Personal Portfolio Microservices Platform

Personal Portfolio Platform is a production-ready, enterprise-grade backend system built using modern .NET technologies and a distributed microservices architecture. It provides a comprehensive solution for managing and presenting portfolio content in a scalable, modular, and maintainable way. The system is designed with a strong focus on clean architecture principles and real-world software practices. Each service is responsible for a specific domain, enabling independent development, deployment, and scaling. This structure ensures flexibility and allows the system to evolve without impacting other components. At the core of the platform is an API Gateway implemented with YARP (Yet Another Reverse Proxy). It handles routing, request forwarding, and centralized communication between services, acting as a single entry point that improves security and system organization. Authentication and authorization are implemented using JWT (JSON Web Token), ensuring secure access across all services. Only authenticated users can perform sensitive operations such as managing content, uploading files, or accessing administrative features. The platform includes multiple independent services: • Gateway Service for routing and request handling • Auth Service for authentication and token management • Website Service for portfolio logic such as projects and skills • File Storage Service for handling file uploads and downloads • File Metadata Service for managing file-related data • Notification Service for handling email-based notifications Each service uses its own database to ensure data isolation and scalability. PostgreSQL is used as the primary database system, with Entity Framework Core handling data access and migrations. The system follows the CQRS pattern using MediatR, providing a clear separation between read and write operations. This improves code structure, maintainability, and testability. The application is fully containerized using Docker and orchestrated with Docker Compose, allowing consistent environments and easy deployment. Services can run independently while maintaining communication within the system. Logging is implemented with Serilog, enabling structured logging and better observability. The system also includes proper error handling, validation, and performance considerations. On the frontend, ASP.NET Core MVC is used to build both a public portfolio website and an admin panel. The admin panel allows dynamic management of projects, skills, certificates, and user data. Key features: • Microservices architecture with domain separation • API Gateway using YARP • Secure authentication with JWT • Clean Architecture with CQRS and MediatR • Independent PostgreSQL databases • Dockerized deployment • Structured logging with Serilog • File management system (upload, download, metadata) • Dynamic admin panel • Modular and extensible backend design This project demonstrates advanced backend development skills, including microservices architecture, API gateway design, authentication strategies, and distributed systems. It reflects real-world development practices and showcases the ability to build scalable and maintainable systems. Personal Portfolio Platform is not only a portfolio project but also a strong representation of enterprise-level backend architecture and modern .NET development.
