FAQ
What exactly do you deliver in each package?
Basic gives you 3-5 clean API endpoints with source code. Standard includes a full API plus one integration with testing. Premium delivers a complete backend system with database setup, documentation, and priority support. Every package includes well-commented code you can extend yourself.
Which third-party services can you integrate?
I work with payment gateways (Stripe, PayPal, Razorpay), email/CRM (SendGrid, Mailchimp, HubSpot), communication (Twilio SMS/WhatsApp), databases (Supabase, PostgreSQL, MongoDB), and most REST APIs with documentation. Just share the API docs and I'll handle the connection.
Do you provide API documentation?
Yes! Standard and Premium packages include Postman collections and clear README files explaining endpoints, authentication, request/response formats, and setup instructions. Basic gets you working code with inline comments.
How long does deployment take, and do you handle hosting?
I deliver fully working code ready for your hosting platform (Vercel, Render, Railway, Heroku). I include deployment instructions, but hosting setup is on your end unless added as a gig extra.
Can you also create frontend development alongside the APIs?
While I can create a basic frontend interface in Standard and Premium packages to test your APIs, for complete frontend development or React web apps, check my other full stack web development gig. Here I specialize in the backend APIs that make your frontend actually work.
Need backend development for your frontend project?
Perfect! I build exactly the REST APIs, webhooks, and database connections your frontend needs. Premium packages include basic frontend testing interfaces. For sophisticated frontend development or single-page apps, visit my frontend development gig.
How do you ensure the security of my application?
I follow best security practice including input validation, token-based authentication (JWT), and secured endpoints to safeguard your data.
Do you also provide support/maintenance after the order is completed?
No, while I will fix small bugs within 2 weeks of the order marking as complete. But for longer maintenance a small monthly maintenance fee will be charged.
