You will get I will develop a professional ASP.NET Core Web API using Clean Architecture
Project details
Are you looking for a robust, scalable, and secure backend for your next web or mobile application? You are in the right place.
I specialize in building enterprise-grade RESTful APIs using ASP.NET Core and Clean Architecture. I don't just write code; I design systems that are easy to maintain, scale, and integrate seamlessly with any frontend application.
What you will get:
• Clean Architecture: Strict separation of concerns (Domain, Application, Infrastructure, Presentation) making your app scalable.
• Security First: Implementation of JWT (JSON Web Tokens) for secure authentication & authorization.
• Database Integration: Entity Framework Core with SQL Server.
• Clear Documentation: Interactive Swagger UI documentation so your frontend team can easily consume the endpoints.
• Best Practices: Implementation of Repository Pattern, Unit of Work, Dependency Injection, and global Exception Handling.
Whether you need a simple CRUD API or a custom backend with complex business logic, I am ready to deliver high-quality, production-ready code. Let's build a solid foundation for your application!

About Abdelrhman Hamdy Tawfic
.NET Full-Stack Developer | Specialized in Agentic AI & RAG Systems

What I enjoy most about development is solving problems and building systems that make people’s work easier and more organized. I always try to write clean, maintainable code and create applications that are not only functional, but also fast, responsive, secure, and easy to use.
Over the past few years, I have worked on multiple academic, freelance, and real-world projects where I handled both frontend and backend development. This helped me understand how to build complete systems from the database layer all the way to the user interface. I’m comfortable working on APIs, authentication systems, database design, dashboards, admin panels, responsive frontend interfaces, and scalable backend architectures.
On the backend side, I have experience developing secure and scalable applications using ASP.NET Core Web API, Entity Framework Core, LINQ, SQL Server, and authentication/authorization systems. I worked with concepts like layered architecture, repository pattern, dependency injection, clean architecture principles, caching concepts, and API integration. I also explored real-time communication using SignalR to improve user interaction and live updates inside applications.
On the frontend side, I enjoy creating modern and responsive user interfaces using Angular, React, JavaScript, HTML5, CSS3, Bootstrap, and Tailwind CSS. I pay close attention to responsiveness, performance, accessibility, clean UI implementation, and user experience to ensure applications work smoothly across different devices and screen sizes.
I also have experience working with REST APIs, third-party integrations, and dynamic frontend applications that consume external APIs and display real-time data in organized and interactive ways. I enjoy building data-driven applications and improving the way users interact with information and services online.
In addition to web development, I have been expanding my knowledge in modern AI technologies and AI-powered applications. I studied Generative AI concepts and worked with Semantic Kernel, LangChain, vector databases, embeddings, RAG (Retrieval-Augmented Generation), and AI integrations to build intelligent and scalable solutions. This helped me understand how modern AI systems can be integrated into real-world applications and APIs.
I’ve also worked in team environments using Git and GitHub for collaboration and version control. During my projects, I communicated with teammates, organized tasks, solved technical issues, reviewed implementations, and contributed to delivering projects successfully and on time. I believe good communication, teamwork, and professionalism are just as important as technical skills.
Some of the projects I worked on include:
• Leave Management System for managing employee and doctor vacations
• Educational Platform with API-based backend architecture
• eCommerce Web Applications
• Library Management System
• Pharmacy Desktop Application using C# and SQL Server
• AI-based Diabetes Detection System using Python and Machine Learning
• API-integrated frontend applications using external REST APIs
I am currently enrolled in a professional 9-month Full Stack .NET scholarship at Information Technology Institute (ITI), where I continue improving my expertise in backend development, frontend technologies, APIs, databases, software architecture, Unit Testing, TDD, and modern software engineering practices through intensive practical training and real-world projects.
In addition to technical skills, I always try to keep learning and improving myself. I enjoy exploring new technologies, best practices, software architecture concepts, performance optimization techniques, and modern development tools. I like challenges because they help me grow as a developer and improve my problem-solving and analytical thinking skills.
I’m someone who cares deeply about quality, details, communication, and delivering work professionally. Whether it’s fixing bugs, building APIs, designing databases, integrating AI services, or creating responsive frontend pages, I always aim to provide solutions that meet client needs and create real value.
