A cloud file storage and sharing web application built with ASP.NET Core, Entity Framework Core, and modern N-tier clean architecture.
I started programming around age 12 (back in 2012), building Flash games with ActionScript. Because I was so young at the time, I didn't know version control systems existed, and tragically most of those early childhood projects were lost over time when old hard drives degraded.
Later on, by age 18, I landed my first professional software engineering role at Uk. Soft - Evolution and began using Git daily. Naturally, all commercial client repositories from that chapter remain strictly private.
FileRabbit holds a special place in my journey: it became one of the key catalysts that prompted me to start publishing code publicly and actively contributing to open-source software.
During my freshman year at university in Dnipro, Ukraine, I competed in and won an all-Ukrainian inter-university programming olympiad. As a direct result of that victory, I was awarded a full scholarship to the intensive Apriorit .NET Engineering Course. FileRabbit was our capstone graduation project for the program.
While my talented course teammate Igor Strochikov (@SilverSiN98) spearheaded much of the backend business logic and repository layers, my focus was to breathe life and personality into the application:
- Designed the branding, visual style, and vector rabbit art assets (
rabbit.svg,clouds.svg, UI explorer graphics). - Built the interactive frontend interface, file explorer, upload UX, and responsive layouts.
- Integrated the frontend views with ASP.NET Core MVC and client-side viewmodels.
(Note: As of September 4, 2026, I am also preparing to publish several of my historical preserved projects).
The solution follows strict Separation of Concerns across distinct architectural layers:
- Presentation Layer (
FileRabbit.PL): ASP.NET Core MVC with Razor Views, authentication, and custom controllers. - Business Logic Layer (
FileRabbit.BLL): Service layer orchestrating file system operations, permissions, and security. - Data Access Layer (
FileRabbit.DAL): Entity Framework Core with Unit of Work and Repository patterns for database decoupling. - Infrastructure (
FileRabbit.Infrastructure): Contracts, domain abstractions, and dependency injection boundaries. - ViewModels (
FileRabbit.ViewModels): Strongly-typed data transfer objects and validation models. - Unit Tests (
FileRabbit.Tests): Comprehensive xUnit tests covering access verification, permissions, and folder hierarchies.
- 📁 Cloud File & Folder Management: Hierarchical directory creation, nested folders, and instant file uploads.
- 🔒 Granular Access Control: Public and private file sharing with permission-based viewing and editing.
- 👁️ File Previews: Built-in viewing experience for documents, media, and images.
- 🎨 Original Visual Design: Custom vector illustrations, warm UI accents, and thoughtful UX states.
