I’m an OCP-certified Java developer with 4 years of experience building and maintaining production-ready back-end systems using Spring Boot.
I specialize in designing clean, scalable REST APIs, implementing secure authentication (JWT), and delivering reliable solutions that are easy to maintain and extend. I’ve worked extensively with MySQL, Redis, and Docker, and I’m comfortable handling the full lifecycle of a feature—from development to deployment.
Beyond back-end development, I also build full-stack applications using Angular, allowing me to deliver complete, end-to-end solutions when needed.
I’ve contributed to real-world systems in industries like telecommunications and insurance, improving performance, reducing manual processes, and ensuring system reliability in production environments.
What I can help you with:
Build or extend Spring Boot REST APIs
Fix bugs and improve back-end performance
Implement authentication & authorization (JWT, RBAC)
Design clean database structures (JPA, Hibernate)
Integrate front-end applications with back-end services
Dockerize applications and improve deployment workflows
How I work:
I focus on writing clean, maintainable code and communicating clearly throughout the process. I aim to deliver solutions that not only work but are easy to understand and scale.
Available for both short-term tasks and longer-term collaborations.
