Java Full Stack Developer at Scotia Bank building GCP microservices and real-time transaction pipelines for fraud analytics.

Message

At Scotia Bank, I led the migration of AWS-based workloads to Google Cloud Platform and designed Spring Boot microservices on GKE. I also built real-time transaction monitoring pipelines with Pub/Sub, Dataflow, and BigQuery for fraud analytics.

I developed OAuth2-secured REST APIs and Java microservices, and used Cloud Build and Terraform to deploy and provision services. I also established reliability metrics and mentored junior engineers in GCP architecture and secure DevOps automation.

Previously, at RBC and Canada Life, I developed cloud-based financial applications and backend services using Java, Spring Boot, and streaming technologies. At Infosys, I developed patient management systems and integrated healthcare applications using FHIR and HL7 standards.
