Senior Java, Kotlin, Android Developer

I specialize in building reliable, maintainable, and scalable software systems with a strong focus on code quality and team collaboration. Clean code, thorough unit testing, and integration testing are core principles in every project I work on.

My primary expertise lies in backend and microservice development, particularly in cloud-based environments. I have extensive experience modernizing legacy and deprecated systems—migrating, optimizing, and improving them for long-term stability and performance.

I’m also experienced in DevOps practices, security considerations, and client-side architecture, enabling smooth delivery pipelines and secure, well-structured applications. While I’m capable of UI development, my strongest impact is in backend design and implementation.

If desired, I also provide developer training, knowledge sessions, and team-upskilling support.

I work with professionalism, clarity, and commitment to high technical standards.
