I ship products end to end, from research to UI. I also build the AI systems that handle the production, while I keep the taste.
I've worked with teams on every continent and everywhere, the same lesson: "obvious" is very local. Good design starts from where the user stands, not where the designer sits.
A simple AI workflow for design: Claude + MCP agents handle production, token sync and documentation. I keep the thinking and the taste.
...once upon a time, said Maria Skłodowska-Curie, the first woman ever to win a Nobel Prize. She discovered Polonium and named it after the country we both come from: Poland. The discovery made her immortal. It also killed her: she carried radium in her pockets, not knowing what it could do.
Do I fear AI? Of course. Any tool this powerful deserves the useful kind of fear: the kind that makes you build carefully. We build as human beings, for human beings, not by chasing every trend without understanding what comes next. So I bet on stability, because it doesn’t matter how brilliant something is if it collapses in days.

Whether you agree with mine or see it completely differently, I'd love to hear it. And if it feels like we could be a good match, even better.

Case study · Brand & UI System
Netomi is a California startup backed early by OpenAI co-founder Greg Brockman, with over $160M raised after a $110M Series C led by Accenture Ventures. It sells autonomous customer-service AI to enterprises like Sephora, WestJet and MGM Resorts. I built its end-to-end brand and UI system by hand, in the pre-AI era.

Netomi · California
Netomi resolves customer conversations end to end, across chat, email, voice and social, for companies whose support volume is measured in millions. The buyer is an enterprise CX leader who cannot afford to get it wrong.
The brief: make a young AI company look like the safe, calm, inevitable choice for a Fortune 500 buyer. Every part of it was drawn by hand, before AI tooling existed for this kind of work.
Put ten enterprise AI companies side by side and you get one brand: dark blue, a purple glow, a floating orb. The whole system had to signal trust without looking like every other chatbot vendor, and it had to hold up in a procurement review, not just a launch post.
Four flat tones with black leading, gradient kept to the background, one accent at a time. Photography breathes through black. Everything defined as rules, so every team ships the same brand without asking me.
Enterprise buyers do not buy hype. They buy calm.
A brand only counts if it survives inside the product: agent console, live voice sessions, dense queues and dashboards. This is where most brand systems break.
One brand from favicon to keynote, adopted across every customer-facing team. Sales decks that took days now ship the same day, because the templates carry the brand for them. Years later the system still runs.

Firework · Silicon Valley
Firework is a Silicon Valley video-commerce platform backed by SoftBank, turning product pages, apps and in-store screens into shoppable video for 1,500+ brands, including Samsung, JD Sports and Kylie Cosmetics. Two redesigns, one machine, and a lot of learning about what actually moves the needle.
The first rebrand fixed how the company was read. The second answered a harder question: how do you add colour and energy without losing enterprise trust, in a market where AI had made “clean tech” the new generic. Then I looked at my own workflow and found the real bottleneck: design was a queue, every deck and one-pager waited on me. Production is repeatable, judgment isn’t, so I automated the first and kept the second.
Challenge
Outdated by a decade, not a year. Heavy layouts, messy type, and social-video formats everywhere, so prospects read a commerce platform as a TikTok agency.
Solution
Strip every agency signal and rebuild on an enterprise spine: black, white, one blue, hard grids, product first. The product is the hero, the brand is the frame: serious enough for a Samsung procurement call, alive enough for video.
Shipped across the site, decks, socials and five conference booths. The TikTok question died.
Then the market moved: AI ate the category and “clean tech” became the new generic. New question: colour and energy without losing enterprise trust. Boards went through elimination rounds against fixed criteria: does it survive a junior marketer’s deck, does it scale from a booth to a favicon. Black-white-blue stays as the spine, colour arrives as an event.
A brandboard is a promise; a system is a contract. Tokens, components, specs written for non-designers; then Claude and MCP wired to one shared Drive folder. Collateral Maker studies the decks and templates I built by hand and reproduces them on demand. Sales asks, it ships, on brand. No ticket.
Production is repeatable, judgment isn’t. So I automated the first and kept the second.
Three teams now make their own decks, one-pagers and campaign pieces, every one on brand, without a single design ticket. The hours that used to go into production go into direction.
The brand in the wild, all produced from the same system.

Dossier Parfait · Paris
Dossier Parfait is a Paris-based proptech recognised by La French Tech. It replaces the paper rental dossier with source-verified solvency, tenants judged on real financial habits rather than a single payslip. As the product designer, I designed the brand, the marketing site and the full UI system.
In France, renting starts with a folder of paper, easy to forge,, painful to assemble and quietly discriminatory: one payslip outweighs years of reliable behaviour. Dossier Parfait connects directly to the source (banks, tax authority) and produces one verified dossier that tenants own and landlords trust.
I took this one personally: I’m an immigrant myself, and I’ve been the applicant whose file gets passed over before anyone reads it. As the sole product designer alongside the founding team, I took the product from concept to a coherent system across brand, mobile, tablet, web and marketing.
The problem
The rental market judged people in seconds, on one number. A single payslip decided everything, so lower-income tenants, immigrants, freelancers (anyone with a foreign name or a short local history) were screened out before their file was even read. Years of paying rent on time counted for nothing, and the paper folder itself was easy to forge and painful to assemble.
Solution
Verify solvency at the source and read the whole financial picture (income, routines, savings) instead of one document. One electric blue (#275AF5), Avenir, and a mark that folds the D around an upward arrow: a brand calm enough for finance, warm enough for the people the old dossier used to screen out.
Shipped across mobile, tablet, web, the marketing site, social, out-of-home and print.
Product. A dark, focused UI: onboarding, bank connection and a verified Dossier 2.0 in minutes, consistent across mobile, tablet and web. Key decisions: a three-step flow keeps legal consent in context, chips replace dropdowns for one-hand input, and a full alert system covers expiry, errors and empty states.
Brand. The colours started with Réann: the electric blue and the soft violet were her instinct, and she was right. My job was to make them read professionally without losing the warmth: one disciplined blue (#275AF5) as the spine, violet as the accent, black and white doing the heavy lifting, Avenir throughout, and a mark that folds the D around an upward arrow. Friendly enough for a stressed tenant, serious enough for an agency call.
Collateral. The same system carries off-screen. One electric blue, Avenir and the folded-D mark do all the work across every deliverable: QR-driven social ads and Instagram content, an out-of-home campaign in the metro, merch, and a full print suite: stationery, letterhead, business cards and the annual report binder. Everything comes from the same tokens, so the brand reads identically from a favicon to a four-metre poster.
Two awards in one year for a product built to make renting fair. Not bad for a folder of paper nobody wanted to fill in.
