FAQ
Which package should I choose?
Basic is for a single landing page. Standard is for business apps that need login, a database and an admin panel. Premium is for complete platforms with dashboards, payments and integrations. Not sure? Message me and I'll recommend the right one.
Do I get the full source code?
Yes. Every package includes the complete source code, so you own your project 100%. I can deliver it as a ZIP file or push it to your GitHub repository.
Can you work on my existing project?
Yes. I can add new features, fix bugs, improve performance or migrate your project to a modern stack. Send me the details or the repository and I'll review it before giving you a quote.
Do you deploy the website?
Yes. I can deploy to Vercel, AWS, a VPS or your preferred hosting. The hosting and domain costs are paid by you, but I handle the full setup and configuration.
Can you add AI features or automation?
Yes, this is one of my specialties. I build AI chatbots, AI agents (MCP) and automations that save hours of manual work, like processing invoices or answering customers. Check the Gig Extras or message me.
What do you need from me to start?
A short description of your project, examples of websites you like, and your content (text, logo, images). If you don't have everything ready, no problem: we can define it together.
