FAQ
1. What exactly will you build for me?
I build fully functional frontend SPAs for any niche — business dashboards, finance trackers, health planners, and more — all in-browser, no backend required.
2. Is this a ready-made software or custom-built?
It is 100% custom-built from scratch to match your specific business processes, size, and requirements. Unlike off-the-shelf software, every feature is designed for how you work.
3. How is my data stored and secured?
The system uses your browser's secure local storage. All data stays on your device or computer. I can also implement backup/export features.
4. Can it work without an internet connection?
Yes. Its core feature is offline capability, however; requires internet for first time setup.
5. What hardware do I need to run the software?
You only need a computer with a browser (Chrome, Firefox, etc.).
6. Is my financial and customer data secure in the browser?
Yes. The application runs locally on your machine; your data is stored securely in your browser's storage and never sent to any external server unless you explicitly use a backup/export feature. This local-first approach is inherently more private than most cloud SaaS.
7. How involved do I need to be during development?
I require your input at key stages to ensure the system matches your vision: 1) Initial planning, 2) Design approval for the dashboard/invoice layout, 3) Final testing and feedback. Clear communication is the key to a perfect result.
