Hi! I’m a Java Spring Boot backend developer with experience in building REST APIs, database models, and backend logic. I can help you create clean, secure, and high-quality APIs using Spring Boot, MySQL, and modern development practices. I always focus on fast delivery, clear communication, and professional code.
FAQ
What technologies do you use for backend development?
I use Java Spring Boot, Spring MVC, Spring Data JPA, Spring Security, Spring Cloud, REST APIs, Swagger/OpenAPI, MySQL, PostgreSQL, Oracle, Redis, and Docker. All solutions follow clean architecture and enterprise-level best practices.
Can you build complete Spring Boot microservices?
Yes! I design and develop fully independent microservices with API gateways, service registry, load balancing, caching, authentication, and Docker support—ready for production use.
Do you handle authentication and security?
Absolutely. I implement JWT, OAuth2, role-based access, input validations, exception handling, encryption, and secure coding standards used in banking and finance systems.
Can you integrate external APIs or third-party services?
Yes, I can integrate payment gateways, POS systems, CRMs, ERP systems, SMS/email services, or any REST/JSON/XML-based API using Java/Spring Boot.
Will you document the API endpoints?
Yes. I can provide Swagger/OpenAPI documentation, Postman collections, sample requests/responses, and database structure depending on the package you choose.
Can you optimize or fix my existing Spring Boot project?
Of course. I can fix bugs, refactor code, improve performance, optimize queries, add missing features, clean architecture, and make your backend production-ready.
Do you offer database design as well?
Yes. I design normalized database schemas, relationships, indexing strategies, stored procedures, and entity mappings for MySQL, PostgreSQL, or Oracle.
How do you ensure code quality?
Every delivery includes clean code, layered structure, DTOs, validations, error handling, logs, and industry-grade best practices I’ve used in enterprise projects.
What if I need a complete backend system?
Choose the Premium package, or message me for a custom offer. I can build an entire microservice, backend module, onboarding system, or full enterprise solution.
Do you provide support after order completion?
Yes. I provide free post-delivery support within the Fiverr guidelines and can offer extended support for long-term projects.
