What I'm looking for

I seek senior backend or cloud roles focused on microservices, scalable systems, and continuous delivery in collaborative, engineering-driven teams.

I am a Senior Java Developer with over 10 years of experience designing, building, and deploying scalable enterprise applications using Core Java, Spring Boot, microservices, and cloud-native architectures across AWS, GCP, and Azure. I focus on performance, reliability, security, and clean code, and I have led modernization efforts to containerize monoliths and implement robust CI/CD pipelines.

I have engineered RESTful APIs, asynchronous event-driven systems with Kafka and RabbitMQ, and implemented observability and automation using ELK, Prometheus, Docker, and Kubernetes. I mentor engineers, collaborate with cross-functional teams, and deliver maintainable solutions that align technology with strategic business goals.
