Public sector

State agency work

Government systems where accuracy, availability and cost all matter.

South Carolina Department of Social Services

Half a million dollars back from the mainframe

DSS was paying heavily for mainframe support driven by runaway database load. I audited how the agency's developers were querying the mainframe database and identified every pattern forcing full table scans — queries leaning on unsupported indexes, and a range of other costly practices.

Correcting those patterns removed the load at its source and saved the agency roughly $500,000 in mainframe support costs.

State of Florida

The Florida Baker Act website

Wrote the State of Florida's Baker Act website — the public-facing site for the Florida Mental Health Act, serving families, clinicians, law enforcement and the courts who rely on it to understand and carry out the process.

Government work where accuracy and availability matter, because the people reading it are often in the middle of a crisis.

Applied AI

AI in production, in the cloud and on the edge

AI isn't a slide in a pitch deck here — it's shipping inside every DataGamut product. I work across hosted models and fully local ones, and choose between them based on cost, privacy, connectivity and what the task actually needs.

Local AI · Ember

Private AI with no internet and no subscription

Ember runs large language models entirely on a Raspberry Pi 5 through Ollama. Each user keeps their own chat history and picks which installed model to talk to.

For plant identification from photos, I benchmarked vision models head to head on the Pi and selected Qwen3-VL for its accuracy over faster alternatives.

AI analytics · DDSiq

Insights layered onto 30 years of practice data

DDSiq feeds report data to OpenAI to produce plain-language analysis alongside the numbers, so practice owners and managers see what a report means, not just what it says.

Generative AI · RPGdna

A paying business built on generation

RPGdna's core product is AI-generated game content, metered through a token economy and tied to PayPal subscriptions — real usage controls and revenue wrapped around the model calls.

AI-assisted development

Every platform on this site was built with AI as a development partner

RPGdna, Ember, Fabi Tax Services and the DDSiq migration were all developed hand in hand with AI coding assistants — for architecture, implementation, debugging and modernizing legacy code.

Twenty-five years of experience decides what gets built and whether it's right: root-causing problems before fixing them, reviewing every change, and owning the result. AI speeds up everything in between. For clients, that means legacy modernization and new builds delivered faster, without cutting corners.

How I can help

Legacy modernization

Access, VB.NET and aging line-of-business apps moved to modern .NET and Blazor — without losing decades of data, and accelerated with AI-assisted development.

Database performance

Finding the queries, indexes and habits that drive load and cost — then fixing them at the source.

SQL Server engineering

Stored procedures, schema management, duplicate prevention, ETL pipelines and RDLC reporting.

AI integration

Adding AI to existing systems — hosted or fully local — with sensible guardrails on cost and data privacy.

Government & healthcare

Experience with the accuracy, privacy and accountability these systems demand.
