FAQ
Why do I need to contact with you before ordering your gig?
There are a lot of factors that need to know before starting your project. Before starting a project, I need to be sure that all the pieces are in place and that I can deliver what you need.
What's included in a revision?
The revision will be provided only for the ordered issue/bug and plug extension. You can't ask to fix another fixation or add-on in revision.
What do I need to take into consideration before starting the project?
We will need your requirement details and your complete cooperation in order for us to achieve the best possible results for you.
Can you sign an NDA to protect my business idea?
Yes, I'm happy to sign a mutual Non-Disclosure Agreement before we begin. Your business idea, code, and data remain completely confidential. Please share the NDA with me before the project starts so we can review and sign it together.
Can you integrate AI features like ChatGPT or OpenAI into my web application?
Absolutely. I have hands-on experience integrating the OpenAI API, ChatGPT API, and other LLM-based features directly into ASP.NET Core and React applications. This includes AI chat interfaces, content generation, intelligent search, document summarization, and custom AI-powered workflows.
What technologies do you specialize in?
My core stack is React.js / Next.js on the frontend, ASP.NET Core with C# on the backend, and SQL Server for the database layer. I also work with Entity Framework, REST APIs, JWT authentication, Tailwind CSS, and cloud deployment on Azure & AWS. For AI integrations, OpenAI
Do I own the source code after delivery?
Yes — 100%. Once the project is delivered and payment is complete, you have full ownership of all source code, files, and assets. You can host it anywhere, modify it freely, or hire any developer to maintain it in the future. I don't keep any licensing claims on your code.
Do you offer post-launch support or ongoing maintenance?
Yes. After delivery, I offer ongoing maintenance and support through a separate project or monthly retainer arrangement. This can include bug fixes, feature updates, security patches, server monitoring, or AI model updates.
Can you provide references from previous clients?
Yes — you're welcome to request references from satisfied clients who have given permission to be contacted. You can also read 70+ verified reviews directly on my profile, which reflect real project outcomes across industries.
