Qasim was easy to work with and managed just fine with what were loose requirements initially but helped to get us where we needed to go.

Wow what a professional. I never thought I could find this type of talent on here. If I could I would try to hire him just for myself. Very grateful for the work that I have received. 10/10 experience.

My Portfolio
FAQ
Do you build custom enterprise web applications from scratch?
Yes. I build custom enterprise web applications using ASP.NET Core, C#, and modern .NET technologies. This includes full-stack applications, business systems, utility apps, and customer or staff portals.
How do you handle deployment and hosting?
I can deploy your application to Azure as part of the project, or provide deployment-ready code and documentation if you’re hosting it elsewhere.
Do you handle both front-end and backend development?
Yes. I handle both backend and front-end development, including ASP.NET Core, Web API, Angular, and React, depending on the project's requirements.
How do you make sure the final application meets my requirements?
I start with a clear written specification, so we agree on the scope before development begins. I then break the project into small, testable modules and share progress throughout development so you can review and provide early feedback.
How long will it take
The timeline depends on the scope and complexity of the project. After reviewing your requirements, I’ll provide a clear estimate and development plan.
How do you handle testing?
Testing is part of the development process. I build and review the application in small, testable modules so issues can be identified and addressed throughout development rather than only at the end.
Do you provide maintenance and support after delivery?
Yes. I can discuss ongoing maintenance, support, bug fixes, and future improvements based on your project requirements.
What documentation and handover do I get?
You receive the agreed source code and relevant documentation needed to understand, maintain, and deploy the application. I also make sure the handover is clear so the system can be supported after delivery.
Do I own the source code?
Yes. You receive the agreed source code for the application along with the relevant project documentation at delivery.
Do you sign an NDA?
Yes. I’m happy to sign a mutual NDA to protect confidential business, technical, and project information before development begins.
