I build and secure .NET applications for financial and clinical operations.

Message

I've supported DVSOFT's Cloud9Ortho clinical application across .NET Framework and .NET Core, resolving production incidents through Jira and managing Amazon S3 storage and IIS deployments.

At Cooperativa de Ahorro y Crédito El Churqui, I built internal loan-tracking, ticketing, and reporting applications using ASP.NET MVC, Web API, C#, SQL Server, and PostgreSQL. I also introduced CQRS with MediatR and selected ADO.NET, Dapper, or Entity Framework based on each use case.

I've secured regulated financial environments with Shorewall, OpenVPN, Samba, OpenLDAP, and Kerberos, including a zero-disruption migration from UNIX SCO OpenServer to Linux CentOS. I also teach databases, programming, data structures, systems auditing, and information security, and have advised undergraduate capstone projects.
