I build things that feel human

Aug 2023 – Present

Translator (English to Slovak)

RWS Self-Employed

💡 How it started: I fell into translation by accident, and immediately found myself in it. I have been translating ever since.

📌 What I do:

  • Localized UI and help content with product tone & terminology integrity.
  • Built a personal QA checklist for consistency across long projects.
  • Coordinated edge cases (brand terms, accessibility strings, pluralization).
Toolkit:
CAT Tools Product Style Guides UX Wording

✨ What I’ve learned: Language is UX. The right words guide people as much as design does.

Jun 2024 – Jul 2025

UX/UI Designer

UXtweak Self-Employed

💡 How it started: I wanted to design experiences that make research tools effortless to use. UXtweak gave me the chance to create interfaces where complexity feels simple.

📌 What I do:

  • Shaped and expanded the company’s design system (tokens, components, accessibility).

  • Designed new features and refined existing flows for clarity, usability, and visual consistency.

  • Conducted UI reviews and collaborated with product teams to turn research insights into intuitive designs.

  • Crafted marketing visuals and product pages to communicate UXtweak’s value with impact.

Toolkit:
Figma Design Systems Accessibility UI Reviews

✨ What I’ve learned: Design is not decoration. Every pixel is a decision that helps (or hinders) users in their journey.

Feb 2025 – Present

Frontend Developer

UXtweak Self-Employed

💡 How it started: I stepped into development to support the product team with creating and maintaining our WordPress ecosystem.

📌 What I do:

  • Develop and maintain custom WordPress features for UXtweak’s multisite setup.

  • Create and fine-tune Elementor widgets to align with the design system.

  • Ensure clean, maintainable PHP code integrated with modern workflows.

  • Collaborate with marketers and developers to bring marketing and product pages to life.

Toolkit:
Vue.js PHP WordPress TypeScript SCSS

✨ What I’ve learned: Development is design in another language. Code choices affect usability just as much as layouts do.

Product Design Lead

UXtweak Self-Employed

💡 How it started: My role naturally grew from designing individual interfaces into shaping how larger product experiences work. I began taking ownership of feature behavior, setup flows, and user journeys across the platform.

📌 What I do:

  • Define interactions, workflows, and product behavior for new and existing features.
  • Shape study setup flows and user paths with both usability and technical constraints in mind.
  • Collaborate closely with engineering and leadership on how features should function and fit into the broader product.
  • Create UX documentation, prototypes, behavior specifications, and long-running product improvements.
  • Stay hands-on with design while guiding larger decisions across the experience.
Toolkit:
Figma Documentation Prototyping Design Systems

✨ What I’ve learned: Product design is about seeing the whole system. A great experience is not just how one screen looks, but how every step, rule, and interaction works together.

Your Project Could Be Next

I've worked on UX, dev, and translations…
now I’d love to add your story here

Add your story

People first. Details always.

  • I design and build interfaces

    I design and build interfaces

    I move ideas from Figma to code – carefully, clearly, without forgetting the person on the other side of the screen.

  • I refine, iterate, polish

    I refine, iterate, polish

    Details matter – spacing, tone, logic, responsiveness. You feel the difference even when you don’t see it.

  • I collaborate across roles

    I collaborate across roles

    Designers, developers, researchers, managers – different perspectives sharpen the product, and I like being in the middle.

Projects That Connect the Dots

Selected work that shows how I turn complex ideas into clear, useful, and human-centered experiences.

University / Research Grant / Applied AI 2026 Submitted For Final Review

ToxiPred

ToxiPred is an applied AI platform for chemical toxicity prediction, created as part of a supported research project under the Slovak Recovery and Resilience Plan. I designed and developed the platform experience in Quasar and Python, building the interface and application logic that connect molecular inputs such as SMILES, CAS numbers, compound names, or InChI with existing prediction models and readable results.

This project taught me how to turn complex AI, chemistry, and model outputs into a usable product experience. It strengthened my skills in scientific software development, technical UX, and full-stack implementation.

University / UX Research / HCI 2025 Completed

Dark Mode UX Research Study

A UX research and HCI tooling project exploring how Dark Mode and Light Mode influence user behavior across real interface tasks. I designed and implemented custom browser extensions that created controlled visual conditions, allowing the study to compare decision-making speed, accuracy, confidence, workload, and perceived trust across selected platforms.

This project helped me combine UX research, interface design, and software engineering into one controlled study. It taught me how to turn a design question into a measurable experiment supported by custom-built tools.

What I am exploring currently

I’m exploring how design, code, and automation can work together instead of living in separate worlds — building my own WordPress architecture, experimenting with AI that reads user behavior, and pushing interfaces to feel sharper, smarter, and more alive.
