Ongoing collaborationThe seller handled the project very well and took time to understand the existing setup before making changes. The app is much more stable now, especially the login, dashboard, form, and Supabase connection. I also liked that my existing structure and data were kept safe instead of rebuilding everything. Clear communication and solid work throughout.

Ongoing collaborationThe project was in a pretty messy state after changes from different AI builders, but the debugging was handled carefully. What stood out most was that the existing setup was preserved instead of trying to rebuild everything. The form, Supabase data flow, and account separation are working much better now, and each change was explained clearly.
