Freelancer profile translated to English.

Description

Full Stack Developer specialized in Next.js, Node.js, and MySQL.

Coming from 15 years in hotel management, I understand the real needs of a business before writing a line of code. I am currently developing a complete hotel management system (PMS) with modules for reservations, cash register, parking, groups, and more.

I have also undertaken freelance projects such as a website for a school's PTA and online stores for third parties. You can see more projects in my portfolio: stackbp.es

I can help you with:

Web applications with Next.js and React
REST APIs with Node.js and Express
MySQL databases
Online stores and e-commerce
Clean interfaces with TailwindCSS

I am looking for projects where I can add value while continuing to grow as a developer. If you have an idea or need a website, landing page, online store, or small application, let's talk.
