Senior Data & ML Platform Engineer | dutchengineer.substack.com | Host of Ask A Data Mentor Podcast

Built real-time ML systems delivering millions of daily inferences. Integrated LLMs that saved over 1,000 hours per week across the company. Designed scalable MLOps platforms that took model deployment from months to days.

I have spent the last 8+ years driving AI and ML engineering efforts across startups and high-growth companies. My work spans productionizing models, leading company-wide ML initiatives, and building systems that work. 

Highlights:
Led LLM integration at Equipmentshare, embedding OpenAI into internal tooling to save 1,080+ hours weekly
Deployed Zwift’s real-time racing score model, handling 8.6 million inferences per day
Cut ML deployment times from months to 3 days with standardized CI/CD and packaging
Rolled out Databricks company-wide, reducing deployment cycles by 4x
Built ML pipelines for pricing $3B+ in fleet assets, churn risk, and invoice automation

I write often on machine learning systems and infrastructure on dutchengineer.substack.com, and I enjoy helping teams ship fast, reliable ML in production.

Founder & Chief Editor

Validate Health

- Effectively helped lead a tech team of 8 engineers which lead to a 100% retention
rate while I was lead
- Created the testing framework for the company to bolster data pipelines
- Simulated risk scores for all Medicare beneficiaries in the U.S. and shared research
that influenced national policy from CMS that saved ACOs millions
- Used Python, SQL, SAS, Databricks, Airflow, and AWS

Data Science Lead

- Fixed broken data pipelines and improved simulation model accuracy to within 1%
based on translating government policies into SQL data pipelines
- Refactored the internal BI reporting tool built on the Google API to use OOP instead
of functional programming

Data Scientist

Castell 

- Was the lead engineer of automated analytic reporting that was e-mailed weekly to
over 2,400 physicians summarizing value-based care initiative metrics

Technical Data Analyst - Staff

- Designed a Tableau dashboard for the C-suite that gave an extensive overview of key
metrics and was viewed thousands of times
- Used R and Python to create statistical analyses of propensity matched populations

Technical Data Analyst - Associate

Intermountain Healthcare

- Used data analysis skills to resolve an audit that had been ongoing for over 2 years
