About me

HRIS Manager at SC Johnson · Wisconsin, USA

I lead HR reporting and automation, turning HR data into reports and building the tools that take repetitive work off people's plates. Outside the office I write open-source software, including Obsidian plugins with more than 1,700 stars on GitHub.

What I do

HR reporting

Reporting domain lead for the HR department: turning Workday data into Power BI and Excel reports, and building visualizations that support decisions.

HR automation

Automating HR processes and data flows across Workday and ServiceNow with Automation Anywhere, VBA and Python, so recurring work runs without manual steps.

Software development

Web applications in Django and React, and open-source plugins in TypeScript. This site is my own Django, PostgreSQL and Celery stack running on Docker.
