Data Driven Health: How I Hacked My Health, Fixed Chronic Illnesses, and Survived Emergency Surgery with DIY Open Source Tools

By Roberto Rosario

Book Overview

What if your body's warning signs were debug logs, and you had the tools to read them?

For years, I lived with chronic gut issues, brain fog, joint pain, and a misfiring heart. None of it made sense-especially not to the doctors. Test after test came back "normal." Yet I felt like things were falling apart.

And in 2016 they finally did.

That's when my background in software development kicked in. After three decades spent debugging systems, I turned those skills inward. If the body is a system, then maybe I could trace the errors, map the patterns, and find the root cause.

Data Driven Health is the true story of how I became my own system analyst. Using open-source tools, a DIY EKG monitor, and a custom-built health journaling platform, I uncovered the real drivers behind my chronic illnesses-and reversed them.

By correlating everything from diet and sleep to stress and biomarkers, I realized the "healthy lifestyle" I'd been following was making me sicker. In 2016, I built the OpenHolter and a personalized nutrition framework. It restored my health.

In 2025, it saved my life.

After a ruptured appendix and emergency intestinal surgery, my recovery shocked doctors: no complications, rapid healing, and near-perfect labs. My secret? Years of self-tracking, metabolic optimization, and data-informed nutrition.

If you're an engineer, developer, maker-or just someone who's tired of cookie-cutter health advice-this book is your invitation to take back control.
