You will get Production-ready SaaS backend built with Next.js and Supabase
Project details
I build production-ready SaaS backends using Supabase and Next.js - the stack trusted by thousands of startups worldwide.
What sets this apart: I don't just set up a database. I design the entire backend architecture with security and scalability in mind from day one. Every project includes proper Row Level Security policies, optimized PostgreSQL schema, and clean API structure that won't need to be rewritten as you grow.
I've built multi-tenant platforms, marketplace backends with Stripe Connect, and AI-powered SaaS applications. I work with AI-assisted development tools (Cursor, Claude Code) which means faster delivery without cutting corners on quality.
You get full ownership of your Supabase project and GitHub repository, clean documented code, and a backend that's ready to scale.

My focus is projects where the backend needs to work from day one: clean database architecture, auth, API and payment integration without technical debt that slows you down 3 months later.
I work with founders and small teams building SaaS products, marketplace platforms and B2B tools.
What I build:
-Supabase & PostgreSQL architecture, RLS policies, migrations
-Auth systems: email/password, OAuth, magic link, SSO
-Stripe integration: subscriptions, one-time payments, Connect for marketplaces
-REST API development with Node.js
-Data modeling for multi-tenant SaaS
-Serverless functions and edge logic (Supabase Edge Functions, Vercel)
How I work:
I use AI-assisted development (Cursor, Claude Code) which means faster delivery without compromising on quality. MVP in days, not weeks.
Good fit if:
-You're building a SaaS from scratch and need a solid backend
-You have an existing frontend and need a backend to support it
-You need to migrate from Firebase or another BaaS solution to Supabase
