Summary
Alexei Matrosov is a software architect with 11 years of experience specializing in .NET systems, modernizing legacy platforms and driving measurable operational improvements. Based in Helsinki, he has led teams and backend architecture for large-scale projects—most recently optimizing a hydropower production system to handle 10x more data while cutting AWS costs by 80% and migrating from .NET Framework 4.5 to .NET 10 and SQL Server to PostgreSQL. He blends hands-on C#, F# and Python development with infrastructure automation (Terraform, AWS) and pragmatic process design, including CI/CD and expression languages for time-series calculations. Known for “implement once and for ages” engineering, he thrives on converting messy legacy code into concise, maintainable systems and mentoring cross-functional teams.
