Inventory, leads and sales — all in one place

Inventory, leads and sales — all in one place

A business that relied 100% on Facebook Marketplace now has its own sales channel: it ranks on Google, captures leads automatically, and the owner manages everything from their phone.

Client review

“It has been extremely helpful. Before having a website, I had to post on Facebook, and every message I received through Meta would cost me. Now I simply share the link, and clients go directly to my website, where everything is set up and they can contact me from there. The leads section has also been very useful for keeping track of clients who would normally get lost in WhatsApp chats. I really like how easy it is to manage my website, and the amount of time it saves me is significant. 10/10. I highly recommend it—very professional and punctual.”

My Difference

Most developers deliver a site and vanish. I build tools that work for your business when you're not around. Every site I deliver includes three things most don't offer together: SEO so Google finds you without paying for ads, an admin panel so you update your content without depending on anyone, and real support after launch. That's what I build.

How do I develop your projects?

  1. 1

    Initial meeting

    I talk with you to deeply understand your brand, your goals, and what you expect from the website. This stage allows me to align expectations and build a solid foundation for the project.

  2. 2

    Custom proposal

    I create a detailed proposal tailored to your needs. It includes structure, functionalities, estimated timelines, and costs. Nothing generic — everything designed specifically for you.

  3. 3

    Development

    I transform the proposal into a real website: fast, optimized, and built with clean code. I integrate the necessary features, ensure performance, and prepare everything for launch.

  4. 4

    Review and launch

    Before launching the site, I present it to you for review and final adjustments. Once approved, I publish it online with every detail refined and working perfectly.

  5. 5

    Support

    I do not leave you alone after launch. I offer support to help with updates, maintenance, or any questions that may arise.
