Production-Grade .NET Engineering for Enterprise Platforms
Atharva builds ASP.NET Core web applications, CMS platforms, e-commerce backends, and Azure-native services for US enterprise and mid-market clients. Work spans greenfield builds on .NET 8/9 and structured modernization of legacy .NET Framework codebases — using clean architecture, SOLID principles, and CI/CD from the start. Engineers average 12+ years of .NET delivery across integrations with Shopify, Amazon SP API, Salesforce, ERP systems, and payment gateways.
.NET Development Services
.NET Web App Development
We build custom ASP.NET Core web applications and RESTful/GraphQL APIs for reliability under load — using async/await patterns, Redis caching, and horizontal scaling on Azure or AWS. Covers dashboards, internal tools, customer-facing platforms, and third-party integrations with CRM, ERP, and SaaS systems. Delivered with Swagger/OpenAPI documentation, OAuth/JWT authentication, and integrated CI/CD pipelines.
.NET CMS Development
We deliver Umbraco 13+ and Orchard Core implementations for corporate websites, multi-brand portals, and content-heavy platforms — with headless delivery via REST/GraphQL content APIs where needed. Content workflows include draft/review/publish staging, role-based access, and SAML/OAuth/Active Directory SSO. Connects to Salesforce, Dynamics 365, HubSpot, and Shopify for content-driven commerce and marketing use cases.
.NET E-Commerce App Development
We build custom e-commerce backends for B2C, B2B, and multi-channel operations — on clean architecture with domain-driven design and PCI-DSS compliant payment flows via Stripe, PayPal, and Authorize.net. Product search runs on Elasticsearch or SQL Server Full-Text Search with Redis caching for high-throughput catalog queries. Integrates with Shopify REST/GraphQL APIs, Amazon SP API, SAP/NetSuite ERP, and major shipping providers including FedEx, UPS, and DHL.
.NET Migration
We perform structured upgrades from ASP.NET MVC and Web Forms on .NET Framework 4.x to ASP.NET Core on .NET 8/9 — refactoring deprecated APIs, converting SOAP/WCF services to REST, and modernizing Entity Framework and Dapper data layers. Migration applies CQRS, repository pattern, and dependency injection to replace tightly coupled monolithic code. Phased rollout uses feature flags and parallel running to keep production stable throughout.
.NET Cloud in Azure
We design and deploy cloud-native .NET applications on Azure — containerized microservices using App Service, Azure Functions, Cosmos DB, and AKS, with serverless patterns where the workload fits. Multi-region deployment with geo-replication and Application Insights monitoring is set up as standard, not optional. Azure DevOps pipelines, infrastructure-as-code, and Azure Key Vault secrets management are included for production-ready delivery.
