Growth Obstacles

Problems This Solves

Your backend systems struggle to scale, and your codebase lacks standardized software architectures and security rules.

You want to migrate legacy .NET Framework platforms (4.x, WebForms) to modern, cross-platform .NET Core 8+.

Your APIs are slow and fail to process bulk database records during high concurrent transaction volumes.

You need C# developers who understand Dependency Injection, EF Core mapping, SQL Server indices, and Azure configurations.

Methodology

Our Proven Process

Clean Solution Setup

We structure the solution layers using Domain-Driven Design (DDD) and dependency injection patterns.

API & Core Logic Coding

We write ASP.NET Core Web APIs, define controllers, and write Entity Framework Core queries.

Database & SQL Indexing

We optimize SQL Server schemas, tune slow queries, and configure Redis caching layers.

Microservices Messaging

We implement event-driven models using RabbitMQ or Azure Service Bus to link separate services.

Azure Cloud Deployment

We configure Azure Key Vaults, launch App Services containers, and set up GitHub Actions.
