Skilled in building event-driven systems with Apache Kafka, RabbitMQ, AWS SQS, and integrating GraphQL for efficient data handling. My cloud proficiency spans AWS and Azure, including services like EC2, Lambda, AKS, S3, and Key Vault. I bring solid DevOps experience using Docker, Kubernetes, Jenkins, Terraform, and Ansible, with a focus on CI/CD and container orchestration. I’m also well-versed in secure architecture (OAuth 2.0, JWT, SSL/TLS), testing tools (JUnit, Mockito, Selenium, Jasmine), and monitoring stacks like Prometheus, Grafana, ELK, and Datadog. Passionate about Agile delivery and delivering clean, maintainable code with tools like SonarQube and Snyk.
