Hi, I'm João Marcus Fernandes

Staff Software Engineer

Go | Node.js | Ruby | Python | MongoDB | React.js

I am a passionate software engineer and have been working since 2014. I've worked with companies in Brazil, North America (USA and Canada), Europe, and Asia. I have a degree in System Analysis and Development. I work mostly as a Back-end Engineer now, but in the past, I've worked with Beeon full-stack and Front-end. I also took many time holes as Tech Lead.

I have experience with JavaScript/Typescript (React.js, Next.js, Vue.js), Golang, Python, Ruby (Ruby on Rails and Sinatra), and MongoDB, and I primarily work with AWS and GCP.

I am an advocate for functional programming. I've worked with all major paradigms, but I value doing things Simple and Efficient, which I feel are characteristic of functional programming.

Arctouch} - Software Engineer - Staff

Software Engineer - Staff

Arctouch
Duration: 04/2022 - Present

After some time, I got promoted to Master Software Engineer (Staff Level), which meant my responsibilities expanded beyond my previous role as a Senior Software Engineer.

In addition to my technical expertise, I have taken on Tech Lead roles and contribute to the strategic development path for projects, and teams, working closely with managers to plan and chart strategies. I collaborate with the management team to identify areas of improvement and growth opportunities for the team members.

Mentorship has been a significant focus of my work. Through regular one-on-one sessions and group mentorship programs, I am helping them navigate challenges and equipping them with the tools they need to succeed.

I had to adapt to this role while still coding a lot, and I have been able to balance both roles. Most of the time, I worked in this role with Golang, React.js, and AWS. I have also worked closely with the DevOps team to improve our CI/CD pipelines and our code quality and security.
