I’m a .NET Developer focused on building scalable, reliable applications with C#, .NET 10, ASP.NET Core, MVC, Web APIs, and SQL Server. I prioritize clean, maintainable codebases and apply Clean Architecture and DDD fundamentals to keep systems well-structured and easy to evolve over time.

Before transitioning into software engineering, I led international IT and digital transformation initiatives across Europe. That experience strengthened my ability to translate operational requirements into practical technical solutions and collaborate effectively in cross-functional environments.

• Building ASP.NET Core MVC applications and RESTful Web APIs on .NET 10
• Designing SQL Server-backed systems with clear data workflows (LINQ, migrations)
• Applying Clean Architecture, Repository Pattern, Dependency Injection, and DDD fundamentals
• Writing testable, maintainable code (unit testing with xUnit and Moq)
• Working in structured, collaborative development environments (Git, GitHub, Jira, API tooling)

Backend API acting as a gateway to an external weather service, demonstrating secure API design, external service integration, and structured error handling.

Highlights

• Implemented JWT-based authentication and secured endpoints using [Authorize]
• Integrated external API via HttpClient with configurable base URL and timeout
• Applied DTO mapping to transform external responses into internal API models
• Built global exception handling middleware for consistent error responses (502/503/504)
• Used structured logging with ILogger for request tracking and diagnostics
• Designed clear separation between controller, service, and integration layers

RESTful Web API for managing movie data, paired with a separate ASP.NET Core MVC client that consumes the API through structured HTTP communication.

Highlights

• Designed and implemented REST endpoints supporting full CRUD operations
• Applied asynchronous request handling using async/await
• Implemented Data Transfer Objects (DTOs) to decouple API and client models
• Used the Repository Pattern to separate business logic from data access
• Enabled structured JSON request/response handling between API and client
• Added filtering and sorting logic for efficient data retrieval

Business-oriented invoice management system built using a Database-First approach, focusing on structured data handling, calculations, and clear presentation of financial records.

Highlights

• Reverse-engineered SQL Server schema using Entity Framework Core Database-First scaffolding
• Implemented invoice and line-item workflows with reliable totals calculation
• Used LINQ queries for filtering, aggregation, and summary views
• Built Razor-based UI for full CRUD operations and data presentation
• Extended scaffolded models using partial classes to preserve clean structure

Student and grade management application focused on relational data modeling, seeded datasets, and query-driven presentation logic.

Highlights

• Code-First domain modeling with Entity Framework Core migrations
• Seeded relational data (students, grades, subjects)
• LINQ-based filtering, grouping, and projection for reporting-style views
• Razor UI for structured data display and navigation
