Available for agency collaboration

Frontend development
for digital agencies.

I help agencies turn designs and ideas into clean, responsive, production-ready websites — as an external frontend or WordPress developer.

Extra capacity when your team needs it.

I can plug into an existing agency workflow and take ownership of implementation work.

Quality standards

What every project gets.

The same checks before every handoff — from a single landing page to a full WooCommerce store.

  • Pixel-perfect

    Checked against the Figma design at every breakpoint.

  • Cross-browser

    Chrome, Edge, Firefox, Safari and iOS; layouts from 320px up.

  • Fast

    Lighthouse 95+ and Core Web Vitals in the green.

  • Accessible

    WCAG 2.2 AA: contrast, keyboard, screen readers.

  • Tested

    Linting plus Playwright smoke and visual tests where the project needs them.

  • Clean handoff

    Readable code, Git history and short docs your team can maintain.

Agency workflow

Your client.
Your workflow.

I work as an extension of your team, not as another layer between you and the client.

  1. You provide the design

    Figma, design system, existing website or project requirements.

  2. I handle implementation

    Frontend, WordPress, responsive behaviour and required interactions.

  3. Your team reviews

    I work within your existing tools and iterate from your feedback.

  4. You deliver the project

    Your agency keeps the client relationship and project ownership.

Flexible collaboration

One developer.

Agency overflow

Ongoing support

White-label
