Über diesen Service
Did you build your React or Next.js web application using AI tools like Cursor, Lovable, Bolt.new, or v0, but are now struggling to deploy it securely?
One of the biggest security risks with AI-generated code is that it often hardcodes sensitive API keys (like OpenAI, Claude, or Stripe) directly into client-side React files, exposing them to anyone inspecting the browser.
I am an independent Full-Stack Engineer and Deployment Specialist. I will take your React/Next.js project, refactor your frontend code to hide your API keys behind secure server-side routes, and deploy your entire application to Vercel or Railway.
What I can do for you:
- Deploy static React/Vite or Next.js frontends to Vercel with custom domain mapping and SSL setup.
- Deploy full-stack Node.js/Express backends to Railway.
- Refactor your code to move sensitive API keys (OpenAI, Claude, Stripe) into secure Vercel/Railway Environment Variables (.env) so they never leak to the client's browser.
- Set up and run PostgreSQL/Supabase database schemas and execute initial migrations.
- Set up secure authentication (Supabase/Firebase/Clerk) and handle OAuth redirect configurations.

FAQ
Where should I host my app? Vercel or Railway?
Vercel is optimized for static frontends and serverless applications (like React, Vite, or Next.js), while Railway is designed for running persistent backend services (like Node.js/Express), databases (PostgreSQL, Redis), and background workers. I will recommend the best architecture based on your c
How do you secure my API keys (like OpenAI, Claude, or Stripe) from leaking?
I migrate all client-side API requests into secure, server-side route handlers (e.g., Next.js API Routes). This ensures that your sensitive keys are stored safely as Environment Variables on the server, completely hidden and inaccessible to anyone inspecting the browser console.
Do you need direct access to my hosting, GitHub, or database accounts?
Ideally, yes—developer or collaborator access to your GitHub, Vercel, or Railway dashboard makes the deployment fast and seamless. However, if you prefer not to share credentials, I can provide a comprehensive, step-by-step setup guide, or we can configure everything together over a secure, live scr
Will my custom domain and SSL certificate be set up and secure?
Yes, absolutely. I will configure your custom domain name by mapping the proper DNS records (A, CNAME, or TXT records) and ensure that free, automatic SSL (HTTPS) certificates are fully activated and secured.
Are you willing to sign a Non-Disclosure Agreement (NDA) before reviewing my code?
Yes, 100%. I respect project confidentiality and your intellectual property. I am fully willing to sign a Non-Disclosure Agreement (NDA) before you share any repository access or project details.
