I will build a secure rest API backend and admin panel for your app
MD Almas Hossen
About this gig
Does your mobile, web, or desktop app need a reliable backend?
I will build secure REST APIs, database logic and an optional web admin panel ready for frontend integration.
What I can build:
- Email and password authentication, roles and permissions
- Modules based on your needs, such as products, bookings, orders, customers, content or custom workflows
- CRUD operations, validation, search, filters and pagination
- MySQL or MongoDB structures and relationships
- File uploads, consistent JSON responses and error handling
- API testing, Postman collection and PDF documentation
- A web admin panel in the Premium package
I work with Laravel, Codeigniter, NestJS, Express.js or NodeJS.
One standard module is one business section with create, list, view, update, delete, search, filters, pagination, validation and simple relationships.
You receive source code, database migrations or schema, documentation, and delivery notes.
Payments, real-time features, advanced reports, complex workflows, third-party integrations, frontend development and deployment are not included unless agreed.
Please message me before ordering so I can confirm the modules, scope, price and delivery time.

I help businesses solve problems that waste time, slow down daily work, or make a system difficult to use and manage. I focus on understanding what is going wrong, why it matters, and what kind of solution will make the process simpler, more reliable, and more effective in real life.
Whether you have an existing system that needs improvement, an unfinished idea, a complicated workflow, or a problem you are not sure how to solve, my goal is to turn it into something practical, stable, and useful.
You bring the problem. I’ll help you find the right solution.

FAQ
What is one standard API module?
One standard module is one business section with create, list, view, update and delete functions, validation, search, basic filters, pagination, simple relationships and standard JSON responses.
How are related sections counted?
Products, Categories, and Tags count as three modules when each needs separate management. If Products only use an existing Category list, that relationship remains inside the Product module.
Which features are not standard modules?
Payments, subscriptions, complex bookings, cart and checkout, shipping, refunds, advanced reports, imports, exports, real-time features and third-party integrations require separate pricing.
What authentication is included?
Basic uses existing authentication or public access. Standard includes email and password authentication with up to two roles. Premium includes up to three roles. OTP and social login..
What does the Premium admin panel include?
Premium includes a template-based dashboard and one matching management section for each agreed module. Custom UI design, advanced analytics and page builders are not included.
Is application frontend development included?
No. This Gig covers backend APIs, database logic, documentation, integration assistance and the Premium web admin panel. Customer-facing web, mobile or desktop frontend development requires a custom offer.
What does a revision include?
A revision corrects work that does not match the approved requirements. New modules, workflows, integrations, endpoints or design changes are additional work.
Can you modify an existing backend?
Yes. I can add or update API modules and admin-panel sections after reviewing the existing source code and project structure.
