What I'm looking for

I seek roles where I can build cloud-native microservices and event-driven systems, work in agile teams, and drive scalable CI/CD and observability solutions.

I am a Senior Java Full Stack Developer with over 5 years of professional experience building web and distributed enterprise applications using Java/J2EE and modern front-end frameworks.

I design and implement scalable microservices with Spring Boot, Spring Batch, Spring Security, and Hibernate, and have delivered robust single-page applications using Angular and React.

I have extensive cloud and DevOps experience across AWS, Azure, and GCP, leveraging services such as EC2, Lambda, S3, RDS, AKS, ACI, ACR, BigQuery, and Terraform to automate infrastructure and CI/CD pipelines.

I build real-time, event-driven systems using Apache Kafka, Flink, JMS, and various message brokers, and emphasize test-driven development, monitoring, and secure payment processing in regulated environments.
