About

Certified: ☁️ AWS Solutions Architect - Professional ☁️ AWS Solutions Architect - Associate ☁️ AWS Machine Learning Engineer ☁️ AWS SysOps Administrator ☁️ AWS Developer 🐧 Linux administrator (LPIC1) 📊 Datacamp Professional Data Scientist, Professional Data Analyst and Associate Data Engineer. Having a strong foundation in engineering and years of experience developing projects and solving problems across several industries, I transitioned to Software Engineer and Cloud Architect (AWS) with expertise in Machine Learning and AI. Thanks to the certifications I achieved plus the years of experience building on AWS, now I have a global view of the cloud and a deep understanding of +50 services. As a result, I am able to architect and develop systems on AWS from the scratch following best practices, balancing the tradeoffs of each architectural decision. I also have a solid foundation of data structures and algorithms, advanced Python programming skills (OOP, DDD, software architectural patterns, asynchronous programming), problem solving and computational complexity + MSc in Data Science and +130 courses completed at Datacamp platform.
