I'm Marc J. Greenberg, also known as CodeMarc, an expert generalist. Some would say I bring the whole π to the table.
Tools change. Craft endures.
My craft is understanding complex systems, finding the patterns beneath them, and turning business intent into technology that works. I've practiced it for 35 years across generations of platforms, languages, architectures, and industry shifts.
Today that craft is amplified by AI coding and reasoning tools. I use them to explore ideas, challenge assumptions, write and test code, and move from strategic direction to working proof much faster. But possessing tools isn't the same as knowing the craft. The real work is knowing what to ask, what to trust, where the risks are, and whether what you've built will survive outside the demo.
Through Braintrailz, I help organizations choose their technology path, modernize systems, and build practical AI-assisted development capability. I work from strategy through implementation, closing the distance between an idea and evidence that it works.
I've been a developer since I was a teenager, and I still jam to that vibe. The tools are astonishing now. The craft still matters.
