More than just code
A team that builds more than just great software
When a business application handles customer records, orders, permissions or financial transactions, the backend needs to do more than return data. It must apply business rules consistently, protect sensitive operations and stay dependable when something goes wrong. Our ASP.NET Core developers work on the parts of software that users may not see but rely on every day: C# APIs, database access, authentication, integrations and background processing. We can help build a new backend for a web or mobile product, extend an existing .NET system, investigate performance problems or plan a gradual move away from older .NET Framework code. Work can include Entity Framework Core, SQL Server or PostgreSQL, role-based permissions, logging, tests and deployment checks. Before suggesting changes, we look at what your application already does, which workflows cannot be interrupted and where the real risks lie. That helps us deliver improvements your team can maintain long after the first release.

How to hire a ASP.NET Core developer
A practical selection process gives your team enough evidence to review skills, communication and delivery fit before access and ownership are assigned.
- 01
Show us the application and its challenges
We discuss your APIs, databases, security requirements and the workflows that matter most, whether you are starting fresh or changing a live system.
- 02
Review relevant C# experience
Meet developers whose experience fits your architecture, such as EF Core, SQL Server, Azure, authentication or high-volume integrations.
- 03
Talk through a real backend scenario
Use one of your actual requirements to discuss transaction handling, API design, failures and maintainability—not just framework terminology.
- 04
Begin with a clearly scoped feature
Start with an API, integration or module with agreed acceptance criteria. Review code, tests and deployment considerations before moving to the next phase.

View pageFrequently asked questions
Everything you need to know before hiring ASP.NET Core developers.
Can you help migrate an older .NET Framework application?
Yes. We begin by reviewing framework dependencies, third-party libraries, database access and critical features. Then we can plan a staged migration to modern .NET where it makes sense, instead of assuming every application needs a full rewrite.
Do your ASP.NET Core developers work with SQL Server and PostgreSQL?
Yes. Depending on the project, the work can include EF Core, schema changes, SQL queries, indexing, transactions and integration with an existing database. We confirm the relevant database experience when discussing developer profiles.
Can you build authentication and role-based permissions?
Yes. ASP.NET Core applications can use token-based authentication, authorization policies, permission checks and audit logging. We define the security requirements before implementation, especially for administrative and sensitive operations.
How quickly can we hire an ASP.NET Core developer?
The timeline depends on the level of experience, technical requirements and availability. Share your stack and scope, and we can explain the profile review and onboarding steps appropriate to your project.
Can I speak with the .NET developer before the engagement?
Yes. You can review relevant experience and discuss your architecture or a real development challenge before making a decision.
Will we own the code and database changes?
Ownership of source code, scripts, documentation and other deliverables is defined in the engagement agreement. We recommend confirming repository access and handover expectations before work starts.
