Words that cut through noise.

Ten years turning complex products into copy that lands. For B2B SaaS, healthcare tech, and AI companies that need a human voice in the room. Not the corporate-jargon kind. The kind that makes people stop, feel something, and act now.

“Not just words about AI. A working AI product, built end to end.

An AI cooking companion that turns a set of macros into a recipe you can actually cook. I designed the whole product: a build-time and cook-time split, a voice-first interface, and a macro-to-recipe flow. Under the hood: six agents across two CrewAI crews, one that prepares data and trains the model, one that reviews each recipe for nutrition, method, and equipment, plus a nutrition model trained on roughly 38,000 recipes. Built as an independent project during my AI Development course at Hebrew University, using Claude, CrewAI, scikit-learn, and Flask. Concept, architecture, and build, start to finish.

“The room isn't held by charisma, but by structure.

A course brand and landing page for a group-facilitation program aimed at therapists, coaches, and 1:1 practitioners stepping up to lead rooms. I wrote every line, designed every element, and built the page start to finish. The copy leads with the real fear behind the pitch: you've mastered private sessions, but a room full of people going silent is a different kind of exposed. Hero, curriculum, objections, and testimonials all written to sound like a practitioner who has actually held the room. One person, whole product: strategy, narrative, art direction, and front-end build in a single self-contained page. No template.

“Look Ma, no hands.” Pay with a single glance.

First Pay-by-Face solution arrives in the USA. Preciate Pay is a camera-based payment method, finally enabling customers of brick-and-mortar shops to pay without wallets, cards, or phones. The payment is completed with a single glance: the quickest, most convenient, and most sterile, hands-free way to pay. Not only does this dramatically reduce cart-abandonment and solve long queues, it frees staff for more important customer service work. Built by some of Israel's leading cyber security experts, shoppers' images are never stored, in full compliance with GDPR.

“The hallmark of any great city is its bicycle culture.

Lock with Confidence. Yet urban living can make it hard to enjoy cycling without proper security. Seatylock was formed by a group of passionate urban cyclists with one goal: creating the world's greatest bicycle locks. With backgrounds in security, design, and manufacturing, we understand what it means to worry about your bicycle's safety. Strictly adhering to principles of innovation, security, and design, we poured our heart and soul into ensuring Seatylock is engineered with only the highest quality materials for strength and durability.

The art of sounding human.

Concept & Product

Range is the point. Different pieces, different worlds. Some are spec concepts. Others are live products I named, wrote, and built end to end, using AI as a force multiplier to ship the whole thing, not just the words for it. Each created in its own voice.

For therapists, coaches & practitioners ready to expand their impact

You've mastered private sessions. Time to hold bigger rooms.

You've got 1:1 down. But a room full of people going silent? That's a whole different fear. Most practitioners are never taught how to hold group sessions. Learn it, and the room is comfortable from the first minute to the last.

See the work, not the wording.

Great people are terrible at describing themselves. The best engineer you'll ever hire called herself "detail-oriented" and left it at that. Kettle looks past the clichés to what someone can actually do.

I write across the whole spectrum.

A decade in-house and at agencies means the range is the point. From a single line of UX microcopy to a forty-page whitepaper, I move between registers, audiences, and formats without losing the thread.

01 · Product & UX

Words inside the interface

  • UI / UX microcopy
  • Onboarding flows
  • Error & empty states
  • Help Center & knowledge bases
  • Product tours
02 · Brand & Marketing

Words that move people

  • Websites & landing pages
  • Brand voice & manifestos
  • Video scripts & ad copy
  • Email campaigns
  • Naming & taglines
03 · Strategic & Technical

Words that carry weight

  • Whitepapers & technical docs
  • Investor & executive comms
  • Case studies & thought leadership
  • Pitch & sales decks
  • SEO & long-form content

Fewer words. The right ones.

Live & Published

& more

This is a curated slice. A decade of work lives in products, behind NDA's, or in formats that don't fit a link: internal comms, sales enablement, scripts, decks, and ghostwritten thought leadership among them. Full samples and writing tailored to your brief are available on request.
