FAQs
What kind of projects do you specialize in?
I specialize in building backend systems, including RESTful APIs, database design, authentication systems, and integrations with third-party services, using PHP and Node.js.
Can you work with an existing backend system?
Yes, I can improve, debug, or extend existing backend systems, ensuring compatibility with your current architecture.
How do you ensure the security of the backend system?
I implement best practices such as input validation, encryption, secure authentication methods (e.g., JWT, OAuth), and regular vulnerability testing to ensure your system is safe.
What kind of databases do you work with?
I am experienced with relational databases like MySQL and PostgreSQL, as well as NoSQL databases like MongoDB.
Will you provide documentation for the backend?
Yes, I deliver detailed documentation for the backend, including API endpoints, database schema, and deployment guides.
Do you offer support after the project is completed?
Yes, I offer post-project support for bug fixes and minor changes. For long-term maintenance, we can discuss a separate arrangement.
How do you handle deployment?
I deploy backend systems on cloud platforms (e.g., AWS, DigitalOcean) or containerized environments like Docker, ensuring smooth operation in production.
