C# / .NET / ASP.NET Core

C#/.NET backend developer focused on practical Web APIs.

I am an Information Systems Engineering student building ASP.NET Core Web API projects with SQL Server, validation, CRUD workflows, and simple frontend interfaces for testing complete user flows.

About

Backend-focused C#/.NET developer.

I am an Information Systems Engineering student focused on backend development with C# and ASP.NET Core. My current project work centers on building Web API endpoints, connecting them to SQL Server, validating user input, and handling CRUD workflows.

I use HTML, CSS, and JavaScript when needed to build simple interfaces around my APIs, so I can test complete user flows instead of only isolated backend requests.

Registration Management App

Registration Management App welcome screen with login and sign-up options

ASP.NET Core Web API / C# / SQL Server / HTML / CSS / JavaScript

A full-stack registration and management application built with an ASP.NET Core Web API, SQL Server, and a vanilla HTML/CSS/JavaScript frontend. I built the backend endpoints for registration and management flows, connected the app to SQL-backed persistence, and created browser forms that communicate with the API.

  • Built Web API endpoints for registration and user-management workflows.
  • Stored and queried registration data with SQL Server-backed CRUD operations.
  • Added frontend forms that call the API and support the main user flow.
  • Kept frontend behavior, API logic, and data handling separated for maintainability.
