One builder.Two AI agents.Shipped in days.

I design, build and launch SaaS products, mobile apps and 3D experiences, working AI-assisted with a crew of two agents that build and market while I drive product, design and final quality.

[01]the crew

A team of three. One is human.

Every project runs through the same pipeline: I set direction and own the product. My two AI agents multiply execution speed without lowering the quality bar.

[02]what I build

SaaS. Mobile. 3D.

Three kinds of products, one method: smallest valuable version first, live in days.

01

SaaS products

Full-stack web apps: auth, billing, dashboards, AI features. Built end to end and deployed to production.

Next.js · TypeScript · Vercel

02

Mobile apps

iOS & Android apps from prototype to store, with the same shipping speed and the same quality bar.

iOS · Android

03

3D experiences & games

Browser games and interactive 3D worlds. The background of this very page is a live WebGL shader.

WebGL · Three.js · Shaders

[04]process

From idea to live in three moves.

01

Scope clearly

Define the smallest version that creates real value, nothing more.

02

Ship fast

Me and my AI crew in a tight loop: one agent builds, the other preps the launch. A usable MVP in days, not months.

03

Iterate wisely

Improve with real usage and measurable outcomes, release after release.

[05]background

Product manager first, builder always.
