My Journey


Hi, I'm Harison, and I live in São Paulo, Brazil.

At 17, I enrolled in what I believed was a basic computer skills course. I thought I would be learning the Microsoft Office suite to improve my job prospects. To my complete surprise, the course was actually about programming—and that twist of fate changed the entire course of my life.

A while later, I got my first professional experience at 99, the first Brazilian startup to become a unicorn and a major competitor to Uber in Brazil, and now a global player after being acquired by the Chinese company Didi Chuxing.
I started in SRE team, and later was invited to join the Software Engineering team, where I discovered what truly drives me: solving real-world problems through code and automation. And where I worked alongside engineers from Brazil, China, and the United States.

Technology found me by chance, but I chose to make it my own. I stayed because I've always believed it would play an ever-growing role in our lives. Being able to understand and build solutions that are part of that progress is what motivates me every single day.

Professional Experience

March 2021 - November 2021

Junior Software Engineer

99/Didi Chuxing

In this role, I continued working in the same area of software engineering, but with new tasks. One of them was investigating issues related to our cloud services and trying to solve them. To this end, I began to have access to AWS and some of the services we use, such as EC2, Elastic Beanstalk, S3, and others. Another task I began to perform was explaining some of our systems to the foreign members who had started working with us since the sale of the company.

February 2019 - February 2021

Software Engineering Intern

99/Didi Chuxing

The software engineering team I worked on was responsible for managing the B2B platform. In this role, I performed tasks such as developing new features for the platform, migrating legacy code to Java, creating Python scripts to automate services required by other departments or clients that hadn't yet been developed for the platform, and providing support to the support team in fixing bugs found in the platform.

July 2018 - February 2019
