How I got here

My journey

I didn't start out as a Front-End Developer.

  1. Data & problem solving

    My early experience was around data, SQL, analytics and machine learning. That taught me how to understand information and solve problems, but I became more interested in the part people actually interact with.

  2. UI/UX & interface design

    That led me into UI/UX design. I started creating interfaces in Figma, learning about hierarchy, typography, spacing, user flows and the principles behind usable products.

  3. Frontend engineering

    Eventually, designing interfaces wasn't enough. I wanted to build them. I moved deeper into HTML, CSS, JavaScript and PHP, and later React, TypeScript and Next.js.

  4. AI-assisted product building

    Design and development are now part of the same workflow for me. I take ideas from UX and interface design through frontend development, testing and deployment. AI and automation support that process when they improve the product or workflow.

Today, I work at the intersection of design and frontend engineering — turning ideas into interfaces people can actually use.

design, then build, then ship

What I do

I can help with your next website, app or AI feature.

  • Websites & digital products

    I design and build responsive websites and interfaces from initial structure through production deployment.

  • AI features

    I integrate AI assistants, intelligent workflows and automation when they solve a real user or business problem.

  • User-focused interfaces

    I design responsive, accessible interfaces with clear hierarchy, predictable interactions and reusable components.

  • Performance & accessibility

    I build interfaces that are fast, accessible and production-ready, with performance, Core Web Vitals and technical quality considered from the start.

Built for production

Products I've helped design and build.

A selection of real products where I've contributed across interface design, frontend development and production delivery.

Good products should feel obvious.

I care about three things:

  • Usable

    Users should understand what to do.

  • Buildable

    Design decisions should translate cleanly into production code.

  • Maintainable

    The product should remain easy to improve after launch.

Beyond the screen

I like going places.

When I'm away from the screen, I like traveling, exploring new places and experiencing different environments. It gives me a break from building things and keeps me curious about how people, places and everyday experiences are designed.
