I design and build websites for coaches, artists, healers and heart-led humans, with a painter’s eye.

Design and code from one hand. I craft the look, build the site, and hand you a simple way to run it yourself.

What it does

A warm home for a Berlin midwife practice, where parents meet the team, browse courses, and reach out online.

What I did

Brand, responsive site and front-end (coded with AI), plus a custom CMS the team runs itself: courses, team, reviews and icons. I set up their SEO and Google profile, and moved them to their own hosting, which cut running costs.

Every project moves through the same five stages: a steady flow from first understanding to final hand-off.

01AttuneTune in to who the product is for, the business behind it, and where it needs to go.
02RevealMap the real problem, the people who will use it, and the material to work with.
03EmbodyGive it substance: identity, interface, and the code that makes it real.
04CohereMake every part flow together into one system that holds.
05InhabitHand off, so you can run it, keep it alive, and let it grow.

About

Background

My path hasn't run in a straight line, and yet it has a clear thread: a fascination with people and how they make meaning. A Master's in Political Science taught me to read systems and the forces that shape them; a year of Fashion Design turned that toward form, the body, and aesthetics; and as an abstract artist and ontological coach, I work with what sits underneath, who someone is and who they're becoming. Design is where it all converges: structure, aesthetics, and close attention to the human at the center. It's a unique mix, and it's exactly what lets me see a brand as a whole person rather than a template.

Ontological coaching sits underneath all of it: it taught me to listen beneath the brief, for who a client really is and who a product is truly for. Lately I bring that together with AI and code, building what I design rather than handing off a mockup, and carrying an idea from first sketch to a finished product with passion, depth, and creativity.
