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.

In my opinion, the most important thing in a professional is ownership. You need to feel like you own what you are building. That way, you will feel more motivated and also bring more value.

Currently, I'm learning Artificial Intelligence, specially Machine Learning, to bring even more value to the work that I do.

Hello! I'm Stefano, a seasoned Backend developer dedicated to simplifying lives through technology. With 6 years of expertise in Java and Node, along with 5 years on Azure and 3 years on AWS, I excel in crafting clean code, solving complex problems on a daily basis.

My proficiency extends to unit testing, event queues, and I bring extensive experience in integrating systems, ensuring smooth and efficient communication between diverse components. Additionally, I have a proven track record of leading teams to successful solutions. Fluent in English, I contribute to dynamic teams and innovative projects.

My goal is to secure a role as a Backend Developer, Tech Lead or Java Developer, leveraging my skills for impactful solutions.

Some achievements:

•Enhanced payment processing for a prominent company by developing a high-impact payment API product, resulting in a significant increase in payment rates.

•Optimized various projects by implementing cache strategies, leading to a remarkable decrease in CPU consumption and response time by over 60%.

•Revamped the approach to writing unit tests for Java Microservices, elevating the quality and efficiency of testing processes.

•Worked at Brazilian Stock Exchange.

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

I’m passionate about automating processes, maintaining reliable systems, and helping developers deliver their
code.
