Scalable .NET React Data Portal

@nicrosoft

Hi there, I am an experienced Software Engineer with 9+ years of hands-on expertise in .NET, React, scalable architecture, and complex data-driven systems. I am confident I am the perfect fit for this project and can deliver a production-ready solution within 20 days. I will build a full-stack application using .NET Web API, React, and PostgreSQL, designed for high performance, scalability, and clean architecture. I will create optimized PostgreSQL schemas, relationships, and seed scripts, and handle all CSV imports and schema migrations. The API will be fully stateless, follow async patterns, include token-based authentication, role-based authorization (Admin/User/Guest), and complete Swagger documentation. On the frontend, I will develop 200+ responsive React screens with hooks, validation, dynamic tables, dashboards, and role-based UI rendering. All features will be cleanly integrated with Axios and optimized via code-splitting. Performance improvements will be applied using EF Core/Dapper with tuned queries. Delivery includes a Docker-compose environment, deployment guide, test credentials, and a complete handover ensuring all access control and API functionality works correctly. I follow best practices clean code, Git branching, modular design, debugging, and cloud-ready deployment (Azure/AWS). I work independently and deliver reliable, enterprise-grade solutions. Let’s discuss the details and get started. Best Regards, Malik

Hello, I can deliver your full-stack .NET + React + PostgreSQL application with a scalable, production-ready architecture that supports high concurrency, 5+ lakh transactions, and a large UI surface (200+ screens). My approach focuses on clean modular design, efficient data modeling, and performance-tuned APIs that remain maintainable over time. On the backend, I will design a robust PostgreSQL schema with proper relationships, indexing, and optimized queries (EF Core or Dapper). CSV imports, schema migrations, and seed scripts will be fully automated. The .NET REST API will be stateless, async-driven, secured with token-based authentication, and include role-based authorization for Admin/User/Guest. Complete Swagger documentation will be included. On the frontend, I’ll build a React application with hooks, reusable components, responsive tables, client-side validation, and dynamic UI rendering based on user roles. Code-splitting, form handling, and error boundaries will ensure smooth performance across 200+ screens. You’ll receive: • Production-ready API + React UI aligned with all role policies • Complete PostgreSQL schema & seed data • Docker-compose for one-command local setup • Clean Git branching with meaningful commits • Handover checklist + test credentials • Delivery before 31st December I’m ready to start immediately and can maintain full clarity on progress with structured milestones. Best regards, Amaan Khan P. CUBEMOONS PVT LTD.

As a seasoned full-stack developer, I'm well-versed in every aspect of your project's requirements and more. I have robust skills in .NET Web API, REST principles, and the entire React stack - including hooks and functional components. My experience includes large backend systems, efficient database management using SQL, and data handling with CSVs. Moreover, my understanding of scaling high-concurrency and concurrent web applications have yielded successful outcomes for my clients in the past. I'm deeply familiar with principles like code-splitting within React to optimize performance, handling large datasets, leveraging EF Core/Dapper for optimized queries to improve database efficiency. With my expertise packed into this freelance pitch, I'm more than confident that I can deliver exactly what you need: a scalable .NET React Data Portal that meets your functional requirements now and into the future.

@anter69

Hello, and thank you for reviewing my proposal. I’m exactly the full-stack engineer you’re looking for. My expertise spans .NET, PostgreSQL, REST APIs, React, Docker, and role-based auth. I can start immediately, and your time zone works perfectly for me. I previously built a production-grade .NET + React platform for a fintech client. My role covered backend API design, database modelling, and front-end integration. I implemented JWT authentication, granular role policies, and secure admin tooling. The biggest issue was handling heavy concurrent loads on transaction endpoints. I solved it by introducing async EF Core patterns, query tuning, and caching layers. This past project mirrors your needs: a scalable API, role-driven UI, and Dockerized stack. Both require clean stateless design, efficient data access, and clear deployment flow. Both also demand secure access control and a front-end that adapts by user role. With this experience, I can deliver your full solution on time and with production quality. I will provide documented APIs, robust React components, and reliable PostgreSQL scripts. Your one-command local environment and deployment guide will be ready as requested. Thank you again for considering my application.
