# Hire a Supabase developer for your backend > A Supabase developer sets up the database, user logins and file storage behind your app. Hire one when your product needs accounts and saved data without building a server from scratch. Canonical: https://erdibuilds.app/hire/supabase Last updated: 2026-11-06 (November 6, 2026) ## What Supabase gives you Supabase bundles a Postgres (A widely used, reliable database that stores your data in tables.) database, sign-in, file storage and live updates in one service. It is open source, so you are not tied to a single company's format. Your data sits in a standard database that other tools can read. It fits [SaaS products](https://erdibuilds.app/build/saas), [web apps](https://erdibuilds.app/build/web-app) and [mobile apps](https://erdibuilds.app/build/mobile-app) with user accounts, plus [internal tools](https://erdibuilds.app/build/internal-tool) that need a real database. Frontend developers often pair it with [Next.js](https://erdibuilds.app/hire/nextjs), [React](https://erdibuilds.app/hire/react) or [React Native](https://erdibuilds.app/hire/react-native-expo). ## The thing to ask about first: security In Supabase the app can talk to the database directly. Safety then depends on Row Level Security (Rules inside the database that decide which rows each user may read or change. Supabase documents that a table the app can reach without these rules can be read and written by anyone with the project's public key.). A good Supabase developer sets these rules for every table and can explain them in plain words. - Do you turn on Row Level Security for every table, and how do you test the rules? - How do you design the tables so that the data model can grow? - How do you handle changes to the database over time, for example with migration files? - Where do server secrets live, and what stays out of the app? - How are backups and a staging copy handled? - Can you show a project where users only see their own data? ## Typical milestones For a new product, backend work often comes first so the screens have something to talk to. Each milestone is funded before work starts and runs 1, 2, 3, 4, 6 or 8 weeks. The weeks in this example are for illustration, and developers set the length of each milestone in their proposal. **Example plan for a Supabase backend** | | Work | Proof of delivery | | --- | --- | --- | | For example, weeks 1 to 2 | Data model, tables, sign in with email and social logins | Test users can sign up; the table design is documented | | For example, weeks 3 to 4 | Access rules, storage for files, first server functions | A test shows that one user cannot read another user's data | | For example, weeks 5 to 6 | Emails, scheduled jobs, connection to payments or other services | Each connection works in a test run | | For example, week 7 | Backups, monitoring, handover notes | You hold the project account and a written guide | Milestones are from 50 to 2,000 each in your project currency. > Create the Supabase project under your own account and invite the developer. Then the data and the bill stay with you. ## Matching for Supabase Developers mark Supabase as Expert in (Up to 6 technologies they know best.) or Also works with (A technology they use, but not their specialty.). Matching combines this with the project type, the help type, portfolio, budget fit and availability, giving a score from 0 to 100 with plain reasons. A developer needs at least 40 to apply. 80 or more earns a Top match badge, and proposals reach you sorted by score. ## Frequently asked questions ### Supabase or Firebase? Supabase uses a standard SQL database and is open source. [Firebase](https://erdibuilds.app/hire/firebase) is quick to start and strong for live data and notifications. See both pages and ask a developer for a recommendation for your case. ### Do I still need a separate server? Often not at first. Supabase has server functions for custom logic. Bigger logic may call for [Node.js](https://erdibuilds.app/hire/nodejs) or [Python](https://erdibuilds.app/hire/python). ### Can a Supabase developer review my existing project? Yes. A security review of tables and access rules is a good first step. See [advice or code review](https://erdibuilds.app/help/advice-review). ### My app was built with an AI tool and uses Supabase. Is that fine? It can be, but check the access rules. Read [finish your AI-built app](https://erdibuilds.app/help/finish-your-ai-built-app). ## Related - [Hire a Firebase developer for your app](https://erdibuilds.app/hire/firebase): Firebase gives apps logins, data and notifications fast.
