## What I'm looking for

```text
I'm looking to build reliable, secure production AI and cloud platforms, with meaningful ownership of compliance, observability, data protection, and measurable system outcomes.
```

## About

```text
I'm building and extending GitLab's AI Gateway, routing enterprise AI requests to Anthropic, Vertex AI, and OpenAI while adding entitlement controls, tenant isolation, rate limiting, prompt-injection defenses, PII redaction, and audit logging.

Previously at Canva, I built Spring Boot microservices serving template metadata to 150M+ monthly active users and delivered shared backend services for the Visual Suite. At Rapid7, I built cloud asset harvesting pipelines processing tens of millions of records daily and improved harvest reliability from ~94% to ~99.2%.

Across eClinicalWorks and The Hanover Insurance Group, I've worked on HIPAA-regulated healthcare systems, claims APIs, audit infrastructure, CI/CD, and legacy Java migrations. I build reliable systems, respect production, secure the data, and measure the AI.
```
