Lloyds Banking Group

Cloud API Platform / DevOps Engineer

Worked within Cloud Platform API team to design and build Apigee X platform on Google Cloud, enabling secure, scalable, and centralized API management for bank’s enterprise API ecosystem.

Tech Stack: Apigee X, Google Cloud Platform (GCP), Terraform, Jenkins, Harness, Kubernetes, Envoy Proxy, mTLS, Node.js

Key Contributions

• Designed and implemented a secure external API gateway using Apigee X, enabling controlled exposure of internal banking services to external consumers.
• Built reusable Terraform modules to automate provisioning and configuration of cloud infrastructure and platform components including Apigee resources, log sinks and log buckets
• Implemented GCP networking architecture using Internal Load Balancer (ILB), External Application Load Balancer (ALB), and Private Service Connect (PSC) to enable secure service connectivity.
• Built and managed centralized logging architecture using Google Cloud Logging, implementing Log Sink and Log Bucket modules to route and store platform and audit logs.
• Deployed and managed Envoy Proxy on Kubernetes clusters to support scalable and reliable API traffic routing.
• Developed and maintained Helm charts to manage Kubernetes deployments and simplify configuration management across environments.
• Implemented Workload Identity Federation to securely allow Kubernetes workloads to authenticate with Google Cloud services without using long-lived service account keys.
• Led migration of CI/CD pipelines from Jenkins and Spinnaker to Harness, improving deployment automation and pipeline reliability.
• Designed and implemented multi-region deployment architecture to support high availability for bank’s Category A critical services.
• Conducted multiple Proof of Concepts (POCs) to evaluate and introduce new platform capabilities and performance improvements such as enabling gRPC capability on Apigee X, Certificate Revocation List (CRL) validation at gateway layer to strengthen mTLS certificate security, etc.
• Developed Node.js-based deployment and automation scripts to streamline platform operations and API deployment workflows.
