Who I Am

About Me

I am a passionate and results-driven Java Backend Developer with over a year of professional experience in building scalable, high-performance applications. Currently working at Datagateway, I specialize in designing robust backend architectures using Java, Spring Boot, and Microservices.

My technical expertise lies in developing secure RESTful APIs, managing complex database interactions with Hibernate, and deploying containerized applications on AWS. I have a strong foundation in optimizing code for efficiency, ensuring seamless integration between frontend and backend systems, and maintaining code quality through rigorous testing.

Beyond coding, I am a continuous learner who thrives in Agile environments. I am eager to tackle new challenges, solve complex logic problems, and translate business requirements into effective technical solutions.
