What I’m Building
A production SaaS application to learn full-stack development end-to-end—from authentication to payments to deployment.
Core Features
Authentication: Supabase Auth with email/password and OAuth. JWT-based sessions with automatic refresh.
Multi-Tenancy: Row-level security (RLS) in PostgreSQL ensures users only see their own data. Each tenant is completely isolated.
CREATE POLICY tenant_isolation ON documents
USING (tenant_id = auth.uid());Payments: Stripe integration for subscriptions. Webhook handling for payment events, subscription changes, and failed payments.
AI Features: Document processing with OpenAI APIs. Using LangChain for structured data extraction from uploaded files.
Technical Stack
Frontend: Next.js 14 with App Router, TypeScript, Tailwind CSS. Server components for initial load, client components for interactivity.
Backend: Supabase for database (PostgreSQL), auth, and file storage. Edge functions for serverless API routes.
Infrastructure: Deployed on Vercel with automatic previews for PRs. Environment-based configuration for dev/staging/prod.
Key Learnings
- Row-level security is powerful but requires careful policy design
- Stripe webhooks need idempotency handling
- Server components reduce client-side JavaScript significantly
- TypeScript catches bugs before they reach production
Current Status
Actively developing. Core auth, database, and payment flows working. Building out AI features and refining the UI.
