Methods are many,
principles are few.

I own the whole stack, from the first data model to the store release. One person who takes an idea to production without handoffs.

Service for brands

Your brand publishes every day, you only approve.

See the Acquisition Engine

You connect your own accounts. One idea becomes an article, a carousel and a vertical video, delivered to your drafts for approval.

About

Principle first. Shipped, not just designed.

I have been designing and building since 2018. It started with UX at Train this much, a company I co-founded, grew into UX/UI, then Flutter, then the full stack.

Today I found and ship my own products, including Principle Guy, a fitness platform live on iOS, Android, and web. I own the whole stack, from the first data model to the store release. You get one person who takes an idea to production without handoffs.

Methods are many, principles are few. I build on the fundamentals.

Web apps and sites. Marketing sites, landing pages, dashboards, and full web apps in Next.js and React.
Mobile apps. Cross-platform iOS and Android apps in Flutter, including native in-app billing.
Backend and infra. Firebase, Cloud Functions, Firestore, auth, and analytics wired to production.
End to end. From first principle and design through build, launch, and support.
