FAQ
What do you need from me to get started?
I usually need your project details, tech stack, access to the codebase or repository, and any API keys or platform credentials required for the integration.
Can you work on an existing project?
Yes. I can integrate authentication, Stripe, Firebase, or Supabase into an existing application or continue work on a project already in development.
How long will the project take?
Timeline depends on the scope. Small integrations may take less time, while full backend, payment, and authentication setups usually require a more detailed workflow.
Do you offer revisions or support after delivery?
Yes. I provide revisions based on the agreed scope and can also help with fixes, adjustments, or additional support if needed.
