Supabase Specialist for Real-Time Applications
I help product teams build Supabase backends that are secure, understandable, and ready for real users. The work spans PostgreSQL data modeling, authentication, Row Level Security, storage, server-side access, and real-time features. I can join at architecture stage or diagnose an existing application where permissions, sessions, or data flows have become difficult to trust.
Problems this engagement is built to solve
The scope starts from the product problem—not a prepackaged list of technologies.
- RLS policies are disabled, duplicated, or too permissive
- Client and server authentication behave differently
- The data model makes simple product changes risky
- Real-time subscriptions leak, duplicate, or show stale state
- Admin access is mixed into public application logic
- Storage and database permissions do not match the product roles
What you should leave with
- A data model aligned with product roles and workflows
- Explicit Row Level Security policies and server boundaries
- Reliable authentication and session behavior
- Purposeful real-time subscriptions with clean lifecycle handling
- Documented migrations and operational responsibilities
What the work includes
A focused engagement covers the decisions, implementation, and handoff needed to solve the problem cleanly.
Authentication and RLS
Implement or review sign-in, server access, protected operations, policies, and admin boundaries for the actual user roles.
Real-time product flows
Add subscriptions only where live state improves the product, with cleanup, authorization, and predictable UI behavior.
Migrations and handoff
Keep schema changes reviewable and document environment, policy, storage, and deployment decisions.
A clear path from diagnosis to delivery
You see what is being changed, why it matters, and how the result is verified.
- 01
Map roles and data
Start from who can read, create, update, and delete each product resource and why.
- 02
Design policies
Express ownership and team access in PostgreSQL and RLS instead of relying on hidden client conventions.
- 03
Connect Next.js
Use clear browser and server clients, protected operations, and cache boundaries appropriate to the route.
- 04
Verify
Test anonymous, authenticated, cross-user, admin, expired-session, and real-time edge cases.

Frequently asked questions
Practical answers before we define the project scope.
- Can you review existing Supabase Row Level Security policies?
- Yes. I can map the intended roles and ownership rules, review tables and policies, identify missing or overly broad access, and implement changes in a reviewable migration path.
- Do you build Supabase authentication for Next.js App Router?
- Yes. I can implement or repair authentication, server-side session checks, protected operations, and role-aware application behavior for modern Next.js projects.
- When should a product use Supabase Realtime?
- Realtime is useful when users benefit from immediate shared state, such as live voting, delivery status, collaboration, notifications, or operational dashboards. It should not replace normal fetching where live updates add no user value.
- Can you take a Supabase MVP to production?
- Yes. The work can include data-model cleanup, RLS, auth boundaries, migrations, indexes, storage policies, real-time lifecycle handling, and a production handoff based on the application's needs.
