Hello, my name is Marcello and I'm a data professional with over seven years of experience in the field and over two years leading data analytics teams.

I have worked in companies of different sizes (from startups to multi billion companies), multiple fields (government, finance, retail, among others), both in Brazil and in the U.S. This also means I was able to work in different data maturity levels.

I like to help companies succeed with the use of data. I believe (and have seen) that the more data-driven the company is, biggest are the chances for the company to succeed.

My professional strenghts are programming (specially SQL and Python), data-related knowledge (like data modeling and data visualization), communication and leadership.

Hello there! I'm 24 years old and I've been passionate about technology since I was 13 years old. I've got interested in programming because of some games that I was usually playing, I wanted to create my own servers, in order to achieve this, I had to learn how to code, so I learned algorithms, starting with Java. Some years later I discovered the Web and got even more interested! Now, my main goal is to be a great developer, following good practices, writing readable and maintainable code. I'm the kind of developer that not only wants to know how to do something but why something is made that way, what happens behind a code/framework. I've been always improving my knowledge, I believe that you can always learn something new and you can always improve, do better. That's why I keep studying not only new subjects, technologies or frameworks but also mathematics, algorithms, new programming languages, clean code and etc. Portfolio: https://deyvidholz.dev
