Learning in public since the mainframe era

Daniel “Dan” Barbatti: AI, Data Science & Agent Systems

My journey from demographic data and forecasting to machine learning, multimodal creativity, and practical AI agents.

A 2026 note: I am still learning, experimenting, and sharing what works. Modern AI can feel new every week, but the central questions are familiar: What problem are we solving? What evidence says the system works? How do we use it responsibly?

The journey

1978–1979
Data and early AI. My first IT work at the University of Missouri's Urban Information Center involved demographic and census data. In college, a group of us wrote a checkers-playing program in LISP on a mainframe.
1980s onward
Forecasting and enterprise systems. At Southwestern Bell and later AT&T-related roles, I worked with capacity planning, mainframe utilization, predictive models, systems management, and the practical realities of large organizations.
2010s–2020s
Cloud, data science, and machine learning. I revisited advanced modeling as tools became more accessible, while continuing work in technical architecture, cloud implementation, and automation.
Today
Agents and multimodal AI. I work hands-on with modern language models, retrieval and memory systems, image and video generation, synthetic voice, music, and cross-platform creative workflows.

What matters more than the buzzwords

Start with the problem

A sophisticated model without a useful business or human purpose is merely an expensive demonstration.

Judgment beats mystique

You do not need to build the microwave to use it well. Deep theory helps, but problem framing, testing, and communication often decide whether a project succeeds.

Verify the result

AI systems can be impressive and wrong at the same time. Evidence, reproducibility, privacy, and honest limits belong in the workflow.

Current work

Agent systems: building and studying practical assistants with memory, retrieval, scheduled work, tool use, recovery, and human oversight.

Zara: a multimodal AI creator project that combines character consistency, voice, music, images, video, storytelling, and conversation.

Independent creative work: experimenting with original songs, visual narratives, and ethical ways for small creators to use advanced tools without pretending the tools are magic.

Recommended starting points

Think in decisions

Ask what decision the data or model should improve, and how you will know that it did.

Learn by building

A small end-to-end project teaches more than a folder full of untouched tutorials.

Keep the human in charge

Use automation to extend attention and capability—not to hide responsibility.

One book I still value is Data Science for Business, especially for connecting analytical work to business value. I also recommend the practical explanations of decision intelligence educator Cassie Kozyrkov.
