Hello. I'm a seasoned professional with over eight years of practical software development experience. I've worked on similar projects, developing robust and secure APIs for various clients. One of my recent projects involved building a comprehensive API system for managing user data, case records, and integrating external services, similar to what you're looking for. I successfully implemented features like user authentication with OTP, data processing from external APIs, and integrated payment gateways, which resulted in a smooth user experience and reliable backend performance. Here’s how I’ll approach your project: I’ll start by setting up the user registration and login APIs, implementing email verification and OTP features. Then, I’ll create the case data APIs, ensuring smooth merging of JSON data, server-side rendering, pagination, and sorting. I'll also focus on the file upload, data editing, and linking, followed by the integration with the ML API. For payment, I’ll integrate the CC Avenue gateway and implement the necessary payment master APIs. Finally, I’ll work closely with your frontend team for integration support and ensure the API endpoints are well-documented. I’m confident I can get these APIs up and running efficiently, and I want to become your trusted, long-term partner. I'd love to discuss how I can help you. Thank you, Tobias.

I can develop a secure and scalable backend with all the APIs you need, along with full support for your frontend team. This will include registration with email verification, login with OTP, and a complete user master. I’ll build a master table for case data by merging JSON outputs from your ML APIs, and provide server-side DataTable APIs with pagination, filtering, and sorting. Duplicate columns will be detected and flagged, while case data will support full CRUD operations, multiple file uploads, exception linking, and downloads (bulk or single) as ZIP folders. I’ll also integrate communication with your ML API for parsed data, and create APIs for statistics, graph generation, package management, and CC Avenue payment gateway. For the stack, I recommend Node.js (Express) or Python (FastAPI/Django REST), PostgreSQL/MySQL, JWT authentication, and cloud storage such as AWS S3. The MVP with user and case modules can be ready in 2–3 weeks, with the full build including files, statistics, and payments in 4–6 weeks. Post-launch, I’ll provide bug fixes, optimizations, and documentation so your frontend team can easily integrate. Could you confirm your preferred backend framework, whether you want files stored locally or on cloud, and if role-based access (admin/user) is required? Best regards, Ved Sharma
