I build web applications where customers manage their accounts, staff work through admin dashboards, and access depends on user roles or subscriptions. On Helpmarket, a .NET/React marketplace, I combined technical leadership with development contributions to authentication, subscriptions, wallet functionality, search, and paid promotion.

You can hire me to launch an MVP or add functionality to an existing product. Your application can include payments, search, customer portals, internal workflows, and integrations with the tools your business already uses.

What’s included:

Agreed feature scope, user workflows, and access permissions

Frontend development with React or Next.js

Backend APIs and database development with .NET and PostgreSQL

Payments, subscriptions, and external integrations where agreed

Automated tests for agreed business behavior

Source code, database migrations, API documentation, and deployment configuration

A technical handover explaining how to run and maintain the application

Before development, we’ll define what each user should be able to do and how we’ll verify that the functionality works. If you have an existing application, I’ll review the relevant code and integrations to scope the changes.

Send me a short description of your product, who will use it, and the main workflow you need to build or improve. Include designs, requirements, or existing code if available—you don’t need a finished specification to start the conversation.
