You will get your Legacy Database migrated to .NET Core and SQL Server


Project details
Stop letting legacy database limitations hold your business back. I specialize in migrating outdated data structures (Access, MySQL, older SQL Server versions) into modern, high-performance SQL Server environments integrated with .NET Core.
My approach ensures zero data loss, optimized indexing for faster queries, and a clean Entity Framework Core implementation that makes your application easier to maintain. Whether you are moving to Azure or keeping things on-premise, I provide a seamless transition with minimal downtime and full data integrity validation. Let’s modernize your backend today.

About Matthew
Senior .NET Architect | Legacy Modernization & High-Value QA
Arlington Heights, United States - 5:37 am local time
I don’t just write code; I protect and modernize the systems that run your business.
With 20+ years of experience—including founding and scaling a payment gateway to an eight-figure exit—I understand the high stakes of enterprise software. I specialize in the "impossible" projects: rescuing mission-critical data from legacy silos and architecting modern, cloud-native futures.
How I Help Your Business:
Legacy Rescue & Modernization: I am one of the few experts who can navigate 4D, MS Access, and FileMaker, providing a safe, zero-data-loss migration path to .NET Core/SQL Server.
System Architecture: I design scalable, secure systems for high-volume environments (Fiserv-level transaction standards).
Fractional CTO & Project Leadership: I bridge the gap between business goals and technical execution, ensuring your roadmap is realistic and your ROI is clear.
Obsessive QA: My background in high-stakes FinTech means "good enough" isn't in my vocabulary. Every deployment is backed by rigorous testing and a "Quality-First" mentality.
Core Technical Arsenal:
Modern: .NET Core/Framework, C#, ASP.NET MVC, SQL Server, Azure/AWS.
Legacy: 4D (4th Dimension), MS Access, Claris FileMaker, VB.NET.
Focus: API Integration, Database Optimization, and Enterprise System Design.
Whether you need to stabilize a 20-year-old database or architect a new SaaS platform from the ground up, I bring the experience of a founder and the precision of a senior engineer.
Let's discuss your system’s future.

Delivery time starts when Matthew receives requirements from you.
Matthew works on your project following the steps below.
Revisions may occur after the delivery date.
Assessment & Mapping
I will analyze your legacy schema and map data types to SQL Server equivalents, identifying potential compatibility issues or "breaking changes" early.
Environment & EF Core Setup
I'll set up the SQL Server instance and initialize the .NET Core project using Entity Framework Core (Database-First or Code-First) for seamless data access.
