How we work together

Never hired a developer before? Here's how it works, with no surprises along the way.

  1. Conversation

    You tell me what you need over WhatsApp or a call. I ask questions until I understand the problem, not just the request.

  2. Proposal and prototype

    You receive the scope, timeline and price in writing. For larger projects, a clickable prototype to review before you approve.

  3. Development

    I build in short iterations and share a link so you can follow along and give feedback as the project takes shape.

  4. Launch and support

    I publish it on your domain, set everything up and show you how to use it. After launch, I'm still around for adjustments.

The person behind it

Zion S. Ferreira Lemos

ZionWareX is my studio. I am a developer based in Espírito Santo, Brazil, and I build every project end to end: design, code, deployment and support.

I build business websites that generate leads, custom web apps that take companies off spreadsheets, and redesigns that modernize what already exists, always focused on results for your business.

I enjoy projects with a clear owner and a clear problem. You work directly with me, with no middlemen, and always know where each stage stands.
