Very happy with the work. I had a notification issue in my BASE44 app and some alerts were not sending correctly. He quickly found the problem in the workflow and explained how to fix it step by step. After applying the changes, everything works perfectly. Highly recommend for BASE44 fixing, workflow issues, and notification problems.

John did an excellent job reviewing my restaurant ordering app. He quickly identified the workflow issues and gave clear step by step fixes. His advice was practical and easy to follow. Highly recommend for anyone using BASE44 who wants a reliable workflow review, bug fix, or app troubleshooting.

Absolutely amazing work! He fixed all the office data isolation issues in my PulseOS app, making sure each office only sees their own data while admins have full access. He also integrated Stripe payments with 3 subscription plans (Starter, Pro, Elite) including add-ons, webhooks, and feature gating...
