Retool Developer with API Integration Experience — Hospitality SaaS

I am building VenueChi, a hospitality operations intelligence platform using Retool and Supabase. I have already created an initial dashboard and database structure, but I need an experienced developer to review the existing work, improve the user experience and complete external software integrations.

The platform will combine data from POS, reservation, workforce management and accounting systems, including Ordermate, SevenRooms, Deputy and Xero.

Initial responsibilities:

* Audit the current Retool app, queries, workflows and Supabase structure
* Identify errors, security risks and scalability issues
* Improve the dashboard design and mobile responsiveness
* Verify calculations and data accuracy
* Build REST API, OAuth and webhook integrations
* Configure secure external customer access and venue-based permissions
* Set up a branded custom domain for the Retool app
* Provide testing documentation and a clear handover

Required experience:

* Strong Retool experience
* REST APIs, OAuth 2.0 and webhooks
* PostgreSQL/Supabase and SQL
* JavaScript
* External SaaS integrations
* Authentication and role-based permissions

Experience with POS, Xero, Deputy, SevenRooms or hospitality software is highly desirable.

Please include:

* Examples of Retool apps you have built
* Examples of APIs you have integrated
* Your hourly rate
* Your availability
* How you would audit an existing Retool project

The first engagement will be a paid 8–10 hour technical audit. Further integration and development work will follow if the audit is successful.
