FAQ
What do you need from me to get started?
Clear requirements (endpoints/features list), database choice (MSSQL/MySQL/MariaDB), any existing code/API docs, and third-party keys if needed. Provide as much detail as possible for fast, accurate delivery.
Which databases do you support?
I fully support MSSQL, MySQL, and MariaDB. I can handle schema design, relations, optimization, and complex queries.
Do you include authentication and security?
Yes — Basic JWT in Standard/Premium packages. I implement rate limiting, input validation, helmet, CORS, and best practices for secure APIs. Advanced (OAuth, RBAC) available in Premium or extras.
Will you provide API documentation?
Yes — Standard & Premium include Swagger/Postman collection. Basic package gets simple README/docs. This makes integration easy for your frontend/mobile team.
Can you deploy the backend?
Yes — as a Gig Extra or included in Premium. I set up on Heroku, Vercel, AWS, DigitalOcean, or your preferred host with environment variables and basic monitoring.
Do you offer real-time features?
Yes — using Socket.io or WebSockets for chat, notifications, live updates. This is available as a Gig Extra or in Premium for scalable real-time backends.
What if I need changes after delivery?
Included revisions cover reasonable tweaks. For major changes/new features, I offer Gig Extras or a new order. I provide 1-month support on Premium for bug fixes.
Can this backend connect to my existing frontend or app?
Absolutely — most orders integrate with React, React Native, Flutter, or other frontends. Share your API needs or existing setup, and I'll build compatible endpoints.
How scalable is the backend you build?
I follow best practices for scalability (modular code, efficient queries, caching potential). Premium packages are microservices-ready and handle medium-high traffic.
