I will develop a secure, scalable, and production ready net core web API for your apps
Ilias C
About this gig
I will build a secure, scalable and production-ready .NET Core Web API for your SaaS, mobile app, internal business tool, or IoT platform.
This gig is ideal if you need more than a quick script. I design APIs with clean architecture, clear structure, database integration, authentication, role-based access, Swagger/OpenAPI documentation, and deployment-ready code.
I can help you with:
- New .NET Core API development
- SaaS MVP backend foundations
- Mobile app backends
- IoT data APIs
- SQL database integration
- JWT authentication and role-based access
- Azure-ready deployment structure
- Docker and CI/CD preparation
- Refactoring or improving existing APIs
Before starting, I will review your requirements and suggest the safest technical approach.
My goal is to deliver a backend that is maintainable, secure, and ready to grow with your business.

I am a senior .NET / Azure backend engineer with 20+ years of experience building secure, scalable, production-ready systems.
I specialize in .NET Core Web APIs, SaaS backends, Azure cloud architecture, SQL databases, microservices, Docker, CI/CD, and IoT telemetry platforms.
My background includes smart-city IoT solutions, MQTT data pipelines, Shopify integrations, and AI/LLM business applications.
I’m ideally suited for founders, agencies, and growing businesses seeking clean architecture, reliable code, clear communication, and scalable backends.
FAQ
Will you work on private repositories?
Yes, I can securely access your Git or Azure DevOps repo with read/write permissions as required.
Do you provide support after delivery?
Yes, limited support for 3 days after delivery; extended support available as a custom order.
Do you build APIs from scratch or improve existing ones?
I do both. I can design and build a new API from the ground up or review, refactor, and optimize an existing .NET Core API for better performance, scalability, and security.
Which technologies do you use?
I work with ASP.NET Core, Entity Framework, SQL-based databases, JWT authentication, Docker, and Azure cloud services. I follow clean architecture principles and production-grade coding standards.

Yes. I implement secure coding practices, input validation, authentication, and role-based access control. Security is built into the architecture, not added at the end.
Do you provide deployment support?
Yes. I can deploy your API to Azure and configure environments properly. CI/CD pipeline setup is also available as an extra.
Will I receive the source code?
Yes. You will receive full source code with clear structure and documentation.

Yes. Database integration is included in Standard and Premium packages. Schema design can be handled based on your requirements.
Do you offer documentation?
Yes. Swagger/OpenAPI documentation is included. Extended technical documentation can be provided as an extra.
