Senior Software Engineer at In All Media modernizing four legacy APIs and Windows Services from .NET 4.5 to .NET 10.
BrazilWhat I'm looking for
At In All Media, I migrated four legacy APIs and Windows Services from .NET 4.5 to .NET 10, preserving functionality and adding automated tests. I mapped each system with client stakeholders and owned the migration plan.
At Projétil, I cut deployment time by over 40% with Azure DevOps and Docker CI/CD pipelines. I also built a C# API architecture with Dapper and PostgreSQL, and migrated the frontend from React to Next.js.
At MB Labs, I developed a reporting feature to identify optimal locations for new businesses, integrating data with Power BI. I also maintained C# APIs and fixed cross-platform issues in a logistics mobile system.
At Undefined Technology, I contributed to a Kafka document-processing pipeline that generated and populated PDF templates, reducing manual workload. I also developed Zebra printer integration for automatically generating shipping labels.
