Hello, I can help with this project. I’m an IIT graduate with 21+ years of software engineering experience and currently working as a Principal Software Engineer at a major tech company. I have strong experience with .NET, C#, high-performance backend services, OCR pipelines, image processing, and thread-safe concurrent systems. I’ve worked with Tesseract integrations in .NET and understand the optimizations needed for low-latency OCR workloads. I can build a lightweight, self-hosted OCR service or DLL using .NET 6+ with: Thread-safe parallel processing Fast English-only Tesseract configuration Lightweight preprocessing for improved accuracy without adding noticeable latency Clean REST API or reusable library interface Demo project, documentation, and optimized configs The focus will be on keeping the service fast, reliable, easy to integrate, and production-ready. Would like to discuss further.

Hi, I have hands-on experience building high-performance OCR solutions in C# using Tesseract and .NET. I can deliver a thread-safe DLL or lightweight Web API that accepts Base64 images, performs optimized English OCR with minimal latency, and returns clean text results. The solution will include complete source code, documentation, a demo project, and performance tuning to help meet your 95% accuracy and sub-200ms response targets. Best regards,

Hello, I’m Karthik, a Senior .NET Developer with 15+ years of experience building high-performance enterprise applications, APIs, and document-processing solutions. I can develop a self-hosted OCR service in C# (.NET 6+) using Tesseract OCR with a clean REST API or reusable DLL interface. The solution will accept Base64-encoded images, perform lightweight preprocessing (grayscale, adaptive thresholding, noise reduction where required), and return recognized English text with minimal latency. Key Deliverables: ✔ Thread-safe .NET 6+ Web API or DLL ✔ Base64 image input and text output ✔ Optimized Tesseract configuration (English) ✔ Parallel request handling ✔ Well-documented source code and solution files ✔ Demo console application/unit test ✔ Build & deployment documentation ✔ Performance profiling and optimization support I have experience developing OCR, document processing, image analysis, and API integration solutions. To achieve the target accuracy and response time, I would use Tesseract engine pooling, memory-efficient image processing, and optimized tessdata configurations while keeping external dependencies minimal. I am confident in delivering a robust solution that integrates seamlessly with your existing .NET applications. Best Regards, Karthik 15+ Years Experience | C# | .NET 6/8 | Web API | OCR | Tesseract

I am confident I can meet your performance requirements and deliver a clean, well-documented architecture. I look forward to discussing how we can achieve your goals.

@ASSAMWEB

Greetings, I have read the project description I have been working on a similar project in recent time "OCR applications" I am interested in the work open a chat to discuss requirements in details.

@sf264

Hello, I will develop a small, self hosted OCR service in C# that will accept a Base64 encoded image and instantly return the recognised text. Tesseract will be the engine under the hood. I have a rich experience with Tesseract on .NET. Message me at your earliest convenience to discuss more details. Let's make it happen!, Fahad.

@nevorek

Good day. I did a similar project, but using "Managed-C++ + CLR". I can develop thread-safe DLL with demo app and test: as you need. > under 200 ms Depend on what machine you are use. At least, need machine with AVX-capable CPU. > 95 % accuracy I suspect it won't work on the first try, but we'll teach him.

@bitwiz

Hi, I have built highly optimized, thread-safe C# wrappers around Tesseract using native .NET Standard/.NET 6+ bindings, specifically tailored for sub-200ms processing in high-concurrency environments. For your baseline, I can implement lightweight Grayscale conversion and Otsu thresholding directly via memory streams to boost Tesseract's accuracy without incurring the disk I/O latency of external imaging libraries. I am ready to deliver the minimal Web API alongside the parallel-execution unit tests to ensure it seamlessly integrates into your existing infrastructure.

@mahads31

As a seasoned software developer with extensive experience in C# and .NET technologies, I'm confident that I am the perfect fit for your C# Tesseract OCR API project. My background also includes a deep understanding of C++ which will come in handy while working with Tesseract. Over the years, I've successfully built several custom software and system architectures that align perfectly with your project's needs. My expertise doesn't end with mere development; I also excel in systems optimization and automation. This means I will be adept at staying true to your lightweight processing requirements, ensuring impeccable results in the lowest possible time frame. Additionally, my familiarity with cloud infrastructure and deployment techniques means I can ensure thread-safe execution during parallel calls without compromising on performance. One area where I believe I could contribute greatly is in "quick image pre-processing" - boosting accuracy without adding significant latency. Since this factors heavily into your project's success, it's an area I'm excited to tackle head-on. All deliverables you've specified, starting with well-commented code and solution files to comprehensive documentation are second nature to me.

@kapilasl

Hello, I am senior developer. I already have experience with C# + OpenCV applications for some image processing requirements. I can make you required C# Tesseract Local OCR API. Please contact me via chat Thank You

@letswork92

I understand that you are looking for a precise and efficient OCR service in C# to integrate seamlessly into your existing .NET applications. The need for a lightweight, self-hosted solution that processes Base64-encoded images with minimal latency is critical for your workflow. With over 12 years of experience in full-stack development and automation, I have successfully implemented Tesseract-based solutions before. My approach will ensure that the service remains thread-safe, allowing multiple parallel requests without blocking. I can also implement quick image preprocessing strategies to enhance text recognition accuracy while keeping response times under 200 ms. Along with complete source code and clear documentation, I will provide a demo project illustrating the functionality you require. Could you share more about the specific types of images you plan to use? This will help me tailor the preprocessing methods effectively.

@enocki8

Hi There, I can build a high-performance, self-hosted OCR service in C# (.NET 6+) using Tesseract configured exclusively for English, optimized for low-latency text extraction from Base64-encoded images. The solution can be delivered either as a lightweight class library (DLL) or a minimal ASP.NET Web API, depending on how you plan to integrate it into your existing applications. My approach focuses on performance first: a thread-safe architecture with pooled Tesseract engine instances, efficient memory management, and minimal image preprocessing. Rather than expensive image transformations, I typically use lightweight grayscale conversion, adaptive thresholding when necessary, and image normalization only when it improves recognition accuracy. This keeps response times well within your target range while maintaining high OCR quality. Deliverables will include: • Complete source code and Visual Studio solution files • Fully documented public API or REST endpoint • Build and deployment instructions • NuGet dependency list • Demo console application and/or unit tests • Tesseract language data and configuration files • Performance and accuracy testing guidance I have experience building .NET services focused on throughput, concurrency, and image-processing workloads. I am comfortable profiling OCR pipelines and optimizing both accuracy and response times to meet strict performance requirements. Best regards, ENOCK ISABOKE
