• Experience building web applications and services with ASP.NET Core (MVC, Razor Pages, or Web API).

• Experience working with relational databases, especially Microsoft SQL Server, including writing efficient T-SQL queries and working with stored procedures.

• Experience working with REST APIs, webhooks, JSON data structures, and third-party integrations.

• Working knowledge of front-end web fundamentals (HTML, CSS, and JavaScript) for building clean, usable interfaces.

• Understanding of data integrity, validation, error handling, and reliable system design.

• Ability to collaborate with nontechnical stakeholders, gather requirements, and explain technical concepts clearly.

• Strong attention to detail, especially when working with sensitive or business-critical data.

• B.S. in Computer Science or a related field, or equivalent practical experience in software development.

• Experience with ADP, NetSuite, payroll systems, ERP systems, HR systems, or school administration software.

• Experience building internal business applications, dashboards, approval workflows, or reporting tools.

• Experience hosting and deploying applications on IIS / Windows Server, and familiarity with Git for version control.

• Familiarity with data-access approaches such as ADO.NET or Entity Framework Core.

• Experience modernizing or migrating older .NET applications (for example, Web Forms to ASP.NET Core) — a plus, as we are actively modernizing our systems.

• Familiarity with authentication, role-based permissions, audit logs, and data privacy best practices.

• Experience with cloud platforms, scheduled jobs, background workers, or data pipeline tools.
