About Rodrigo

I translate functional requirements into technical ones and generate high-quality deliverables.
I lead and organize teams to optimize resources.
I model scalable and efficient architectures.

During my career as a freelancer, I have held full-stack developer positions in startups, from creating a Big Data project from scratch in Scala and Spark to being a Technical Lead in various projects.

There are no problems for me, only challenges and new opportunities to grow.
