You will get Production ASP.NET Core Web API with Authentication & Azure Deployment
Project details
I build clean, scalable ASP.NET Core Web APIs that are designed for real-world use—not quick fixes that require rewriting later.
With 20+ years of experience in enterprise software development, I focus on delivering APIs that are structured, maintainable, and ready for production from day one. My approach emphasizes clean architecture, efficient data access, and secure, well-defined endpoints so your system can grow without becoming difficult to manage.
Each API is custom-built based on your specific requirements within a clearly defined scope. Whether you’re building a backend for a web or mobile app, integrating systems, or creating a foundation for a larger platform, I deliver solutions that are built to last.
Projects include clean source code, API documentation (Swagger), configuration setup, and deployment-ready output with instructions for Azure, AWS, or container-based environments.
If you’re looking for a reliable, long-term solution built the right way, this project is designed for you.

About John
Senior .NET Architect | Legacy Modernization | APIs | Azure | 25+ Year
Hartland, United States - 8:41 pm local time
With 25+ years of experience, I’ve worked with organizations like Northwestern Mutual, Milwaukee Tool, Royal Bank of Canada, Harley Davidson, BP, Summerfest, CIBC Bank and RSM to design and deliver mission-critical software systems.
Most of the clients I work with are dealing with:
Aging .NET applications that are difficult to maintain
Performance bottlenecks in SQL Server or APIs
Complex integrations between systems (APIs, ETL, third-party platforms)
I specialize in stepping into these environments, quickly understanding the architecture, and delivering clean, scalable solutions.
What I can help you with:
Legacy .NET modernization (.NET Framework → .NET Core / .NET 6+)
API design & high-performance backend systems
SQL Server optimization and data-heavy applications
ETL / data integration (including complex XML/JSON workflows)
Microservices & distributed system architecture
Azure / AWS cloud-based solutions
I don’t just write code—I help design systems that last.
