Felipe

Senior Software Engineer with 8+ years of experience building and maintaining backend systems with C# and .NET for financial services, healthcare, and logistics. Whether troubleshooting a production issue in a HIPAA-compliant telehealth platform or tracing a wrong number on a dashboard back through business rules to its source data, I have worked through complex problems with autonomy and an investigative mindset. I write and optimize complex SQL scripts and stored procedures, adjust backend features in ASP.NET Core MVC, and work with APIs, integrations, and asynchronous workflows on Azure.

My projects also include fuel delivery apps, a transport management system, an insurance CRM, a real-time trading dashboard, and a fintech platform.
