I recently completed a high-throughput .NET 8 API project that synchronized legacy SQL databases with modern cloud services, ensuring zero data loss and sub-millisecond latency. I noticed you’re looking to bridge internal systems, and my background in building resilient, decoupled architectures using ASP.NET Core makes me a strong fit for this integration. I focus on creating APIs that are not just functional, but self-documenting, highly secure, and easy to scale as your internal infrastructure and data requirements evolve. My approach involves architecting the API layer using a Clean Architecture pattern to separate business logic from data access, ensuring long-term maintainability and easier unit testing. I will leverage Entity Framework Core for optimized data handling and integrate Swagger/OpenAPI for real-time documentation, which simplifies integration and stakeholder review. For system reliability, I plan to implement structured logging with Serilog and custom health check endpoints to monitor the connectivity between your internal systems. If these systems require asynchronous communication, I can implement a message broker like RabbitMQ or Azure Service Bus to ensure the main API remains responsive while processing data synchronization in the background. Could you clarify if the internal systems utilize RESTful interfaces or if we will be interacting directly with legacy databases or SOAP services? Do you have a preferred authentication protocol such as OAuth2 or an internal JWT solution already established for these connections? I’m available for a brief call or chat here to ensure our technical roadmaps are perfectly aligned. I look forward to discussing how we can build a robust middleware layer for your team.

@juanpablomacf

I reside in the USA and am willing to submit to and able to obtain a background evaluation/investigation as required. I have 8 years of experience building ASP.NET Core 8 APIs connecting to Oracle 19c with EF Core and Oracle Managed Data Access, including real-time SignalR integration for Angular SyncFusion UIs. You will receive: - RESTful API endpoints (JSON) supporting data retrieval and manipulation for your Angular UI - EF Core 8 data models mapped to Oracle 19c with relationship handling and query optimization - SignalR hub for real-time database change notifications - OpenAPI/Swagger documentation for SyncFusion integration - Connection resiliency, retry logic, and transaction management for Oracle Risks: EF Core with Oracle 19c does not support certain scaffolded schema changes automatically; I will use migration scripts with manual verification. Real-time updates require either database triggers with a polling service or Oracle Change Data Capture; I recommend SignalR with application-level cache invalidation unless you need true database-driven push. Question: Does your Oracle 19c database have any existing change tracking mechanism, or should I implement real-time updates via application logic? Approach: Build API layer in .NET 8 with repository pattern, DTOs for JSON serialization, JWT authentication, and integrated SignalR. Deploy with CI/CD pipeline. Timeline: 4 weeks. Rate: $2,500 fixed or hourly as preferred. Ready to start pending background approval.

@RavenDetector

Hi, I am Everett, and I build reliable .NET APIs that keep Oracle data and modern UIs in sync. Your goal is clear. You need a secure API layer for Oracle 19c and Angular that supports read and write operations, returns clean JSON, and handles real time updates without slowing the app down. I can build that with a maintainable .NET 8 service layer that fits your current stack. I would use EF Core with Oracle 19c where it makes sense, add focused repository and service layers, and expose well structured REST endpoints for your Angular UI. For real time updates, I can use SignalR or a similar push pattern depending on your data flow. I also pay close attention to validation, error handling, logging, and CI friendly delivery so the API is easy to test and maintain. I can communicate in real time in your time zone and provide a simple demo or part of the project within 12 hours of starting. Q1: Do you already have API endpoint definitions, or should I help design them? Q2: Which real time events need to be pushed to the Angular UI? Q3: Will I be working against an existing Oracle schema, or should database changes be included? Best regards, Daniel

The Oracle side is usually where these projects get tricky, especially when the API layer needs to stay clean across many services. I would set up .NET endpoints, connect to Oracle via a solid data layer, and wire CI/CD so deployments are smooth. Can start today, working base ready in 4 days. The bid reflects the description. Real numbers come after we walk through the full scope. Want to jump on a quick call?
