ASP.NET Development Services
Atharva ITS builds robust ASP.NET Core backends and secure REST APIs for e‑commerce platforms, B2B portals, mobile apps and internal systems, modernizing legacy .NET applications into scalable, cloud-ready services that support long-term business growth
Why Choose Our ASP.NET Development Services?
High-performance backend architecture: ASP.NET Core applications are designed with async I/O, efficient Entity Framework Core queries and caching (Redis, in-memory) to deliver fast response times and handle concurrent requests without performance degradation.
Cross-platform and cloud-ready: We design ASP.NET Core services to run on Windows or Linux, in containers or on Azure App Service, with deployments tailored for Azure, AWS or on-premises environments so your backend remains portable and future-proof.
Secure by design APIs and services: Authentication (JWT, OAuth2/OIDC), policy-based authorization, input validation, rate limiting and secrets management (Azure Key Vault, AWS Secrets Manager) are built into your APIs from day one to reduce security risks.
Clean, maintainable architecture: We follow SOLID principles, layered/hexagonal architecture and testing practices so your ASP.NET Core codebase stays readable, testable and easier to extend as your business and integrations evolve.
