> Client work

Need more than components? Hire the engineer who builds them.

I build for clients too, from a single landing page to a full product or an AI feature. Every build ships with its code in your repo, per project or on retainer.

> How I work

From the first email to launch.

  1. Tell me what you need

    Write in through the contact form or by email: what you are building, and where you are stuck. I reply by email.

  2. Get a written quote

    After a short call or a few emails, you get a quote with scope, price, and timeline. That quote is what you pay: 50% to start and 50% before launch.

  3. See it every week

    Every week you get an update and a preview link to click through, in a shared Slack channel or the tool your team already uses.

  4. Launch with your code

    The code lives in your repo, built from the same tested components as Cortexcn. Every project includes 30 days of fixes after launch.

Built with

  • Next.js
  • React
  • TypeScript
  • Tailwind CSS
  • Node.js
  • PostgreSQL

Per project

A fixed scope and a written quote. Landing pages, websites, stores, and web apps each have a package with a starting price.
