FAQ
1️⃣ Can you build specialized multi-tenant systems?
Yes. I design robust full-stack applications from bare metal. I utilize React and TypeScript to engineer responsive frontends and backend logic, deployed cleanly on Vercel and cloud platforms. I am also expanding into enterprise Java structures for upcoming large-scale pipelines.
2️⃣What happens if my platform requires extra pages?
If your custom web application requires additional pages beyond the base package parameters, they can easily be added as a project extra. The standard baseline rate is +$50 per additional custom layout module, which adds +1 extra day to our production development timeline.
3️⃣ Who covers the cost of hosting and domains?
The client covers all deployment infrastructure fees. If you prefer a seamless hands-off experience, I will manage the complete setup, acquisition, and cloud mapping for you via secure billing. I also track your domain lifecycle, sending renewal alerts to ensure 100% uptime.
