FAQ
What backend technologies do you work with?
I mainly work with Node.js, NestJS, TypeScript, PostgreSQL, MongoDB, MySQL, Redis, RabbitMQ, WebSockets, Docker, and AWS. I can also integrate third-party APIs and payment systems such as Stripe.
Can you work on an existing backend project?
Yes. I can review, debug, improve, or extend an existing Node.js or NestJS backend, including APIs, databases, authentication, performance issues, and integrations.
Can you build authentication and role-based access control?
Yes. I can implement secure authentication using JWT and role-based authorization for different user types such as admin, staff, customers, or other custom roles. Your resume supports this with multi-role and secure authentication work.
Can you integrate databases and third-party APIs?
Yes. I can work with PostgreSQL, MongoDB, and MySQL, and integrate services such as Stripe, SendGrid, Twilio, AWS, Google Maps, and other REST APIs depending on your requirements.
Should I contact you before placing an order?
Yes, especially for custom or complex backend requirements. Please share your requirements, existing codebase if applicable, expected features, and preferred technologies so I can confirm the scope, timeline, and best package for your project.
