Looking ahead, I’m driven to deepen my expertise as a design engineer and take on greater responsibility. I want to grow into more senior roles where I can shape products end-to-end, influence design strategy, and empower teams through thoughtful systems and collaboration. Ultimately, my goal is to keep learning, keep challenging myself, and help create products that not only work seamlessly but also genuinely improve people’s lives.
