Hello, Volodymyr! Creating integrations is my specialty, and your task is of great interest. I have experience in developing plugins in C#, including REST and SOAP integrations. I always prioritize quality, ensuring stability and secure data exchange. With my experience in idempotency/retries, your plugin will flawlessly handle errors. I look forward to the opportunity to discuss the details and start collaborating to successfully implement your project.

Good day.
I have practical experience in development with C#/.NET and integration solutions. I have worked with REST APIs, asynchronous event processing, logging, and error handling. I understand the approach to request idempotency and retries for stable integration with external systems.
I am ready to implement a plugin for data exchange between your system and Oracle POS, taking into account stability, logging, and error control.
I can familiarize myself with the technical details and specifications in personal correspondence. I am ready to discuss the scope, deadlines, and format of collaboration.

Good evening, I have already had experience working with Oracle. The price and deadlines are approximate, I would like to take a closer look at your task.

Hello.
I have significant experience in developing C#/.NET integration plugins that reliably exchange data with external POS and ERP systems, including REST/SOAP APIs, event-driven streams, and background services. For this project, I will develop a clean integration layer with clear data contracts, idempotent processing, retry logic, and structured logging to ensure stable and predictable synchronization with Oracle POS. I focus on resilience and observability so that errors are handled correctly and can be quickly diagnosed without impacting POS operations. Once the specifications are provided, I will be able to align the implementation precisely with Oracle's integration requirements and create a supported and ready-to-use plugin.

Hello! I am interested in your project.
I am a C#/.NET developer with a background in C++, so I specialize in creating stable, fault-tolerant systems, which is critical for working with POS.
Here is how I will approach the implementation of your plugin:
Architecture: I will implement a clear layer of abstraction for communication with the Oracle API.
Reliability: — I will use the Polly library to implement Retry policies (retries on network failures) and Circuit Breaker (protection against overload). — I will ensure the idempotency of requests through unique transaction identifiers (UUID/Guid) to avoid data duplication in case of communication issues.
Logging: I will integrate structured logging (Serilog/NLog) with logging of request/response bodies so that any error can be quickly debugged without stopping the cash register.
Formats: I have experience working with both REST (JSON) and SOAP (XML), which is often encountered in Oracle products.
I am ready to review the API documentation and start working.
