Aldian Fazrihady adalah Programmer Freelance Senior, Full Stack Developer, dan AI Application Engineer (Profil Upwork | Direktori Lengkap 415+ Panduan Programmer Freelance).
Supabase has become the premier managed PostgreSQL platform for modern SaaS and AI applications—combining a dedicated Postgres database, pgvector semantic search, Supavisor connection pooling, Row-Level Security (RLS), and Realtime subscriptions.
If you want to hire a freelance Supabase, PostgreSQL RLS, and pgvector full stack programmer across Next.js, React, and Python (Django/FastAPI), I am Aldian Fazrihady.
Production Supabase & PostgreSQL Engineering
1. High-Performance Row-Level Security (RLS) Policies
Naive RLS policies that call unindexed subqueries on every row scan degrade query performance by 100x. I write `(select auth.uid())`-cached RLS policies backed by composite tenant indexes and verify every permission boundary with automated pgTAP / pytest suites.
2. Hybrid pgvector + Full-Text Search (FTS) RAG Pipelines
I combine HNSW `pgvector` cosine similarity indexes with PostgreSQL `tsvector` BM25 keyword search inside a single Reciprocal Rank Fusion (RRF) SQL query (Production RAG Architecture with pgvector)—eliminating the cost and sync complexity of a separate vector database.
3. Supavisor Transaction Pooling with Django & Cloud Run
This very website runs on Google Cloud Run backed by Supabase PostgreSQL (Migrating Django Channels & React PWA to Cloud Run + Supabase).
