A closer look at three projects

Mantle shows my current product and engineering work, Edves shows product work at scale, and the SEO dashboard shows how I build backend systems.

01ProductEngineering

HealthTech / 2023-present

Mantle EHR

I help decide, build, test, and release the workflows mental health practices use every day

usemantle.com

100+Providers supported

28,800+Session notes processed

16,000+Claims handled

30%Reported admin reduction

The problem

Providers lose time when notes, billing, claims, and patient workflows live in separate systems.

My work

I write workflow specs, define release checks, reproduce production issues, and contribute to provider and operations code.

The standard

Every workflow should be clear to the provider, testable by the team, and observable after release.
