Cover image for Custom Backend & API Development
I build reliable backend systems and REST APIs for businesses, startups, and digital products.
From a small API to a complete backend service, I can help turn your requirements into a structured, documented, and maintainable software solution.

What I can build

• REST APIs • Backend applications • Authentication and authorization systems • JWT-based authentication • CRUD systems • Database integrations • PostgreSQL database solutions • API integrations • Business logic and backend services • Swagger/OpenAPI documentation • Dockerized applications • Bug fixes and backend improvements • Existing backend modernization and refactoring

Technology stack

Java, Spring Boot, Spring Security, JPA/Hibernate, PostgreSQL, Docker, REST APIs, JWT, Swagger/OpenAPI, and related backend technologies.

What you get

Clean and maintainable backend code designed around your requirements.
I prioritize clear architecture, reliable business logic, proper API structure, security, documentation, and code that can be maintained and extended as your project grows.
Before development begins, we define the requirements, scope, deliverables, and timeline so there is a clear understanding of what will be delivered.
Send me your project requirements, existing API, repository, or technical specifications to discuss the best approach.
