FAQ
What do you need from me to get started?
I’ll need a clear description of your requirements. If you have an existing codebase, API documentation, database schema, or architecture diagram, please share those as well. If you’re starting from scratch, I’ll guide you step-by-step.
Can you build a complete REST API from scratch?
Yes, I can design and develop a fully functional REST API using Java Spring Boot, including database integration (e.g., PostgreSQL, MySQL), proper architecture (MVC, layered), and best practices (DTOs, services, exception handling, etc.).
Do you provide microservices architecture?
Absolutely! I can design and implement microservices using Spring Boot, Spring Cloud, Eureka, Gateway, Config Server, and more. I also offer containerization using Docker if needed.
Will you document the API?

Do you follow best practices and clean code principles?

Can you work with an existing project and fix issues or add features?
Yes, I can review your existing codebase, debug issues, improve performance, or implement new features as per your requirements.
What if I’m not technical—can you still help me?
Absolutely. I will explain everything in simple terms and guide you through each step. You don’t need to be technical to work with me!
Do you offer database design and integration?
Yes. I can design relational database schemas, implement JPA/Hibernate entities, write queries, and manage database migrations using tools like Flyway or Liquibase.
Can you integrate third-party APIs or payment gateways?
