FAQ
Do I need to provide API keys or account credentials?
For testing, we will use sandbox keys, staging environments, or guided setup sessions over screen-share to ensure your live keys remain 100% secure.
Can you build custom APIs from scratch?
Yes! I can develop custom backend REST APIs using Python (FastAPI/Flask) or Node.js tailored to your database structure.
What happens if an external API changes its structure in the future?
I write modular, well-documented code that makes future updates straightforward. I also offer ongoing maintenance packages if needed.
