FAQ
Do you build REST APIs, GraphQL APIs, or both?
I build both! REST APIs are great for standard CRUD operations, while GraphQL is ideal for complex data relationships. I will recommend the best approach based on your specific project needs and help you choose the right architecture.
What database do you work with?
I primarily work with MongoDB and PostgreSQL. I use Prisma or Mongoose as ORM for clean data modeling. MongoDB is perfect for flexible document-based data, while PostgreSQL excels at relational data with complex queries. I will recommend the best fit based on your project requirements.
Do you provide API documentation?
Yes, every API I deliver includes full Swagger/OpenAPI documentation. This provides an interactive interface where you and your team can test endpoints directly. I also include setup guides and code examples to help your frontend team integrate quickly.
