Can you fix an existing Supabase project someone else set up?

Yes, that's the common case. Send us the repo and the symptom — broken RLS, auth that won't persist, storage leaking files, webhooks dropping events — and we trace it and fix it. We inherit codebases for a living and match your conventions. Everything ships as PRs you review and merge.

Are you an official Supabase partner?

No. We're an independent senior dev studio that builds on Supabase every day. We're not affiliated with or endorsed by Supabase. You get a specialist who knows Auth, Postgres, RLS, Storage, and Edge Functions, working directly in your repo.

Can you migrate us from Firebase or a custom Postgres onto Supabase?

Yes. We migrate schema and data, port auth users and rules to Supabase Auth and RLS, and stage the cutover so nothing freezes. The old system stays live as a fallback until the new one is proven, and you approve every step.

Do you need access to our Supabase account?

For the code, no. We work in your repository and ship PRs against your project. You keep ownership of the Supabase project, its keys, and its billing. We build everything around it and document what we changed.

Services - A senior Supabase consultant for Auth, Postgres, RLS & Storage

Supabase gets you to a working prototype fast, then the hard parts arrive: row level security that actually isolates tenants, auth that persists on the server, storage that doesn't leak private files, and Edge Functions that don't drop webhooks. We audit your existing Supabase project, fix Auth, Postgres, RLS, and Storage, migrate you off Firebase or a custom Postgres, and ship production-ready flows — as a Supabase consultant on a flat monthly subscription.

What a Supabase consultant covers

Seven areas, from Supabase Auth to handoff. Work them top to bottom on a fresh build, or drop the one you're stuck on at the top of your board.

Supabase Auth

Sign-in that holds up in production, not just the happy path in the docs.

Email/password, magic links, and OAuth providers wired end to end
Sessions, refresh, and server-side auth in Next.js or your framework
Multi-factor, password reset, and email confirmation flows

Postgres & RLS

Row level security that actually enforces tenant isolation, plus a schema that scales.

Audit and fix RLS policies so users only ever see their own rows
Schema design, indexes, and migrations that don't lock your table
Postgres functions, triggers, and views where they belong

Storage

File uploads, buckets, and access rules that don't leak private objects.

Public and private buckets with correct storage RLS policies
Signed URLs, resumable uploads, and image transforms
Direct-to-Storage uploads that don't route large files through your API

Edge Functions

Serverless Deno functions for webhooks, integrations, and background work.

Stripe and third-party webhooks with signature verification
Idempotent handlers so retries don't double-process events
Scheduled jobs and server-side work kept off the client

Migrations

Move onto Supabase from Firebase, Neon, RDS, or a custom Postgres box.

Migrate schema and data with a tested cutover and rollback path
Port Firebase Auth users and rules to Supabase Auth and RLS
Keep the old system live as a fallback until the new one is proven

Production hardening

Close the gaps that turn into incidents once real traffic and real data arrive.

Lock down RLS, service-role key usage, and exposed endpoints
Connection pooling, query tuning, backups, and restore drills
Realtime, rate limits, and observability so failures surface early

Handoff & maintenance

You own it afterward. No lock-in, no proprietary wrapper, nothing you can't read.

Every change ships as PRs to your repo that you review and merge
Migrations, policies, and setup documented so it doesn't drift
Keep us on tap for the next fix, or take it fully in-house

Common Supabase pitfalls

Pitfall	How to avoid it
RLS left off, or policies that don't isolate tenants	Audit every table, enable RLS, and test policies so users only read and write their own rows.
The service-role key shipped to the browser	Keep the service-role key server-only; use the anon key plus RLS on the client.
Storage buckets left public by default	Set private buckets with storage policies and hand out signed URLs where needed.
Webhooks in Edge Functions that drop or replay events	Verify signatures and make handlers idempotent with an event log.
Migrations run by hand, straight against production	Version migrations, test the cutover, and keep a rollback path before you flip.
No connection pooling under real load	Use the pooler for serverless, tune pool sizes, and add the missing indexes.

We build it. You keep the keys.

devkyn is code-only, and independent — not an official Supabase partner. We wire up Supabase Auth, Postgres, RLS, Storage, and Edge Functions in your repo and ship it as PRs you review and merge. Your Supabase project, its keys, and its billing stay yours.
