Alessandro Marin, PhD

Software Developer

Physicist with strong competencies in software development, machine learning, scientific research, and technical troubleshooting.
At Hafslund Eco Vannkraft and in 10+ years of corporate and academic experience Alessandro developed a range of skills in machine learning (including NLP, RAG), programming and data analysis (Python), cloud development (Azure DevOps, CI/CD pipelines), data acquisition from different sources (Web Scraping, REST API, ETL), and data management (Terraform, Azure Data Factory, SQL Database, CI/CD data pipelines, Azure Blob Storage, Azure Service Bus).
As a technical support specialist at InterSystems Co., a global company in database (SQL and NoSQL) and healthcare technologies, Alessandro became proficient in handling technical challenges with data (relational models, data architecture, data flow) and communicating with end-users.
Eager to work in a role within data science and software development.
