I'm a Validation Engineer with 20+ years of experience in GxP-regulated biotech environments, including a decade at Genentech and contract work supporting major biotech clients through Advent Engineering. My expertise spans the full validation lifecycle — IQ/OQ/PQ, change control, data integrity, and regulatory compliance under 21 CFR Part 11 and ISO 9001.

Alongside my validation career, I've developed hands-on software and cloud skills through development rotations at Genentech (React/TypeScript and Python/ML) and an ongoing focus on AWS architecture. I hold four AWS certifications and a HashiCorp Terraform Associate, and I'm currently applying this combination to digital transformation initiatives in the life sciences industry.

This site documents my cloud projects and learning journey, and is itself built on AWS services — CloudFront, S3, Lambda, DynamoDB — with Terraform-managed infrastructure and CI/CD pipelines.
