FAQ
Can I see samples of your previous projects?
Yes. You can find selected projects in my Fiverr portfolio and on my personal website (finkonory.com) where I showcase AI SaaS, fintech, and full-scale web platforms. If you'd like to see something specific related to your idea, just send me a message.
Is the app fully responsive?
Yes. All applications are fully responsive and optimized for desktop, tablet, and mobile devices.
Do you provide hosting?
I provide deployment setup (Vercel or VPS configuration), but hosting costs are paid separately by the client. You will need your own hosting account (Vercel, VPS, Supabase, etc.).
Do you build custom features?
Yes. Every project is custom-built based on your requirements. Complex features (advanced business logic, multi-role systems, large-scale platforms) may require a custom quote.
Will I own the source code?
Yes. After final delivery and payment, you receive full source code ownership.
What is not included in the packages?
Large-scale platforms (like marketplaces, Uber-like systems, complex AI products, or enterprise software) require a custom offer. Please contact me before ordering.
Do you offer support after delivery?
Yes. I provide support for fixes within the revision scope. Long-term maintenance can be arranged separately.
Should I contact you before ordering?
Yes, please. Send me your idea and requirements first. I’ll review them and confirm the best approach before we start.
