What I'm looking for

I’m looking for a role in information technologies where I can develop my analytical ability, keep growing through hands-on work, and help the company improve areas tied to continuous quality improvement.

I’m an IT Manager and PIASA head of the systems department, directing projects and keeping my systems up to date. I build and maintain integrations, including an interface between Alleatto ERP and WMS with an API in C# and a SQL Server database.

I also drive application development across teams and platforms: I manage a new web application in C# with the ASP.NET framework and a SQL Server database, maintain and extend ERP modules in Visual FoxPro with SQL Server, and support a Flutter mobile application backed by SQL Server. I develop and maintain reports on IIS using C# and SQL Server.

Beyond applications, I’m responsible for infrastructure and company applications with 3 people reporting to me—handling verification/replacement of operational computers, database server and network server maintenance, and Active Directory support. Previously, I worked as a Programmer and Development Engineer supporting end users and production systems using C#, SQL Server, Delphi, and Oracle, and earlier in Java roles using frameworks like Struts and Spring.
