I build products end to end: from UI decisions down to cloud infrastructure. Comfortable shipping across language ecosystems and treating infra as a first-class part of the product.

Every project I build is provisioned with Terraform on AWS (Lambda, ECS, RDS, S3, CloudFront, Cognito, SQS, SES) across isolated dev/staging/prod environments with automated GitHub Actions deploys. I also have production experience with GCP and Azure.
