What I'm looking for

I seek roles building cloud-native microservices and distributed systems, with strong emphasis on TDD, performance, and DevOps automation in an Agile team.

I am a Senior Full Stack Java Developer with over 10 years delivering large-scale enterprise solutions across GIS, IoT, supply chain, ERP, fintech, and healthcare domains.

I design and implement cloud-native microservices and distributed systems using Java, Spring, event-driven architectures (Kafka, MQTT, RabbitMQ), and modern cloud platforms (AWS, Azure, OCI).

I focus on system design, performance optimization, TDD, and DevOps-driven delivery — automating infrastructure with Terraform and container orchestration with Docker and Kubernetes to improve resilience and CI/CD reliability.

I have led architectural and code reviews, improved production performance with load testing, and consistently delivered production-grade solutions in Agile environments.
