You will get a Next.js and Supabase code audit for security, RLS, and performance
Project details
Get a practical technical review of an existing Next.js and Supabase application before bugs, security gaps or architectural shortcuts become expensive.
I will inspect the agreed parts of your codebase and Supabase setup, reproduce the main issue where possible, and deliver a prioritized report covering correctness, security, maintainability and the safest next milestones. The service is designed for existing products—not for estimating or designing an entire application from a one-line idea.
My production work includes multi-tenant SaaS, Supabase Row Level Security, authentication, Stripe and webhook integrations, admin dashboards and operational background jobs.

About Alexandru
Full-Stack SaaS Developer | Next.js, React Native & Supabase
Salonta, Romania - 4:30 am local time
My recent work includes a multi-tenant lead CRM with Meta Lead Ads, WhatsApp and Stripe integrations; a web-and-mobile service marketplace; a 12-language fleet compliance app; and a trilingual municipal platform with a custom content-management system.
I can help when you need to:
• finish or stabilize an existing Next.js or Supabase application
• add a dashboard, role-based workflow or multi-tenant architecture
• integrate Stripe, Meta, WhatsApp, email, webhooks or third-party APIs
• build or repair a React Native / Expo mobile app
• turn a manual business process into clear, maintainable software
I work in TypeScript across the product, from responsive UI and API routes to PostgreSQL schema design, Supabase Row Level Security, authentication, background jobs and deployment. I also bring SQL Server and PowerShell experience when a project involves database operations or infrastructure validation.
What you can expect:
• a short technical assessment before implementation
• a written scope and realistic milestones
• clear communication about risks and trade-offs
• testable increments instead of a long black-box build
• launch support and practical documentation
If you already have a codebase, send the stack, the current blocker and the outcome you need. I can start with a focused audit or a small paid milestone and recommend the safest next step.
Steps for completing your project
After purchasing the project, send requirements so Alexandru can start the project.
Delivery time starts when Alexandru receives requirements from you.
Alexandru works on your project following the steps below.
Revisions may occur after the delivery date.
Confirm scope and access
I confirm the selected package, application area, expected outcome, available evidence and safe repository or staging access.
Reproduce and map the workflow
I reproduce the blocker where possible and map the relevant Next.js, authentication, API and Supabase data flow.
