Experience
IaC Packages for Microsoft Azure Infrastructure
The use of infrastructure as code ensured GitOps principles were applied, strengthening the audit and tracing capabilities of the system. Because of this and other controls, the system could meet the stringent security requirements of KPMG Japan and KPMG International.
Automation Pipelines for Azure Infrastructure Deployment
The pipelines handled various tasks, such as infrastructure deployment, RBAC assignments, database migrations, secret rotations, etc.
Elasticsearch Cluster to Index and Search Emails
I designed the architecture, presented it to stakeholders, built the infrastructure on AWS, wrote the worker code with Python, and handled the migration of more than 1,000 tenants to the new search cluster.
The project reduced the search latency from minutes to sub-seconds and resulted in overwhelmingly positive customer feedback.
