DaVita - Dialysis Machine Uptime at Scale
Completed: 2020-2021
As "Performance Czar" for DaVita's live dialysis-machine integration — direct connections reporting patient bloodwork and machine status to doctors in real time — kept uptime and consistency intact as the rollout scaled to new sites, each one introducing new bottlenecks.
The Problem
DaVita's system integrated directly with active dialysis machines — physical equipment with moving parts — live at a growing number of sites, reporting real-time bloodwork and machine status data to doctors. Each new site added to the rollout introduced new bottlenecks, threatening the uptime and consistency the integration depended on.
The Solution
Served as "Performance Czar," putting SLA benchmarks and a testing culture in place across the growing service ecosystem tied to the live dialysis-machine integrations. Worked with development, testing, and leadership teams to catch and resolve the new bottlenecks each additional site introduced, keeping performance a first-class concern as the footprint scaled.
The Impact
Sustained 99.9% uptime for the live dialysis-machine integration as it scaled to new sites. Built a repeatable process for absorbing the bottlenecks each new location introduced, without compromising the reliability doctors and patients depended on.
