Description of Engagement

The Minnesota Department of Information Technology Services (MNIT), partnering with Minnesota Management and Budget (MMB), is seeking one (1) full-time staff augmentation resource to perform .NET developer duties to develop a new Legislative Initiative web application.

The resource under this engagement will develop an application that integrates Microsoft’s ASP.NET Core MVC stack with Oracle 19c database services, generates PDF documents with iText 7, and is authenticated through an Oracle Cloud Infrastructure (OCI) API Gateway. The developed application must be production‑grade, highly secure, and fully accessible (WCAG 2.1 A and AA compliant).

Work will be performed off-site/remotely. The resource must be located within the borders of the United States and be available for work during regular business hours of 8:00 a.m. - 4:30 p.m. Central Time, Monday through Friday.

• Profile and tune performance – analyze slow Oracle queries and C# code, add indexes, rewrite logic, or implement caching. 
• Perform unit testing of developed code and resolve any bugs found.
