# Portfolio · Joris Mellegers > Recent work up close: Green Gold Label, Yogacentrum Leeuwarden, Nedanza, two internal configurators and JM Websites. ## Green Gold Label Certification for sustainable biomass. Certification, 2026. Green Gold Label is an international certification standard, running since 2002, with an office in Rotterdam. The work was spread over three WordPress environments on three addresses: the main site, the documentation and an emissions calculator. It became one site of nineteen pages, with an editing environment behind it. Every page is editable there, and the preview jumps to the spot on the page you are working on while you type. The participant register reads live from the data. The document library tracks the scheme documents by category, version and status, and the questionnaire opens up 72 questions by topic instead of one long scroll. What the editors do themselves goes beyond updating text. New scheme documents go in through a document manager of their own, the participant register is updated by uploading the official Excel file, the news carousel picks between the latest items and a fixed selection, and the forms arrive in their own house style with an export alongside. All of it with drafts, autosave and two roles, so nothing goes live by accident. During the move 169 old web addresses redirect to their new place, with twelve hostnames wired to the site. Not one dead link. ### In numbers - 3 → 1: environments merged - 924: fields editable in the CMS - 169: old addresses redirected - 72: questions opened up by topic How it went: We picked the best design version per page, together at their office.

Yoga, 2026. Two sites for the same woman. The Yogacentrum is the school: group classes, the schedule, who teaches. Her own site is the practice, for the work that happens one to one. The two sites point at each other. How it went: Two complete variants per page, Gallery and Editorial. Mirjam chose per page, and said what she wanted carried over from one into the other.

Mental health practice, 2026. Nedanza treats clients in Rotterdam and Delft, and trains therapists alongside that. Three pieces of work: the public site, the landing page for the academy, and the training portal behind a login. In the portal students follow their modules and see their progress, and everyone picks their own colour theme. Six of them. All six are below: click through and this block changes colour with you. How it went: A concept environment of its own, with 25 concept pages to choose from.

Custom tools, 2025. Besides websites I build internal tools. Not software for the outside world, but equipment for the people who work with it themselves: a form that does the maths, or a list that keeps itself up to date. ## JM Websites The agency. My own agency, 2025. JM Websites builds sites and automations for Dutch service businesses. Clients come in through Google Ads and a mail machine of our own. What the agency delivers next to a site is the things that happen afterwards: enquiries that get followed up on their own, documents that process themselves, and a monthly report that is already there before anyone asks for it.
