How I Built FGRManager: A Physician-Developer’s Blueprint for Turning Clinical Protocols into Bedside Tools
By Chukwuma Onyeije, MD, FACOG | Maternal-Fetal Medicine Specialist & Founder, Doctors Who Code Atlanta Perinatal Associates Suggested Meta Description: A practicing MFM physician-developer deconstructs how to build a zero-dependency clinical decision support tool for fetal growth restriction management — from SMFM protocol to deployed microsite. It was a Tuesday evening consult. A doctor called […]

From Patient Data to Open Source: Why I Built the Performance Glycemic Intelligence System (PGIS)
As a physician-developer and a 60-year-old endurance athlete living with Type 2 diabetes for over two decades, I have navigated a unique intersection of medicine, technology, and personal health. My journey is a constant balancing act between the drive for athletic performance and the non-negotiable demands of glycemic control. This personal challenge is the crucible […]

The Anatomy of a Real-Time Clinical Presentation: From Clinical Encounter to Open-Source Slides in Minutes
By Dr. Chukwuma Onyeije A few days ago, a consult reminded me why I started this blog . A colleague mentioned a new patient with a complex presentation of placenta accreta spectrum (PAS), specifically a challenging case of placenta percreta. I had an old slide deck on the topic, but I knew it was outdated. […]

From Stethoscopes to Transformers: A Doctor’s Deep Dive into “Attention is All You Need”

Everything else is just efficiency.”— Andrej Karpathy, on his micro-GPT release, February 2026 As physicians, we are trained to meticulously gather and synthesize vast amounts of information before making a critical decision. We review […]

From Misinformation to Implementation: Why Modern Medicine Needs a Guideline-to-App Industrial Complex
By Chukwuma I. Onyeije, MD, FACOGMaternal-Fetal Medicine Specialist, Medical Director at Atlanta Perinatal Associates, Founder of CodeCraftMD I was reviewing evidence-based counseling guidelines for low-dose aspirin in preventing preeclampsia when something bothered me. Not the science—that was solid. The Society for Maternal-Fetal Medicine recommendations are clear, the evidence is strong, and the logic holds up […]

Post-Mortem: Why I’m Stepping Back from My OpenClaw Experiment
In my last post, I shared my journey into building an OpenClaw agent to gain deeper visibility into the development process. As someone fascinated by the intersection of medicine and code, the promise of a highly autonomous, transparent agent was too intriguing to pass up. However, after a period of active experimentation, I have decided […]

Physician-Developers vs. Viral Misinformation
Why Code, Clinical Rigor, and Credibility Matter in the Age of TikTok Medicine When Algorithms Enter the Nursery A mother announces she will refuse vitamin K for her newborn. Not because of documented allergy. Not because of carefully researched religious exemption. Because she “heard something bad about it online.” When I ask what she heard, […]

I Built an OpenClaw Agent to Understand What Developers Are Actually Doing (Not Because I Needed One)
By Chukwuma Onyeije, MD, FACOGMaternal-Fetal Medicine Specialist | Founder, CodeCraftMD | Atlanta Perinatal Associates Here’s the truth about being a physician-developer: you learn by breaking things on purpose. Earlier this week, I set up an OpenClaw agent on Cloudflare. Not because my clinical workflow desperately needed it. Not because I had some grand vision of […]

Part 2: What We Should Actually Build
The Physician-Developer’s Blueprint for Rural AI That Works By Chukwuma Onyeije, MD, FACOGMaternal-Fetal Medicine Specialist & Founder, CodeCraftMD In Part 1, I showed you the math: $50 billion for AI “transformation” while cutting $137 billion from rural Medicaid. A textbook bait-and-switch where vendor-built “avatars” replace actual clinical capacity. But physician-developers don’t just identify broken systems. […]

Part 1: The $50 Billion Bait-and-Switch
How AI “Transformation” Became Cover for Abandoning Rural America By Chukwuma Onyeije, MD, FACOGMaternal-Fetal Medicine Specialist & Founder, CodeCraftMD The pitch sounds good if you don’t look too closely. Fifty billion dollars for “AI transformation” in rural healthcare. Digital assistants bringing 24/7 medical expertise to communities that can’t retain physicians. The promise of technology bridging […]

From Walled Gardens to Living Evidence: Why Evidence-Based Medicine Is Being Rewritten by Compute
The history of medicine is, at its core, a history of how we manage information. For decades, Evidence-Based Medicine (EBM) has been our North Star—a rigorous framework designed to move us from “eminence-based” anecdotes to “evidence-based” certainty. It was a monumental achievement. But we are currently witnessing a quiet yet profound shift in the very […]
