Composition & hierarchy
One clear focal point, a logical reading order, balanced whitespace.
competing focal points, clutter, a buried key message.
I design brands and packaging that sell, dashboards teams actually use and AI visuals that are ready to publish. 13 years for Porsche, Deloitte and Coca-Cola, across Europe, the US, Australia and New Zealand.








I combine strong design fundamentals — composition, typography, colour and hierarchy — with hands-on generative AI. I create, direct and critically evaluate AI imagery and video, and I know when an image is ready to publish.
Three things I deliver, measured across brands, products and dashboards. Click any number to see the project behind it.
Visual AI & content · ORIGAIN, 2026
My own high-performer retreat concept, built end to end with generative AI: concept, copy, logo, imagery, brand world and video, edited into a 12-slide pitch deck.
Generating… 0%
Every ORIGAIN asset started as a structured prompt and went through several rounds of direction. Each prompt is built from the same five parts, so changes stay deliberate and results stay comparable.
Directing the image
Technically clean, but the story is wrong. An athlete alone with a barbell could be any fitness ad.
DirectionPremium, editorial, golden hour. Result: technically right, story wrong.
Same light, same setting, same athlete. One change, and the image now tells the story of guided, personal training.
DirectionChange one variable only: add a coach. Keep light, setting and athlete.
The opening image of the deck, brought to life as a Runway Gen-4.5 clip and checked frame by frame for motion, anatomy and light.
ReviewFrame by frame for motion, anatomy and light before it went into the deck.
Image, version 1
The retreat, in motion
The full generated shot had a flaw that is easy to miss on a first watch: one guest walks across the surface of the pool. Instead of publishing it, I cropped the clip to a 4:5 social format that keeps the story, the fire, the ocean and the people, and leaves the error out.

Concept, brand world, persona story and the retreat experience, all generated and directed with AI. Happy to walk you through it.
Quality criteria
Six criteria I apply to every review: my own work, my team's, or AI-generated output. I also review copy and cultural fit in German, English and Spanish.
One clear focal point, a logical reading order, balanced whitespace.
competing focal points, clutter, a buried key message.
Legible, correctly spelled text and a consistent type scale.
garbled or misspelled generated text, too many type styles.
A purposeful palette and enough contrast for text to read.
text on busy imagery, low contrast, off-brand hues.
Correct logo use, tone and visual language of the brand.
a generic stock look, distorted logos, inconsistent style.
Readable at the target size, a clear call to action.
tiny copy, weak calls to action, meaning carried by colour alone.
Believable light, materials and product details.
warped packaging, anatomical errors, broken perspective.
Your turnRate this retreat image on three criteria, then compare with my review.
My verdict: strong craft, wrong story. It reads as a gym, not a retreat. Fix: change one variable and add a coach, see version 2 above.
Case study
A self-initiated AG1 key visual. The raw generation had no usable typography, a clumsy crop and broken copy on the pouch. I scored it against my six criteria and rebuilt it step by step. Drag to compare.

From critique to data
Design critique is only useful to engineers when it is structured. I write every finding twice: once as a designer would say it, once as an annotation with criterion, failure mode, severity and a hypothesis for the cause.

Design critique
The brand name is misspelled as “ORGAIN” in the profile header and under the logo. A reader would not notice at a glance, but it breaks trust the moment they do.
Annotation for the model team
{
"asset": "origain_social_profile",
"region_px": [1188, 626, 1292, 666],
"criterion": "typography",
"failure_mode": "brand_name_misspelled",
"severity": "blocking",
"score": 1,
"hypothesis": "small-scale text drifts from the prompt string",
"fix": "render brand text as an overlay; add to eval set as a negative example"
}
Design critique
The logo mark is drawn slightly differently on cap, shirt and bottle. Each looks fine alone; together they read as three different brands.
Annotation for the model team
{
"asset": "origain_merch_set",
"regions": 3,
"criterion": "brand_alignment",
"failure_mode": "logo_inconsistent_across_items",
"severity": "major",
"score": 2,
"hypothesis": "model redraws the mark per object instead of reusing it",
"fix": "composite one master vector; test consistency across a multi-object prompt"
}
Design critique
Neck labels show illegible pseudo-text instead of the wordmark. Small, but exactly the kind of detail a premium brand gets judged on.
Annotation for the model team
{
"asset": "origain_merch_set",
"regions": 2,
"criterion": "craft_realism",
"failure_mode": "pseudo_text_on_small_labels",
"severity": "minor",
"score": 3,
"hypothesis": "fine text on fabric below legible resolution",
"fix": "mask label areas; place the wordmark in post"
}Style taxonomy
To steer a model, “premium and calm” has to become attributes it can learn. Here is the ORIGAIN opener, broken down. Hover or tap an attribute to see where it lives in the image.
The same attributes become labels for annotation, filters for evaluation sets and building blocks for prompts.

Return on design
When dashboards are clear and design systems are reusable, people find answers faster and stop rebuilding layouts. That time goes back into their core work. This is how my work raises productivity and the return on every project.
