FAQ
Do you provide source code and documentation?
Yes, full source code is always included. I provide a clean, commented codebase + basic documentation (e.g., setup instructions, API endpoints via Postman collection for Standard/Premium packages).
Can you deploy the app for me?
Basic deployment (e.g., Vercel for frontend, Heroku/Render for backend) is included in all packages. For Premium, I handle full server setup (e.g., AWS, DigitalOcean, domain + SSL). Let me know your hosting preference upfront.
Do you offer ongoing support or maintenance?
Yes – 1 week included in Standard, 1 month in Premium. After that, I offer monthly maintenance packages (bug fixes, updates, small features) as an extra service. Message me for details.
Can you add features like payments, real-time chat, or authentication?
Absolutely – authentication (JWT/OAuth), payments (Stripe/PayPal), real-time (Socket.io), file uploads, admin panels, etc., are common. These are included in Premium or added as extras in lower packages.
What happens if the project takes longer than estimated?
I communicate daily/weekly updates. If delays occur due to changes in scope or late client feedback, I’ll discuss extensions transparently. Most projects are delivered on or before the promised time.
Do you work with existing projects or only from scratch?
Both! I can build from scratch, fix/improve existing code, add features, migrate databases, or refactor old apps. Share your repo/link/details for a free assessment and accurate quote.
