À propos de ce service

Is your Next.js or Supabase app failing in auth, API calls, forms, data access, or deployment?


I diagnose and fix defined issues in existing Next.js, React, TypeScript, and Supabase applications.


This Gig can cover:

  • runtime and TypeScript errors
  • Supabase auth and session problems
  • API routes and external API connections
  • database queries and affected RLS policies
  • forms, CRUD flows, tables, and filters
  • responsive UI issues
  • deployment and environment configuration


I have delivered production web platforms with authentication, databases, dashboards, admin workflows, payments, APIs, and multi-language interfaces.


Before ordering:


Send a reproducible issue, expected behavior, screenshots, logs, and repository context before ordering. I will confirm whether it fits a package.


New pages, major redesigns, migrations, payment systems, broad security audits, or full SaaS builds require a custom offer. I do not guarantee that unrelated issues in an existing codebase will be resolved by one order.
