About Me


As a Java Backend Developer, I design and optimize Spring Boot solutions for Ethiopia’s largest financial institution. I have implemented Java 21 virtual threads to handle high concurrency workloads efficiently, enabling lightweight asynchronous processing and faster response times. To further enhance performance, I applied strategic pagination, database indexing, and materialized views, resulting in faster processing of large scale financial data.

My approach follows Clean Architecture principles, leveraging Generics to eliminate duplication across modules and maintain consistency. I also integrated OpenAPI documentation, enabling smooth collaboration and maintainability within a 6 person development team. With a focus on scalability, reliability, and clean code, I bring both technical expertise and practical experience in delivering enterprise grade backend systems.
