About this gig

Is your legacy .Net Framework 4.x app slowing you down? High licensing costs and inability to deploy to Linux/Docker are holding your business back.

I specialize in end-to-end modernization of enterprise .Net applications, upgrading your system for the speed and scalability of 2026.

Core Services: Framework Upgrade: Migrate .Net Framework 4.x or .net core 3.1+ to .Net 10+. Replace obsolete System.Web with modern ASP.NET Core. Database Migration: Switch from MS SQL Server to PostgreSQL. I handle schema conversion, data migration, rewrite for new ORM. Refactoring: Upgrade from EF6/ADO.NET to EF Core, optimized for Postgres.

Performance Boost: Integrate Redis caching, optimize queries, and implement async/await patterns. Cloud Readiness: Dockerize your app with docker-compose for seamless AWS/Azure/Linux deployment.

Benefits: Cut Costs: Eliminate expensive MS SQL licensing. Boost Speed: .Net 10 is up to 5x faster than legacy frameworks. Scale Up: Ready for Kubernetes and Microservices.

️ Important: Migration is complex. Please message me before ordering! I offer a Basic Audit Package to analyze your system and provide a fixed-price roadmap.
