I have extensive experience developing predictive applications using Java (Spring Boot, Spring WebFlux) and GraphQL APIs, integrating technologies like Bigtable for scalable data storage and Vertex AI for machine learning model deployment. I’ve designed and implemented observability solutions for monitoring, logging, and tracking, leveraging BigQuery for data storage and OpenTelemetry to export metrics to Google Cloud Monitoring, enabling centralized performance monitoring and alerting. Additionally, I built a real-time messaging system with Google Cloud Pub/Sub, optimizing communication and message delivery across systems. I also implemented CI/CD pipelines with GitHub Actions to automate builds, tests, and deployments, ensuring efficient workflows. To maintain software reliability, I developed regression tests using Cucumber, enabling automated validation and verification of updates before deployment.
