I'm a Full Stack Web Developer from Brazil, and I have 15+ years of experience in web development. I can be a strong driving force for improving the performance, scalability, usability, and reliability of development projects.

In 2003, I founded my own company (Mastop). I led that company until 2013 when I closed my office in São Paulo, and I've worked from Home Office since then.

I've worked with the Xoops CMS in the past. In 2007, I developed an open-source Content Module (which is used by a lot of sites until today) named “Mastop Publish” and a Spotlights Management Module named “Mastop Go2".
In 2009, I developed an e-commerce application for Small Businesses from scratch, and we started to sell it as a service.

I'm interested in entrepreneurship and creating scalable web apps with UI/UX that don't suck. I also love working to improve the performance and usability of web apps.

Currently, I work as an Independent IT Contractor/Consultant.

I study all the time. I read a lot, I work hard, and I love to learn new stuff.

Código Falado

In 2019 I started a channel to do Live Coding sessions twice a week as @CodigoFalado (Portuguese for Spoken Code). In 2020 my channel became the first Twitch Partner doing exclusively Live Coding in Brazil. My goal is not to sell anything but to create a developer community where we can all learn together. And it's growing pretty fast.

During the Live Coding sessions, I study about lots of different technologies while interacting with the audience. It has been a great experience, and I plan to keep doing it.

You can check me out on Twitch:

Most of the code I create Live is hosted on Github:
