A Career in Cloud Migration & Platform Engineering

Led end-to-end platform modernisation and Kubernetes migration for a securities brokerage's mission-critical trading and internal platforms across GCP and Nutanix. Migration and security hardening are complete; currently providing ongoing technical consultation to the client's engineering team through end of 2026.

• › Led containerisation and migration of ~100 applications to Kubernetes with standardised CI/CD via GitLab CI and ArgoCD, including image governance, deployment controls, and environment separation
• › Owned platform setup across Nutanix (Talos-based clusters) and GCP, with networking, IAM, shared services, and Prometheus/Grafana/Wazuh observability stack
• › Led cutover planning and phased traffic shifts to 100% production with validated rollback plans and zero unplanned downtime
• › Led security audit remediation: GitLab CI/CD pipeline hardening, Terraform IaC guardrails, Kubernetes RBAC and pod security, Secrets management via ESO/Vault migration

Led end-to-end migration of a mobile advertising platform's customer workloads from Azure to GCP, owning both technical execution and program governance for a large-scale, high-throughput platform handling millions of requests per second.

• › Led Azure → GCP migration for mission-critical workloads with zero unplanned downtime and strict delivery timelines
• › Designed and validated cloud architecture capable of handling 4.5M+ requests per second
• › Implemented Terraform-based IaC with Jenkins-driven CI/CD to standardize and automate deployments
• › Defined migration strategy, cutover plans, dependency mapping, and rollback paths

Provided technical leadership during the Mobilize phase of an urban and infrastructure consultancy's on-premises to AWS migration program — covering architecture design, migration planning, and delivery readiness.

• › Guided AWS Landing Zone architecture: account structure, networking, IAM, security baselines, and shared services
• › Supported application portfolio discovery and migration readiness assessment
• › Advised on migration patterns aligned with business risk and delivery constraints
• › Reviewed and validated designs for observability, IPAM integration, service catalog, and centralized networking

Led on-site cloud discovery and migration consulting for a marketing-technology SaaS provider's customer engagement platform across a large, globally distributed AWS footprint.

• › Led discovery covering ~150 services across EC2, EKS, Lambda, and multiple AWS accounts spanning India, US, and EU
• › Assessed complex multi-account AWS architecture with shared databases, queues, and cross-region dependencies
• › Evaluated diverse data platforms including MySQL, MongoDB, Cassandra, DynamoDB, Redis, Kafka, and S3-based data lakes
• › Defined POC scope and target GCP architecture for EU region

Led cloud discovery, migration consulting, and GCP Landing Zone implementation for a logistics-technology company — supporting informed decision-making for a potential AWS-to-GCP migration.

• › Conducted 2-week on-site discovery covering application architecture, infrastructure dependencies, and security posture
• › Performed target architecture design for GCP: workload isolation, networking, IAM, logging, monitoring
• › Built detailed TCO and cost comparison models for leadership evaluation
• › Led implementation of a production-ready GCP Landing Zone

Led internal optimization initiatives: GTM strategy, migration delivery standardization, and ISO audit readiness.

• › Partnered with executive leadership to reassess service positioning and productize internal migration assets
• › Designed standardized migration frameworks — discovery questionnaires, execution playbooks, and governance templates
• › Played a key role in organizational ISO audit readiness, collecting and presenting evidence to external auditors

Led large-scale AWS to GCP migration of Koo's production platform within a strict four-month timeline, achieving zero downtime across 40+ application services.

• › Led end-to-end migration of 40+ application services, 48 ML services, 14 RDS databases, and 7 DynamoDB tables
• › Designed and implemented GCP Landing Zone architecture
• › Planned and executed phased service cutovers with cross-region active users
• › Automated infrastructure provisioning using Terraform and standardized CI/CD using Jenkins

Led migration of Tokopedia's AliCloud-based services to GCP with zero downtime. Recognized as 'Cloud Migration Hero' for leading zero-downtime cutover of critical workloads.

• › Migrated VM-based workloads from AliCloud to GCP with zero service interruption
• › Built infrastructure using Terraform and managed configuration via Ansible
• › Created base VM images using HashiCorp Packer and implemented service discovery using Consul
• › Set up monitoring and dashboards through Datadog and Grafana

Migrated on-premises workloads to GCP: applications on Kubernetes moved to GKE; databases, datastores and some services ran on VMs.

• › Migrated VM-based services from on-prem DC to GKE on GCP
• › Used Terraform to build and manage Kubernetes and underlying GCP infrastructure
• › Implemented monitoring and alerting using Datadog to stabilize post-migration operations
