Riva Health Inc.
- Led development, testing, and documentation of a macOS app used in clinical research on the world’s largest health problem (heart disease), using SwiftUI, async-await operations, and Qase.
- Aided development and testing of an innovative on-device blood pressure monitor SDK, building a pre-recorded video injection layer to exercise the SDK through a myriad of real-life scenarios across a matrix of human factors (like BMI and skin tone) and environmental factors (like ambient light and temperature).
- Filled critical holes in the early team by being flexible, responsive, willing, and able to work across many platforms and functions.
“Hands down, I will always recommend Christoph to any one and every one who might be fortunate enough to work with him. Christoph is not only an exceptional engineer, but also an exceptional person. He brings a great deal of experience, clarity, hard-earned wisdom and design insight that is invaluable to all teams, big or small. If there were ever a person who you wanted on your team both from a cultural / personality side and also a sheer engineering / design ability and determination side, Christoph is it.”
