Cloud infrastructure, automation & FinOps.

About me

DevOps Engineer focused on cloud infrastructure, automation, FinOps, and governance across multi-account AWS environments (50+ accounts). I design platforms with Infrastructure as Code, CI/CD, Kubernetes (Amazon EKS), and observability so teams get better cost efficiency, reliability, and operational visibility. My background started in development, but today I spend most of my time building the systems that keep infrastructure running at scale.

Traditional Japanese architecture
Build quietly.
Scale deliberately.

Experience

Cloud automation, FinOps, and operations at scale.

2024 – Present

I design and run cloud automation, FinOps, and governance across 50+ AWS accounts. That includes cleanup of unused resources (EBS, snapshots, Elastic IPs, ECR), EC2 scheduling for non-production environments, and cost reporting pipelines with CUR, S3, and Athena (Parquet) that deliver automated PDF/HTML reports.

On governance and observability I built CloudTrail + Athena pipelines for sensitive resource creation, tagging and lifecycle policies, and monitoring with Datadog and CloudWatch, with alerts into Slack, Microsoft Teams, Discord, and Jira.

Platform work covers Amazon EKS (CronJobs, HPA, IRSA, service accounts), CI/CD and Docker images for automation services, and Terraform across multiple AWS accounts. I also built an AI cost assistant with AWS Bedrock, FastAPI, and React for natural language queries over cloud cost and data lake datasets.

Selected projects

Platforms I built for inventory, FinOps, data, and operations.

AWS Multi-Account Inventory Platform

PythonCloudQueryEKSCronJobsCodeBuildS3Athena

Independent inventory platform I designed and built from scratch, inspired by CloudQuery. More than 38 Python scripts extract infrastructure from 50+ AWS accounts, multi-region, and land it in S3 (Parquet) for Athena and analytics. I owned the full delivery: CodeBuild pipeline, Kubernetes namespace, service accounts, IRSA, and every CronJob that keeps the inventory fresh. The result is organization-wide visibility for auditing, governance, and FinOps across EC2, RDS, IAM, S3, and networking.

FinOps Automation Platform

AWSTerraformKubernetesCI/CDCronJobs

Automation ecosystem that optimizes cloud costs and enforces governance across 50+ AWS accounts. Workloads run as Kubernetes CronJobs (cleanup of unused EBS, snapshots, Elastic IPs and ECR, plus non-prod EC2 scheduling) with Terraform and CI/CD around them. Cost reporting uses CUR, S3, and Athena to produce automated PDF/HTML reports.

Licenses & Vendors Platform

CronJobsHTMLNetSuiteS3AthenaQuickSight

License cost automation: CronJobs generate an HTML dashboard with monthly spend for Claude, Cursor, JetBrains, Jira, Microsoft, and more. It tracks org structure, seats, and cost per seat, adding new users as they appear. On the vendor side, NetSuite exports are automated, stored in S3, queried with Athena, and visualized in Amazon QuickSight.

Data Catalog

RDSAuroraPostgreSQLPythonS3

Centralized inventory of tables and schemas across RDS Aurora, PostgreSQL, and other databases. It gives teams a single catalog of data assets so they can discover, audit, and govern schemas instead of hunting them account by account.

NOC AI Agent (Copilot Studio + Teams)

Copilot StudioMicrosoft TeamsConfluenceObservability

AI agent for the NOC, built in Copilot Studio and integrated with Microsoft Teams. It connects observability alerts with escalation paths and Confluence runbooks so operators get the next steps for an alert without leaving Teams.

AI Cost Assistant

AWS BedrockFastAPIReact

Conversational interface over cloud cost and data lake datasets. Natural language queries go through FastAPI and AWS Bedrock so FinOps questions can be answered without writing SQL.
