FAQ
What technologies do you use?
I specialize in Next.js, React, Node.js, TypeScript, and Tailwind CSS, backed by PostgreSQL, Supabase, or MongoDB. For AI SaaS features, I integrate OpenAI, Claude, and custom LLM APIs, recommending the best stack for your project.
Do you provide the full source code?
Yes! You receive 100% ownership of all source code, fully documented and pushed to your GitHub or GitLab repository.
Will my application be mobile responsive?
Absolutely. Every application I build is fully responsive across desktop, tablet, and mobile devices.
Can you integrate payment systems like Stripe?
Yes, I regularly integrate Stripe, PayPal, and other payment gateways. Subscription billing, one time payments, and invoicing are all supported.
Do you deploy the application?
Yes! I deploy to your preferred platform, Vercel, AWS, Railway, DigitalOcean, or your own server. Your app will be live and production ready.
Can you work with my existing codebase?
Yes! I can jump into your existing React/Next.js/Node.js repo, including apps started in Cursor, Lovable, Bolt, or Replit, to fix bugs, connect backends, add Stripe/AI features, and deploy to production.
How do we communicate during the project?
I provide daily updates via Fiverr chat. For larger projects, I also offer milestone demos so you can see progress at every stage.
What happens after delivery?
Every package includes post delivery support (7-30 days depending on the package). Bug fixes and minor adjustments are covered at no extra cost. Many clients also return for ongoing development.
