           I grew up in Fort Smith, Arkansas, in the kind of instability where home is a moving target - roughly thirty addresses before I was fifteen, parents struggling with addiction, the material precarity that comes with all of that. I left home at fifteen, stayed with friends until I finished high school, found my way to college. At fourteen I&#39;d already found software, writing C++ at the public library because it was the first thing in my life that responded to precision with correctness, and that property turned out to matter more to me than almost anything else.

         I dropped out of college, worked, went back as an adult to finish my degree, and built my skills across nearly twenty years and every kind of organization - international consulting, early-stage startups, Fortune 5 enterprises. Logistics, retail, entertainment, hospitality, industrial automation, insurance, healthcare, financial services. I trained under Juval L&#246;wy at IDesign and worked with him as a consultant from 2015 to 2021, which is where I learned what it actually means to practice software engineering as a discipline rather than an improvisation.

         Across nearly twenty years I watched software get built at organizations with real stakes and real consequences, and I watched AI go from promise to product - watched the same mistake get made at each iteration: tools built to serve the organization&#39;s needs, not the person&#39;s. Engagement over relationship. Features over memory. Policies where values should be. The fundamental premise that you are a user, not a person, has been so thoroughly baked into the architecture of every major AI system that it doesn&#39;t register as a choice anymore. It&#39;s treated as the natural condition of the technology.

         Neuron is what I built in response to that. Not a startup in the traditional sense - no team, no funding, no press release - one person, nearly two years of work, and a conviction that this can be done differently. I wrote the memory architecture, I built the inference infrastructure, because the tools that existed weren&#39;t sufficient for what I was trying to build and so I built those too.

         AI has genuine potential to free people to do work that actually matters to them - not to create engagement loops, not to harvest attention, but to actually serve the person sitting in front of it.
