What I'm looking for

I want to join an engineering team that values technical excellence and reliability, working on scalable backend platforms, microservices, and cloud-native deployments with opportunities for growth.

I am a results-driven Java Backend Software Engineer with over four years of hands-on experience designing and optimizing high-performance, scalable backend systems.

I specialize in Spring Boot and microservices architecture, building RESTful APIs and secure integrations using tools like Keycloak, Kafka, and RabbitMQ to enable real-time processing and reliability.

My work includes building a scalable bill payments service used across multiple bank channels, enhancing core banking systems, and implementing CI/CD and containerized deployments with Docker, Kubernetes, Argo CD, Tekton, and GitLab.

I seek to join engineering teams that value technical excellence, innovation, and reliability, where I can contribute clean, maintainable code and help platforms scale with business needs.
