Web Application Development

Modern web applications are no longer just a "website" — they have become the business systems that form the backbone of a company. ERP, CRM, order management, financial tracking, customer portals... all of this work now runs in the browser.

I design these kinds of applications from scratch or modernize existing systems. On the backend I use .NET (Web API, EF Core, MediatR), and on the frontend Angular or React/Next.js.

What kinds of projects do I build?

• Multi-user enterprise ERP / CRM systems
• B2B portals and order management systems
• Internal admin panels and management interfaces
• SaaS products (multi-tenant architecture)
• Customer-facing self-service platforms
• Reporting and dashboard systems

Technical preferences

• Backend: .NET 8, Web API, Clean Architecture, MediatR, FluentValidation
• Frontend: Angular 17+ or Next.js 15 (App Router)
• Database: SQL Server, PostgreSQL, EF Core 8
• Auth: ASP.NET Identity, JWT, OAuth2/OIDC
• Cache & queue: Redis, RabbitMQ
• Cloud: Hetzner server, Docker, containers
