Need +4 years experienced developer. I need ongoing, long-term help maintaining and expanding a suite of custom business web applications that run on a .NET Core back-end with MS SQL Server and strong [login to view URL] services. Work will range from creating new REST endpoints and background jobs to refining existing data models, tightening security, and smoothing out deployment pipelines. You’ll step into an active codebase and deliver production-ready features: clean, well-tested C# and JavaScript/TypeScript, optimized SQL queries, and clear documentation so future sprints stay painless. Each release is considered done when unit tests pass, automated builds succeed, and the update can be deployed to our staging server without breaking existing functionality. If you thrive on writing solid .NET Core APIs, crafting efficient stored procedures, and occasionally jumping into asynchronous Node.js tasks, this partnership should fit you perfectly.
