Supabase systems
that don't break
when realtime
and RLS scale.
I'm Kavya - I design production Supabase systems across Postgres, Auth, RLS, Realtime, and Edge Functions. Your data stays consistent, secure, and fast under real-world load.
Real results. Real data.
Every Supabase system I build is measured by security correctness, realtime delivery, and time-to-fix.
SG Freight Pvt Ltd
Built SG Freight's production backend on Supabase — Postgres as the system of record for shipments, vendors, and money-flow state; Auth + RLS so each vendor only sees their own data; and Realtime so ops dashboards update as imports, exports, and payouts move. The same platform has processed $3.7M+ in revenue, with peak monthly volume hitting $400K. I've continued as their ongoing consultant for 4 years, extending schema, policies, and realtime feeds as corridors grow.
- •Modeled freight, vendor, and payout data in Postgres with lock-aware migrations
- •Hardened Supabase Auth + RLS so 120+ vendors stay tenant-isolated across US, Mexico, Canada, and LATAM
- •Realtime shipment and payout feeds replaced spreadsheet-based ops updates
- •Edge Functions + webhooks keep payment events and ledger state in sync with Supabase tables
At Your Service Psychiatry
At Your Service Psychiatry runs its appointments on Acuity Scheduling, with Supabase as the backend. I built the integration that keeps Acuity, Supabase, and Stripe Connect in sync, so every booked appointment triggers its own split: 80% to the provider who takes the session, 20% to the platform. Nobody reconciles payouts by hand. The system now handles around $45K a month, more than $600K a year.
- •Every Acuity booking kept in sync with Supabase and Stripe Connect
- •80/20 provider and platform split applied automatically on each appointment

What our client are saying about us
We brought Kavya in to take over our multi-tenant portal after another developer had started it, and he took it all the way to a complete, production-ready platform that now runs a big part of our day-to-day operations.
He set it up so each of our 120+ vendors across 8 countries works in their own space with the right access, while we manage everything from one place. He also built the Stripe Connect payments, which have processed over $3.7M so far, along with automation that now handles 850+ imports and 620+ exports every month and shipment alerts that keep everyone updated along the way.
What stood out most is that he doesn't just take a task and build it. He thinks it through first, flags anything that could cause problems later, and comes back with suggestions that often made the product better than what we originally asked for. We never had to hand-hold him—he understood the freight side of our business quickly and took real ownership of the work.
I'd recommend him to anyone building a serious product.

How Supabase integration normally works
A quick overview from Kavya — watch to see how Postgres, Auth, RLS, Realtime, and Edge Functions fit together in a production-ready stack.
// the_pattern
Supabase works on day one. Then RLS and realtime get real.
Auth works, queries run, and UI renders - but security boundaries, realtime fanout, migrations, and session edge cases quietly fail. Incident overhead compounds. These are the patterns I see most often:
RLS misconfig - authorized users can't access data
Impact: Blocked users and support ticketsRealtime fanout bottlenecks - updates arrive late
Impact: Stale UISession edge cases - token refresh loops
Impact: Users logged out mid-sessionMigration downtime - locks block critical tables
Impact: Build-to-prod delaysQuery regressions - N+1 patterns slip into production
Impact: Slow pages under loadEdge function timeouts - long tasks need queues
Impact: Async backlog growth// process
How I Build Production-Ready Supabase Systems
A methodical, Supabase-native approach to shipping safely across Postgres, Auth, RLS, Realtime, and Edge Functions.
RLS Contracts + Data Model First
Define Postgres schema, ownership rules, and RLS policies before writing features. Supabase becomes the system of record.
Auth Sessions + Tenant Isolation
Harden sign-in flows, token refresh, and multi-tenant boundaries. No session drift, no privilege surprises.
Realtime Delivery + Migration Safety
Make realtime reliable under load and ship migrations without blocking. Releases stay fast, reversible, and observable.
Supabase architecture components
Building blocks I use to deliver stable Supabase systems: RLS, auth sessions, realtime delivery, and migration safety.
RLS Policy Toolkit
Structured policy design, ownership mapping, and automated policy tests.
Auth Session Orchestrator
Hardened OAuth flows, token refresh behavior, and tenant boundary validation.
Realtime Event Router
Ordered subscriptions, fanout tuning, and backpressure-safe delivery.
Realtime + Cache Consistency
Consistency layers to avoid stale UI and cross-table mismatch.
Edge Functions with Queues
Queue-backed edge workflows to prevent timeouts and retries storms.
Migration & Drift Control
Lock-aware migrations, observability hooks, and rollback drills.
Questions I'll ask about your Supabase setup
So we can quickly identify where to focus and how to help.
How are you designing RLS for your roles and tenants?
A clear ownership model prevents privilege gaps and “it works locally” security issues.
How do you handle auth token refresh and session edge cases?
Session correctness determines whether realtime feels instant or breaks under load.
How are you scaling realtime subscriptions and event delivery?
Fanout, ordering, and backpressure rules decide whether users see updates reliably.
How do you run migrations without blocking critical tables?
Lock-aware rollout keeps uptime stable and prevents migration-induced downtime.
