Raymond Krehn

Welcome to my personal site. I live with my wife and two sons in Highlands Ranch, CO. I've spent 15+ years in product management and technology, turning manual, messy processes into software that works. This is where I share some of my projects and write about what I'm learning along the way.

A Few Things I'm Proud Of

Growing a Platform

Helped a home care platform grow from 3 pilot agencies to 60+ and 30,000+ caregivers, including a GPS-verified mobile app with 4,000+ daily users and integrations that now process over $1M in claims every month.

Building Instead of Buying

I like a good scrappy solution. A self-built Excel automation tool replaced a $20,000/month third-party contract, and a self-service help hub cut recurring support requests by nearly two-thirds.

Turning Things Around

An automated billing engine turned an unprofitable healthcare service line profitable: $2M in the first year and $10M over four. A custom scheduling system avoided $2M a year in overtime.

Data That Helps People

I designed a probabilistic patient-matching system that gave clinicians back an estimated 125,000–250,000 hours a year to spend on patient care, and built predictive models to flag patients who needed extra attention.

Making Systems Talk

Healthcare data is messy. I've built integrations that turn raw lab-instrument output into standard HL7 messages and connect platforms to state compliance systems and clearinghouses.

Better Ways of Working

I've coached 20+ teams through Lean Six Sigma and moved an engineering team from one release every 3–6 months to shipping bi-weekly. Redesigning one workflow cut 4,000 hours of overtime a year and improved productivity 28%.
