    Ottex AI

    AI is changing how people interact with their computers. I design the interfaces that make it feel easy.

    Ottex is an AI-powered voice-to-text app for macOS. I designed the product interface and the website. As an active AI user myself, it was important to me to create a neutral, simple interface that feels intuitive — since this is essentially a tool that simplifies your life, using it should be just as simple. No unnecessary complexity, no overdesigned screens. Just a neutral interface that feels obvious from the first launch.

    Freelance | Self-Employed

    Every project started with someone else’s vision - and I loved turning it into something real and usable.

    As a freelance UI/UX designer, I worked on a range of projects - from landing pages and websites to full mobile apps. Each client brought a different challenge, and that variety taught me to adapt fast, ask the right questions, and deliver designs that actually solved problems. The best part was seeing how a well-thought-out interface could completely change the way people interacted with a product.

    3Jane Technologies

    I designed systems, not just screens - and I genuinely believe that’s where the most interesting design work happens.
    At 3Jane, I contributed to creating a design system that connected design directly with development. I learned how to structure themes, components, and tokens so they work consistently across products. The system’s automation made updates over 3 times faster — and working on it taught me how design decisions impact development speed.

    Loqus AI

    There’s nothing quite like designing something that didn’t exist yesterday — and watching people use it today.

    At Loqus, I built a product from scratch into a working solution. This role was a great opportunity to enhance my design skills, allowing me to make thoughtful decisions and support them confidently. Working alongside a strong team, we moved fast through open collaboration and honest discussion.

    steady-parent.com

    Designing for parents made me think about clarity differently - every screen had to feel effortless.

    I created the Steady Parent website from the ground up - a platform offering a practical course for parents who want to build essential thinking skills in their kids. I was responsible for the entire design: site structure, user flows, and visual design. The goal was to make an educational product feel warm, trustworthy, and easy to navigate.

    When I started working on Steady Parent, I realized I was designing the kind of tool my own parents would have loved to have. That connection made me care about every detail and how a client can still find exactly what they need in two taps.
