What I'm looking for

I seek a mid-to-senior role building scalable microservices and cloud-native applications, with strong DevOps/CI-CD practices and collaborative Agile teams.

I am a Java Full Stack Developer with over 5 years of experience building and optimizing production applications using Core Java, Spring Boot microservices, Hibernate ORM, and modern front-end frameworks such as Angular and React. I have delivered end-to-end solutions across Agile teams, improved system reliability through migration and refactoring, and integrated cloud services (AWS/Azure) to enhance performance and scalability.

I excel at designing RESTful APIs, implementing CI/CD pipelines, and resolving production issues while maintaining strong user experience through responsive web development. I bring practical experience with messaging systems (Kafka), database technologies (MySQL, SQL Server, MongoDB, Cassandra), and automation tools (Jenkins, Liquibase), and I am committed to clean, maintainable code and continuous improvement.
