What I'm looking for

I am looking for opportunities that challenge my technical skills and foster growth.

My name is Bernardo Cruz, and I am a dedicated Backend Developer with a strong foundation in solving complex problems and analytical thinking. I graduated from Universidade Federal Fluminense, where I focused on multiobjective optimization methods applied to chemical processes. My journey in backend development began at Raro Academy, where I excelled in my coursework and quickly transitioned into professional roles.

Currently, I am working at Raro Labs, where I have been instrumental in developing a CRM using NestJS, focusing on integrations, APIs, and serverless microservices with AWS. My experience spans across various projects, including refactoring legacy systems and implementing unit tests to enhance application efficiency and security. I thrive on technical challenges and am committed to continuous learning, always seeking efficient solutions that positively impact products and businesses.
