I used to work as a FileMaker training, developer, and consultant. Worked directly at FileMaker for 7 years as a Solutions Consultant and a Technical Marketing Manager. I'm a FileMaker Certified Developer and an Authorized Trainer.
For the past 5 years, I've been working as a designer focusing on User Experience (UX), Design Research, and Design Strategy. Based on my FileMaker/data background and my UX experience, I love finding ways to storytell with data.
I design data platforms, the governance around them and the AI on them, then build them. Nine years in software, six on production data platforms: a 15 TB+ footprint, 100M+ events a day, 99.9% uptime. I move analytics off the product's Postgres, choose platforms by proof of concept, design governance an auditor can check (SOC 2 readiness), and ship AI agents whose output is typed, evaluated and reviewable.

AI Model Engineer, Operating System Developer, Principal Cloud & Infrastructure Architect with decades of hands-on engineering experience and 10+ years designing, modernizing, securing, and operating production AWS environments.
I specialize in complex environments where **architecture, reliability, security, and hands-on troubleshooting** intersect. My work has included transforming single-server applications into highly available cloud platforms, designing Infrastructure as Code and CI/CD systems, leading zero-downtime migrations, operating mission-critical SaaS infrastructure, and supporting organizations through significant growth and ownership transitions.
Many times I have served as a medium or long term technical consultant and infrastructure owner, working directly with executives, Product, Engineering, QA/Support, and business stakeholders while remaining hands-on with AWS, Linux, automation, security, and production incidents.
More recently, I have applied the same production-first approach to AI infrastructure and agentic systems, building secure cloud environments and AI-enabled operational workflows rather than isolated prototypes.
