Registration
Management App

A complete registration workflow, from browser forms to API endpoints and SQL Server persistence.

I built the registration and user-management endpoints, connected the data layer, and created the frontend that calls the API.

Inside the project

One workflow. Three responsibilities.

Start with the user flow.

HTML, CSS, and JavaScript forms let users register and interact with the application. The browser calls the API, so I can test the complete workflow.

HTML · CSS · JavaScript

Handle the request.

ASP.NET Core Web API endpoints handle registration and user-management workflows. API logic stays separate from frontend behavior and data handling.

C# · .NET · REST APIs

Keep the data connected.

SQL Server stores the registration data. CRUD operations connect the application's management flows to persistent records.

Looking for
A junior backend role
or an internship

I like working on what happens behind the interface.

My focus is C# and ASP.NET Core: building Web API endpoints, connecting them to SQL Server, validating input, and handling CRUD workflows.

I also write HTML, CSS, and JavaScript to put those APIs to use. Building both sides helps me test a complete user flow and understand how each part fits together.
