At Moosend, I design, build, and run distributed .NET 8 and ASP.NET Core microservices on AWS. I implement service authentication with OAuth 2.0, OpenID Connect, JWT, mTLS, and certificate-based authentication.
I led upgrades of core .NET services and own build and release pipelines in TeamCity and Jenkins. I also tune database performance and maintain BDD test coverage with Gherkin.
At Intrasoft International S.A., I delivered full stack loan-sector web solutions for the National Bank of Greece in a regulated banking environment. I also designed and documented REST APIs and built Selenium test automation.
