Custom web apps & REST APIs (ASP.NET Core)Selman Altinay
Business web applications, portals and REST APIs in C# / ASP.NET Core with SQL Server or PostgreSQL, deployed on Azure or Docker. Typical work: an internal tool that replaces spreadsheets, a customer portal, an API for a mobile app or partner, or new features and fixes in an existing .NET application.
Delivered examples: a modular web ERP, a GDPR/KVKK consent management platform and EveryTranslate, Rui Codex's own AI translation SaaS.
Packages (fixed price, USD):
Starter — $600, 5 days (about 8 hours of work): A small REST API (a few endpoints) or one feature or fix in an existing ASP.NET Core application, with tests where practical and a short technical note.
Standard — $1,800, 14 days (about 24 hours of work): One business module or API: authentication, a SQL Server or PostgreSQL data model, CRUD screens or endpoints, validation and deployment to Azure or Docker.
Advanced — $4,500, 30 days (about 60 hours of work): A web application or portal MVP: users and roles, several modules, admin panel, basic reporting, background jobs where needed, Docker or Azure deployment and documentation.
The price shown on this service is the Starter package. For Standard or Advanced, send a message with your scope and I will reply with a written plan and a matching offer.
How it works: a written plan first, then milestones on a test environment with written updates, testing and adjustments, and a hand-over of the documentation. I work async-first in writing. You get a licence to use the delivered software for your business; Rui Codex keeps the source code (a source-code buy-out can be quoted on request).
