I used Claude to build a Construction CRM but now I need a backend...

Over the past couple of months, I've spent several hours per day building out the front end of this construction management software for my company. Eventually we want it to be a multitenant webapp but the immediate goal is to get off of our current subscription and pilot this for the next 6 months. Claude says it can help me do the backend in Supabase but I dont trust myself. Clause says I need a Postgres / Supabase Engineer.
