Microservices & API Architecture
Design and implementation of resilient RESTful and gRPC services using ASP.NET Core, OpenAPI, and event-driven patterns. We define clear contract versioning, authentication, and throttling strategies, apply domain-driven design for bounded contexts, and integrate messaging systems like Kafka or Azure Service Bus for eventual consistency. Emphasis on automated tests, API gateways, and scalable deployment models to support high-throughput enterprise workloads.
Cloud, Azure & Container Modernization
Migrate and modernize .NET backends to Azure with containerization and serverless where appropriate. Our engineers implement AKS, App Services, Azure Functions, IaC with Bicep or Terraform, and cost-optimized architectures. We deliver CI/CD pipelines, container registry workflows, secrets management, and platform observability so applications scale reliably while reducing operational overhead and cloud spend.
Performance Optimization & Troubleshooting
Deep performance tuning for .NET apps: memory leak analysis, GC tuning, thread-pool and async/await fixes, and removing blocking calls. We optimize EF Core queries, add batching, indexing, and caching (Redis) to reduce DB load, profile with dotTrace/NDepend, and perform load testing and capacity planning to prevent hangs and server overload under real-world traffic.
Data Engineering & Database Design
Database architecture, schema design, and data access optimization for OLTP and analytics. Expertise with SQL Server, EF Core migrations, stored procedures, indexing strategies, partitioning, ETL pipelines, and NoSQL alternatives. We ensure transactional integrity, design for scale, implement backup/DR strategies, and integrate data flows with BI, streaming, and analytics platforms.
Legacy Modernization & System Integration
Modernize monoliths and integrate legacy systems with modern .NET APIs. We apply the strangler pattern, wrap legacy functionality with secure APIs, upgrade .NET framework versions, refactor technical debt, and handle ERP/CRM/mainframe connectors. Focused on incremental delivery, risk mitigation, and preserving business continuity during migration.
Security, Compliance & Automated Testing
Security-first backend engineering covering secure coding practices, OWASP mitigations, authentication (OAuth2/OpenID Connect), authorization, JWT management, data encryption, and compliance for HIPAA, PCI, and financial regulations. We implement automated unit, integration, and contract tests, static analysis, and SAST/DAST pipelines to catch vulnerabilities early.
DevOps, CI/CD Pipelines & Observability
End-to-end DevOps for .NET backends: Git-based workflows, Azure DevOps/GitHub Actions, container builds, Helm charts, and blue/green or canary deploys. Implement observability with Application Insights, Prometheus, Grafana, centralized logging, distributed tracing, SLIs/SLOs, and alerting to reduce MTTR and improve reliability in production environments.

FAQ: Hire .NET Developers
1. What core backend skills should a .NET developer have for enterprise projects?
Look for mastery in C#, ASP.NET Core, Entity Framework, SQL Server, and RESTful API design. Expect strong async programming, profiling with tools such as dotTrace or PerfView, and test driven development with xUnit or NUnit. Cloud experience with Azure App Services, Functions, and Docker supports scalable deployments and compliance needs.
2. How do you assess a developer's performance and debugging skills during hiring?
Use a timed coding task focused on backend logic and database access. Include a debugging exercise with a memory leak or deadlock scenario and require a written remediation plan. Review prior repositories and pull request histories. Request profiling artifacts and CI/CD examples. Score on code clarity, test coverage, and communication.
3. How do backend .NET developers handle performance and scalability issues?
Start with profiling to find hotspots using dotTrace, PerfView, or Application Insights. Replace per row database calls with bulk queries and tuned indexes. Fix memory leaks by disposing resources and removing lingering event handlers. Adopt async best practices, add caching, connection pooling, background queues, and configure autoscaling on Azure. Measure response time and resource use before and after each change.
4. How do .NET back end developers secure enterprise applications and sensitive data?
Apply defense in depth. Enforce strong authentication and role based authorization with OAuth2 and JWT. Use HTTPS and TLS across all endpoints. Encrypt sensitive fields and enable Transparent Data Encryption for SQL Server. Store secrets in Azure Key Vault or use managed identities. Run static analysis, dependency scans, pen tests, and log access for audits.
5. How do .NET teams integrate legacy systems and third-party services effectively?
Wrap legacy systems with stable API layers or adapters. Use message brokers like Azure Service Bus or RabbitMQ for asynchronous integration and resilience. Implement data transformation layers and schema versioning to avoid breaking changes. Add contract tests and sandbox environments. Roll out changes behind feature flags and monitor end to end flows and error rates.
