CTO at Provenant · Cloud infrastructure consultant · AWS Community Builder
I design, build and run cloud infrastructure on AWS for companies that need it to be reliable and not expensive. I have shipped production software since 2012, and I went from backend developer to CTO along the way. I still write the code.

I zoom out to set direction and zoom in to fix the exact line that breaks. Most problems need both, and I switch to whichever level the problem needs at the time.
| Zoomed out | Zoomed in |
|---|---|
| Became CTO as Protokol pivoted to building its own product. Now I lead engineering at Provenant, its spin-off. | 8 merged pull requests in AWS CDK, for example a fix for Lambda grantInvoke called twice with different principals |
| Architecture that puts cost first: right-sizing, spot capacity, serverless where it pays off | A Terraform module that runs ECS on a mix of spot and on-demand EC2 |
| Ran a 12-person agency: technical direction, mentoring, growing the client base | Replaced microtime() with hrtime() in Guzzle for monotonic, high-resolution timing |
- AWS architecture: serverless (Lambda, API Gateway, AppSync, DynamoDB, SQS/SNS), containers (ECS, EKS), and cost reduction.
- Infrastructure as code: AWS CDK, Terraform, SST and CloudFormation.
- Delivery: CI/CD with GitHub Actions and CodePipeline, OIDC-based deployments, multi-account AWS.
- Languages: TypeScript, Go, Python, Java and PHP.
