About this gig

Are you looking for help with your ASP.NET Core backend, REST API or database-driven application?


I can help you build, fix or improve backend features using .NET, C#, ASP.NET Core Web API, SQL Server, PostgreSQL, REST APIs, authentication, business logic and API integrations.


I can help with:

- ASP.NET Core Web API development

- REST API endpoints

- CRUD operations

- SQL Server or PostgreSQL integration

- Backend bug fixes

- Authentication or role-based logic

- API integrations and webhooks

- Business rules implementation

- Code organization and basic documentation


My main focus is backend development. I can work on existing projects or build small backend modules from scratch, depending on your requirements.


I have experience working with business systems, document workflows, ERP-related solutions, APIs, webhooks and process automation.


Please contact me before placing an order so we can review your requirements, confirm the scope and choose the best package for your project.
