I will fix and deploy your lovable bolt replit or supabase app
Siyu Ren
About this gig
Is your Lovable, Bolt.new, Replit, Base44, v0, or Cursor app broken, failing to deploy, or stuck with Supabase, API, authentication, or database errors?
I help founders turn broken AI-built apps into working products. I diagnose the root cause, repair the code or configuration, test the result, and explain what changed.
What I can fix: Vercel, Netlify, or Render deployment failures React, Next.js, TypeScript, or Vite runtime issues Supabase Auth, RLS, PostgreSQL, and Edge Functions REST APIs, OAuth, Stripe, webhooks, and OpenAI API integrations Environment variables, redirects, domains, and GitHub deployment Node.js backend and database connection errors
You receive a root-cause diagnosis, tested fix, deployment check, and handover notes.
Before ordering, send the exact error, screenshot or log, expected result, app URL, stack, and repository availability. I will recommend the right package or a custom offer.
Each package covers the agreed issue or feature in one repository. Larger builds, redesigns, migrations, and multi-feature work require a custom offer.
Never send passwords, Secret Keys, service_role keys, database passwords, or payment information.

I help founders rescue and stabilize AI-built web apps and backend systems. I diagnose deployment failures, Supabase Auth/RLS problems, API and database bugs, and Spring Boot issues, then deliver tested fixes with clear handover notes. My stack includes Lovable, Bolt, Replit, React, Vite, Supabase, Vercel, Java, Spring Boot, REST APIs, PostgreSQL, MySQL, Redis, and n8n. With 8 years of backend experience, I focus on root-cause analysis, secure access, clear scope, and practical fixes without unnecessary rebuilding.

FAQ
What should I send before ordering?
Please send the exact error, a screenshot or build log, your expected and actual results, the app URL, technology stack, recent changes, and repository or ZIP availability. I will confirm the correct package before you order.
Do you need my passwords or Secret Keys?
No. Never send passwords, Secret Keys, service_role keys, database passwords, or payment information. You keep control of your accounts. I will provide steps for any owner-only actions.
What counts as one issue?
One issue is one reproducible failure with one agreed expected result, such as a failed Vercel build, broken Supabase login, or one database connection error.
Can you add features or improve my existing app?
Yes. I can repair or add clearly defined features, integrations, and deployment improvements. Send your requirements first, and I will recommend a package or custom offer for larger work.
Is every issue guaranteed to be fixed?
I review the evidence before ordering and only accept issues that fit the service. Third-party outages, unavailable source code, paid-plan restrictions, or owner-only settings may require buyer action. Any such limitation will be explained clearly.
What does a revision include?
A revision covers adjustments needed to resolve the original accepted issue. New features, unrelated errors, or changed requirements require a separate order.
Which platforms and technologies can you work with?
I can review Lovable, Bolt.new, Replit, Base44, v0, Cursor, React, Next.js, Vite, Node.js, Supabase, PostgreSQL, Vercel, Netlify, Render, REST API, OAuth, Stripe, webhook, and OpenAI API issues.
