What I'm looking for

I seek backend/cloud roles where I can design scalable, reliable systems, work in Agile environments, and continue advancing cloud-native and automated testing skills.

I am a Java software engineer with seven years building scalable, high-performance enterprise systems for banking and public-sector clients, combining strong backend expertise with cloud-native design and automated testing practices. I hold AWS and Oracle Java certifications and recently completed a Higher Diploma in Computing in Dublin while continuing freelance development work to broaden my international experience.

My career highlights include architecting asynchronous processing engines with Spring Batch and AWS SQS, implementing DynamoDB and Redis caching to achieve sub-second API responses at scale, and contributing to large retail investment platforms and government workflow digitization. I emphasize TDD/BDD, mentoring junior engineers, and delivering reliable solutions in Agile teams.
