FAQ
What technologies do you use for backend development?
I mainly work with Python, using frameworks such as FastAPI, Flask, and Django. I also work with databases, REST APIs, authentication systems, third-party integrations, and deployment-ready backend structures.
Can you build a complete backend from scratch?
Yes. I can design and build a complete backend system from the ground up, including API architecture, database structure, authentication, business logic, integrations, and deployment setup.
Do you work with existing backend projects?
Yes. I can review, fix, improve, or extend an existing backend project. This includes bug fixes, performance improvements, new API endpoints, database updates, and code restructuring.
Can you integrate a database into my backend?
Yes. I can integrate databases such as PostgreSQL, MySQL, SQLite, or MongoDB, depending on your project requirements. I can also design database models, relationships, and queries.
Can you build REST APIs?
Yes. REST API development is one of the main services I offer. I can build clean, scalable, and well-structured APIs for web apps, mobile apps, SaaS platforms, dashboards, and internal tools.
Can you add authentication and user management?
Yes. I can implement authentication features such as login, registration, password hashing, JWT authentication, role-based access, protected routes, and user management flows.
Do you provide source code?
Yes. Source code is included based on the selected package. The code will be clean, organized, and structured so it can be maintained or extended later.
Can you deploy the backend?
Yes. Deployment can be included depending on the package or added as an extra service. I can help prepare your backend for production and deploy it to cloud or server environments.
What do you need from me to start?
I need a clear description of your project, required features, preferred technology stack if any, API requirements, database details, and any existing code, documentation, or design references.
Can you build both backend and frontend?
My main focus is backend development, APIs, and infrastructure. I can also support frontend integration when needed, especially connecting frontend apps to backend APIs.
