About this gig
Base44 integration expert for Base44 Stripe integration, Base44 API integration, Base44 Supabase integration, Google login and webhooks, all connected and tested on your live app.
Your app looks finished but payments, logins or data won't connect? I wire it up so it works live, not just in preview.
PROBLEM AND FIX
Stripe checkout fails or payments never confirm? I set up the Stripe integration with webhooks and check it in test and live mode.
Google login or OAuth redirects break? I connect the auth and verify it on your live domain.
Data won't save or sync? I handle the Supabase integration with the right tables and access rules.
An outside tool or API returns errors? I build the API integration with request mapping and error handling.
Emails, forms or automations never fire? I connect email, webhooks and automations.
API keys exposed in your app? I move them into secure settings.
HOW IT WORKS
Send your app link and what you want connected. I confirm the scope and price before you order. Need 5+ integrations? Message me first for a custom offer.

Built your app with Lovable or Base44 and now it's stuck? I get it onto iPhone and Android and through app review.
I fix white screens, Supabase login errors and Capacitor iOS build problems, and I handle App Store and Google Play rejections: reading the reviewer's message, fixing what was flagged, and preparing a clean resubmission.
I also build AI-powered apps for founders and creators who want a real, store-ready mobile app.
Send me a screenshot or your rejection message and I'll point you to the quickest route to a working app.
FAQ
Can you do a Base44 Stripe integration?
Yes. I connect Stripe checkout, set up webhooks, and check the full payment flow in test and live mode. You provide your own Stripe account, and I never need your secret keys in chat.
Do you handle Supabase integration for Base44 apps?
Yes. I connect your app to Supabase, set up tables and access rules, and test that data saves and loads correctly. Send your app link and I’ll confirm the scope before you order.
Can you fix Google login and OAuth problems?
Yes. I connect Google sign-in, fix redirect errors and verify it works on your live domain, since login often works in preview and breaks after publishing.
Which APIs and tools can you connect to Base44?
Stripe, Supabase, email services, webhooks and most REST APIs. If you have a specific tool in mind, message me and I’ll confirm it can be connected before you order.
What counts as one integration?
One service connected and tested, such as Stripe checkout or Google login. Subscriptions, webhooks and customer portals count as extra parts, so Standard and Premium cover those.
Do I need my own accounts for Stripe and other services?
Yes. Stripe, Google Cloud and email accounts belong to you, so you keep control of your money and data. If you don’t have them yet, I’ll tell you what to set up.
How do you handle my API keys safely?
I never ask for secret keys in chat. You add them inside your app’s secure settings, and I use them from there. I also check that none are exposed in your front-end code.
How long does an integration take?
One integration takes about 2 days and a full setup up to 7. The time depends on how fast you set up your third-party accounts.
What if the integration doesn’t work after you finish?
I test it before delivery and fix any problem within your package’s revisions. If a third-party service changes or has an outage, I’ll tell you honestly what’s causing it.
Can you also fix other bugs in my app?
Yes. Integration problems often come with other errors. Small related fixes are fine. For bigger issues, I’ll quote a custom offer
