DevOps Engineer with 7+ years of overall IT experience and 3+ years of hands-on expertise in Google Cloud Platform (GCP), Kubernetes, and CI/CD automation. Currently at Rakuten India, where I own and operate production-grade infrastructure supporting large-scale web crawler and catalog platforms.

I manage GKE clusters powering microservices that process 500M+ pages annually, operate Cloud Dataflow pipelines handling 18M records/day with Pub/Sub-based event-driven ingestion, and have led cloud architecture migrations that delivered 88.5M JPY (~$600K+) in annual cost savings — all with zero production downtime.

Recognized with two Rakuten Excellence Spot Awards:

• GCP Migration Leadership (Jan 2026) — Led end-to-end cloud migration of the crawler platform from US to JP region, setting up GKE clusters, Pub/Sub, and networking across dev, staging, and production.
• Production DevOps Ownership (May 2025) — Consistent ownership of Kubernetes operations, Cloud Dataflow jobs, CI/CD pipelines, monitoring, and platform reliability.

What I work with daily:

• Production Kubernetes (GKE): Deployments, Services, ConfigMaps, Secrets, HPA, rolling updates
• CI/CD: Migrated Jenkins to Google Cloud Build — 60-80% build time reduction
• Data Pipelines: Cloud Dataflow + Pub/Sub for real-time catalog data processing
• Infrastructure as Code: Terraform for GCP resource provisioning
• Monitoring: Google Cloud Monitoring, Cloud Logging, alerting, incident response
• Networking: VPC design, subnets, DNS, NAT Gateway, firewall rules
• Tools: Docker, Linux, Shell Scripting, Git, GitHub, PostgreSQL, Redis, BigQuery

• Owned production Google Kubernetes Engine (GKE) clusters supporting large-scale crawler microservices processing 500M+ pages annually, ensuring high availability, reliability, and horizontal scalability.
• Owned production Cloud Dataflow pipelines for catalog data ingestion and enrichment, processing 18M records daily while ensuring reliability and scalability.
• Led cloud architecture migrations for the Catalog and Crawler platforms, achieving 30.5M JPY and 58M JPY in yearly cost savings with zero production downtime and improved operational efficiency.
• Designed and implemented VPCs, subnet segmentation, routing, and DNS configurations to support Kubernetes-based workloads during cloud platform migration.
• Implemented rolling and progressive deployment strategies to achieve zero-downtime releases for business-critical services.
• Implemented proactive monitoring and alerting using Google Cloud Monitoring and Logging across GKE and Dataflow, reducing incident response time.
• Modernized CI / CD workflows by migrating pipelines from Jenkins to Google Cloud Build, improving pipeline reliability, security, and maintainability.
• ImprovedCI / CD efficiency bymigrating toGoogle Cloud Build, implementing build caching (60–80%build time reduction), and standardizing artifacts using Google Artifact Registry.
• Designed, deployed, and maintained Kubernetes workloads using Deployments, Services, ConfigMaps, and Secrets following Kubernetes best practices
