About this gig

Are you looking to automate your business workflow with a custom tool? I can help!

I am an IT professional and developer from the UTFSM (Chile), specialized in creating fast, modern, and practical web applications. Using technologies like Next.js, React, Tailwind CSS, and Python, I build custom solutions tailored to your specific needs.

What I can build for you:

  • PDF Generators: Automatic invoices, receipts, or budget tools.
  • Inventory Systems: Simple and effective stock management.
  • Business Tools: Custom dashboards to visualize your data.
  • Automations: Scripts to handle repetitive tasks and save you time.

Why choose me?

  • Modern Tech Stack: Fast and responsive designs that work on any device.
  • Efficient Delivery: I use advanced AI-assisted development (GitHub Copilot) to deliver high-quality code in record time.
  • Client-Focused: I build tools that are easy to use, even if you are not a "tech person."
