The goal is to deliver a custom-built web application where users can drop a photo of a coin and instantly receive a clean, background-free PNG ready for catalogues, auctions, or grading. All code should be written from scratch—no WordPress, Shopify, or other off-the-shelf frameworks—so the interface and processing pipeline stay lightweight and fully under my control. Core flow 1. Upload: drag-and-drop or file-picker for high-resolution coin images (JPG, PNG, TIFF). 2. Processing: server-side background removal that preserves coin edges and metallic luster; an AI model (e.g., U-Net, DeepLab, or your own OpenCV pipeline) is welcome if it maintains crisp rims and avoids haloing. 3. Preview & Download: present a low-res preview for quick confirmation, then allow download of the full-resolution transparent PNG. Deliverables • Responsive single-page web interface (HTML5, CSS3, vanilla JS or modern framework of your choice). • Background-removal microservice with documented code, install scripts, and model weights (if ML is used). • REST or GraphQL endpoint to accept future expansion (such as batch processing or user accounts). • Clear setup guide and minimal hosting requirements so I can deploy on a standard Linux VPS. Acceptance criteria – Image upload succeeds for files up to 25 MB. – Transparent PNG output keeps >98 % of coin edge pixels intact (visual inspection). – Round-trip from upload to download stays under 8 seconds for a 3000 × 3000 image on a 4-core server. Optional but appreciated: hooks for adding authentication and credit-based usage later. Please focus on writing clean, maintainable code and document any external libraries or models used.

I understand that for your project, a custom-built web application is essential, and I'm prepared to deliver exactly that. With my 20+ years of experience in building complex software systems, including my tenure at Cisco Systems and Qualcomm, I feel well-equipped to tackle every aspect of this project. From designing a robust and responsive single-page interface (using skills like Flask, JavaScript, HTML) to developing a server-side background removal feature with an AI model (deep learning libraries like TensorFlow or PyTorch) while avoiding artifacts on coin edges, I have the necessary expertise. Moreover, I've always strived to build systems that last and solve complex engineering problems effectively. I'm not just about implementing features but providing long-term solutions. Creating a system with clean codes, minimal hosting requirements in your standard Linux VPS that can accept potential expansion like batch processing or user accounts via REST or GraphQl endpoints is definitely something I can deliver. Let's talk further about how we can actualize your vision!

Hi there, I got it. And in this coin edge preservation and image-processing accuracy will be the most crucial part, because removing the background is easy, but maintaining the coin rims, metallic details, and avoiding halos is what makes the output production-ready. Therefore, I will start with the processing pipeline first, test a few sample coin images, and identify the best approach between AI-based segmentation and OpenCV-assisted edge refinement to ensure clean transparent PNG outputs. And then I will build the upload workflow, preview system, download functionality, and a lightweight API layer so future features like batch processing, authentication, or credit-based usage can be added without major changes. For performance, I will optimize the image-processing flow to keep upload-to-download times within your target range while maintaining output quality. I would request you to share a few sample coin images so I can validate the approach and discuss the architecture before finalizing the timeline and budget. Thanks, Rahul A.

Hi, Thank you for posting the good task! As a fan of building custom web applications and AI-powered processing solutions, my main skills are JavaScript, modern frontend frameworks, backend development, image processing, API design, and automation workflows, so I have strong experience creating lightweight applications with custom pipelines instead of relying on heavy platforms. Plus, the fact that your project requires a dedicated coin image processing system with upload handling, AI/OpenCV-based background removal, preview generation, and transparent PNG output aligns directly with my recent work. By analysing the image quality requirements and processing flow carefully, I will ensure the application delivers clean results while keeping the architecture scalable for future features. I have some questions: 1. Do you already have a preferred AI model or would you like me to evaluate the best approach between OpenCV and ML-based segmentation? 2. Will the application need GPU support on the VPS, or should it be optimized for CPU-only deployment? I have a deep understanding of custom web applications, image processing workflows, REST APIs, performance optimization, and clean backend architecture. I always focus on maintainable code, clear documentation, and building solutions that can grow with future requirements such as user accounts and credit systems. Looking forward to working with you for the long term. Best regards, Diah
