About

I'm a creative, detail-oriented information technology professional with a unique blend of technical proficiency and interpersonal communication. My foundation in web development, programming, database design, and marketing analysis is coupled with management, accounting, finance, statistics, and ethical decision-making.

I'm also fully embracing AI as a development partner - pairing with Claude to architect, debug, and ship complex systems at a pace that would have been unthinkable a few years ago. Two decades of hard-won judgment about what scales, what breaks under load, and what real users actually need is exactly what turns AI from a novelty into a force multiplier. The result feels like a superpower: the experience to know what should be built, paired with the velocity to actually build it.

Beyond the stack, I bring expertise in graphic design, photography, photo & video editing, creative writing, and musical composition. I've delivered multiple tech-related public speaking engagements and partnered with marketing teams to align technology with organizational goals.

I pride myself on being a problem-solver and out-of-the-box thinker - drawn to complex challenges and the creative expression they invite.
