At Probability Inc., I build and run production AWS systems for Japanese clients, from infrastructure design through application code and support. For a healthcare result-delivery platform, I built an ingest pipeline from on-prem SQL Server to AWS, using a Python batch, API Gateway, Django on ECS Fargate, and RDS PostgreSQL.
I provisioned that platform with Terraform, including its VPC, Site-to-Site VPN, WAFv2, and monitoring. I also handle production incident triage, scaling, and performance tuning.
For a corporate website, I designed and built a modular Terraform platform spanning CloudFront, WAF, ALB, ECS Fargate, Amplify, and RDS MySQL. I hardened access controls and reduced monthly costs by changing the development environment’s NAT setup, right-sizing RDS, and removing unused resources.
On a multi-cloud Next.js platform, I delivered AWS and Azure infrastructure with AWS CDK and Serverless Framework, and built APIs with Hono, GraphQL, and Prisma. I hold AWS Certified DevOps Engineer – Professional, Solutions Architect – Professional, and Security – Specialty certifications.
