Freelancer profile translated to English.

Description

With 9 years of experience in multi-sector companies of all sizes, I can adapt to your environment while supporting existing teams. I am capable of guiding technical choices and supporting teams to convert business needs into value-delivering features.

With a foot in both the data and backend development worlds, using a multitude of languages and paradigms, I have developed a taste for software architecture and complex systems. Thus, in my previous assignments, I have contributed to two major data lakes, migrated monoliths to microservices architectures twice, written and maintained data pipelines, and created a complete technical foundation for development teams.
