What I'm looking for

I seek remote roles building scalable distributed systems, emphasizing microservices, CI/CD, cloud-native deployments, reliability, and collaborative Agile teams with opportunities to reduce technical debt and improve system performance.

I am a Senior Java software engineer with 6+ years designing and building high-performance distributed systems, specializing in Spring Boot, Hibernate, and microservices. I have a proven track record optimizing CI/CD pipelines, implementing event-driven solutions with Kafka and RabbitMQ, and deploying containerized workloads with Docker and Kubernetes.

I have driven full lifecycle delivery for SaaS products and freelance projects, refactoring legacy modules into microservices, achieving high test coverage, and reducing technical debt. I routinely collaborate with stakeholders to translate business needs into reliable technical specifications and streamline release processes within Agile/Kanban teams.

I excel in remote, asynchronous environments, managing concurrent projects independently and applying strong time-management and high-frequency interaction strategies to ensure high availability and operational reliability.
