The Maison
A house built on craft,
not compromise.
Since 2017 I have designed, built, and shipped complete products across web, backend, and mobile — owning every step from idea to production. I lead teams with a single standard: deliver real, lasting value.
Today my work centres on AI — the Vercel AI SDK with TypeScript, Spring AI with Kotlin — bringing intelligence into products with the same rigour a watchmaker brings to a complication.
The Founder · Dan Zabrotski
Savoir-Faire
Three disciplines. One hand.
Every piece leaving the house passes through the same hands — from the foundation beneath it to the intelligence within it.
I
The Architecture
Backend & Systems
Foundations engineered to outlast trends — resilient services, considered data models, and infrastructure that holds under weight.

- ◆NestJS
- ◆PostgreSQL
- ◆Redis
- ◆AWS
II
The Interface
Web & Mobile
Surfaces polished until they disappear — interfaces across web and mobile where every interaction feels deliberate and effortless.
- ◆Next.js
- ◆React Native
- ◆TypeScript
- ◆Tailwind
III
The Intelligence
Applied AI
Intelligence set into products like a complication into a movement — purposeful, precise, and quietly powerful.

The Collection
Three houses. One standard.
Products conceived, engineered, and maintained end to end — each one a complete piece, from first sketch to production.
The Founder
Founder. Engineer. Craftsman.
Age the craft began
Age of first position
Houses founded
Industries served
The craft began at fourteen; by sixteen it was a profession. What followed was nearly a decade of building — web, backend, mobile — across fintech, foodtech, fitness, automotive, and SaaS, always owning the work from first sketch to production.
But an engineer becomes a founder the day he refuses to hand the vision to someone else. Three houses — Speekl, Traque, and Brymee — were each conceived, designed, engineered, and brought to market by one pair of hands, and each is still kept to the same standard today.

The Code of the House
Principles, kept.
I
Ownership, end to end
From first sketch to production, every piece is carried by one pair of hands. Nothing is handed off; nothing is left half-finished.
II
Longevity over novelty
Technology is chosen the way a watchmaker chooses steel — for how it endures, not for how it glitters this season.
III
Detail is the product
The seam no one sees is finished with the same care as the face everyone does. Rigour in the invisible is what people feel as quality.
IV
Intelligence with restraint
AI is set into a product only where it serves the wearer — purposeful, precise, and never louder than the work itself.
